XCP-ng needs guest tools to be installed in the VMs in order to communicate with the guest operating system. This brings better performance and is required for various features.

In short: always install the guest tools to your VMs.

The tools are made of two main components:

  • kernel drivers for the OS
  • a management agent

# Linux

Xen guest drivers have been built-in in the Linux kernel for many years. All currently supported Linux distributions include them.

So all we need is to install the management agent, which comes either as a systemd or as a sysvinit service, depending on the Linux distribution. The service is usually named xe-linux-distribution.

Those guest tools can be installed:

  • from the target distribution's online repositories if available
  • from the Guest Tools ISO image that can be attached to any VM in XCP-ng

# Install from the distro's online repositories

Distros often have policies that forbid enabling new services by default, so most of the time the steps are:

  • enable the appropriate repository
  • install the package from it
  • enable the service

# CentOS and Fedora

Enable the EPEL repository in the VM, then:

The service is not enabled by default, so enable it and start it:

# Alpine

Enable the community repository in /etc/apk/repositories, then:

The service is not enabled by default, so enable it and start it:

# Ubuntu

Feel free to add other distros to the above list if they provide the tools in their repositories.

# Install from the guest tools ISO

# 'Supported' Linux distributions

For distros that are supported by the install.sh script (Debian, CentOS, RHEL, SLES, Ubuntu...), the process is:

  • Attach the guest tools ISO to the guest from Xen Orchestra or using xe.
  • Then inside the VM, as root:
  • No need to reboot the VM even if the script asks to. That's an old message from back when it was needed to install a kernel module in addition to the management agent. We'll get rid of it at some point.
  • Eject the guest tools ISO

# Derived Linux distributions

If your Linux distribution is not recognized by the installation script but derives from one that is supported by the script, you can override the detection and force the tools to install by using:

Examples:

The likeliness for the installation to work correctly will depend on how much those distros differ from their 'parent'.

# Other Linux distributions

For the remaining Linux distributions, mount the guest tools ISO as described above, then look for the xe-guest-utilities_*_all.tgz archive. Copy its contents on the system in /etc and /usr. It contains a System V init script by default but there's also a systemd unit file available on the ISO (xe-linux-distribution.service).

See also Contributing below.

# Update the guest tools

It's a good habit, and may be even required in some cases (that would then be described in the Release Notes, to update the guest tools to their latest version when your XCP-ng hosts are updated.

Depending on the situation, just update from your distribution's online repositories, or follow the above installation process again.

# FreeBSD

FreeBSD is a 30-year-old operating system used widely to run all sorts of systems and has served as the basis for a number of operating systems, including MacOS, pfSense, and FreeNAS. The Xen kernel modules are built and distributed in the GENERIC kernel, so if you haven't customised or recompiled your kernel, the drivers will be present.

To communicate with the hypervisor, you need to install two ports(opens new window):

The install.sh script on the guest tools ISO does not yet support FreeBSD, so there is no point in mounting the guest tools ISO on a FreeBSD VM.

To manually install xe-guest-utilities from a package(opens new window) you can run:

By default the xe-daemon will run if FreeBSD detects the Xen hypervisor at boot. If that autodetection fails for some reason, you can force it to try by putting xenguest_enable=YES in your rc.conf file: sysrc xenguest_enable=YES.

Run service xenguest [stop|start|restart] to respectively stop, start, or restart the xe-daemon.

# OpenBSD

On OpenBSD, the xen drivers are also already part of the kernel. The install.sh script doesn't support OpenBSD, but there are ways to install the management agent anyway.

TIP

For OpenBSD search the forum(opens new window). See for example this thread(opens new window).

# FreeNAS/TrueNAS

FreeNAS is a locked-down version of FreeBSD, with many packages disabled to ensure a more stable environment for the fileserver. xe-guest-utilities is part of the packages that are not available in FreeNAS. But because it's based on FreeBSD, the packages from that OS can be installed, at your own risk. This is not a big issue for this particular package, because it's a leaf in the chain of dependencies - nothing in FreeNAS depends on it.

To install it on versions 11 or higher, until version 12.0-U1 of TrueNAS that includes it as default, follow these steps.

  1. Enable the FreeBSD repo first:

    If you are using FreeNAS v11.2 or higher, you also have to disable the local package repository to avoid an issue in that particular release and that may affect later versions(opens new window) before running pkg install:

  2. Create a temporary directory and move into it:

  3. Fetch the required packages. A directory All will be created and you will find the packages with their current versions under there:

  4. Add the downloaded packages, without their dependencies:

    The versions reported here are just the current version and they maybe different in your installation.

  5. Revert the repos to their original settings to avoid surprises down the road. The second command should be run just if you disabled the local repo in step 1:

    A restart of the VM will perform a reset of these files to their original settings too.

  6. Once the package is installed, you need to tell FreeNAS to start the xe-daemon process when starting:

    1. Go to Tasks -> Init/Shutdown Script
    2. Create a new task with the following settings:
      • Type: Command
      • Command: /usr/local/sbin/xe-daemon -p /var/run/xe-daemon.pid &
      • When: Pre Init
      • Enabled: Checked

  7. Reboot. If you do not plan to reboot the VM, you can start the daemon manually running the command /usr/local/sbin/xe-daemon -p /var/run/xe-daemon.pid &. After you'll see a FreeBSD icon in your VM list on Xen Orchestra, and you can restart/shutdown the VM properly from the Web UI.

# Windows

Windows guests need both the device drivers and the management agent.

  • The device drivers bring optimized I/O performances.
  • The management agent brings more manageability of the VM from XCP-ng, and guest metrics reporting to the host.

# Citrix tools vs XCP-ng tools

There exists two different set of tools that you can use on your VMs: the official tools from Citrix Hypervisor, or the fully open-source tools from XCP-ng. Both work well. The important point is not to mix them in the same VM.

Citrix tools:

  • ➕ Benefit from all the testing by Citrix QA team.
  • ➕ The drivers can be updated through Windows Update.
  • ➖ Proprietary, closed-source.

XCP-ng tools:

  • ➕ Fully open-source.
  • ➕ Maintained by the XCP-ng project.
  • ➕ ➖ The sources for the drivers are from the Xen project directly, without additional Citrix patches. This is good, but it may be that in some specific situations Citrix drivers behave better (None known at the moment).
  • ➖ The sources for the management agent are older than that of Citrix (they have stopped updating GitHub a while ago).
  • ➖ Maintained by one overloaded community member until Vates finds a developer to hire or contract with in order to maintain them more efficiently.
  • ➖ Won't transparently replace existing Citrix tools. You need to remove Citrix tools first if they are present, in order to install XCP-ng tools.

It's now up to you to choose.

# XCP-ng Windows Guest Tools

Drivers built by the XCP-ng community.

Download: https://github.com/xcp-ng/win-pv-drivers/releases(opens new window)

Stability and testing status: Windows guest tools community testing(opens new window).

# How to know if tools are already installed and working

The VM needs to be running for this test.

# From Xen Orchestra
  • Management agent + device drivers: XO displays 'Hardware virtualization with paravirtualization drivers enabled (PVHVM)'
  • Device drivers alone: Xen Orchestra is currently (2020-03-30) unable to detect if the device drivers are installed if the management agent is not installed either. See https://github.com/vatesfr/xen-orchestra/issues/4783(opens new window). If it displays 'No tools detected', it is still possible that the device drivers are present.
# From command line
  • Device drivers: xe vm-param-get param-name=PV-drivers-detected uuid={VM-UUID}
  • Management agent: xe vm-param-get param-name=PV-drivers-version uuid={VM-UUID} (ok if not empty)

# Installing on fresh installed Windows

# Prerequisite: Disable 'Windows Update tools'

The first step, before the VM creation and first start, is to make sure than Windows Update is not going to install Citrix tools automatically at first boot. This behaviour is governed by the 'Windows Update tools' parameter in a VMs advanced view. It must be off.

Before creating the VM:

  • Make sure you are not creating it from a custom template than has the 'Windows Update tools enabled.
  • ⚠️ Do not create it from XCP-ng Center. XCP-ng Center automatically enables that option when the license allows it (and in XCP-ng the license always allows it...). This behaviour may be modified in the future.

Before starting the VM:

  • Check the value of 'Windows Update tools' in the Advanced tab of your VM in Xen Orchestra. Must be off.

If you already started the VM with the option on, then the Citrix drivers have been installed automatically. Restart from scratch or see below how to remove them.

Tip: you can also check the value of the parameter from the command line.

True means that it's active, False that it isn't. It needs to be False.

# Install the XCP-ng drivers
  1. snapshot before just in case
  2. unpack the ZIP file
  3. start setup.exe
  4. follow the install wizard

Note: Restart can take a while if your windows is currently updating. Restart only occurs after windows has the updates finished.

  1. after restart one of two messages should pop up
    • request for restart <- just restart!
    • Management Agent installed successfully <- enjoy 😃

# Upgrade from Citrix ®️ XenServer ®️ client tools

Our installer is not able currently to cleanly uninstall Citrix tools. Citrix tools' uninstaller itself isn't either: it leaves various things behind.

So we need to perform a complete manual clean-up of the tools:

  • either entirely manually
  • or using the experimental PowerShell script contributed by one of our users at https://github.com/siodor/win-tools-cleanup(opens new window)

⚠️ In any case, first disable 'Windows Update tools' for the VM (Xen Orchestra, advanced tab) and reboot it.

Following is the manual process.

# The confident option

You can try a simple process first with some chances of success.

  1. Make a snapshot so you can rollback. Windows can get unstable/unbootable if things go wrong.
  2. Uninstall Citrix ®️ XenServer ®️ Client Tools
  3. Reboot
  4. Uninstall XenServer PV-Drivers in Device Manager in following order (reboots may be needed):
    • XenServer PV Network Device (one ore more Devices)
    • XenServer PV Storage Host Adapter
    • XenServer PV Network Class
    • XenServer Interface
    • XenServer PV Bus (c000) (if present)
    • XenServer PV Bus (0002) or XenServer PV Bus (0001)
  5. Reboot
  6. Check that you see this unknown device in Device Manager:
    • SCSI-Controller - PCI-Device ID 5853:0002
  7. Unpack ZIP file
  8. Start setup.exe
  9. Follow the install wizard

Note: Restart can take a while if your windows is currently updating. Restart only occurs after windows has the updates finished.

# The nuclear option

If the confident option above didn't yield the expected results, then we switch to a more aggressive attitude towards the old tools.

TIP

What follows works in many cases, but some users occasionally still meet the following issues: XCP-ng tools not installing (but Citrix tools install well, so that is a solution to have working tools), and occasional BSODs in some cases or versions of Windows.

Through many tests, a user came up with a similar yet slightly different procedure that allowed them to avoid Blue Screens Of Death in their situation: https://xcp-ng.org/forum/post/27602.

Help is welcome to help us reconcile both procedures into one.

  • Follow the steps 0 to 4 of the 'confident option' above if not done yet.
  • Follow this (ignore steps 6 and 7, do not try to install the tools yet) https://support.citrix.com/article/CTX215427(opens new window)
  • Now open regedit and go to HKLMSYSTEMCurrentControlSetServices and delete entries for all xen* services.
  • In regedit, also go to HKLMSOFTWAREMicrosoftWindowsCurrentVersionDIFxDriverStore and remove ONLY xennet* xenvif*
  • Go to C:WindowsSystem32 and remove: (you may not have all these)
    • xenbus_coinst*.dll
    • xenvbd_coinst*.dll
    • liteagent.exe
  • Now go to C:WindowsSystem32drivers and remove any files named xen*
  • Go to C:Windowssystem32DriverStoreFileRepository and remove xennet* and Xenvif* directories.
  • Open the Device Manager and Click View --> Show Hidden Devices. Select Other Devices and Right click on XENBUS VIF and select uninstall. If it asks to delete the driver, check yes. Do this for any xen related thing you see in device manager. Also do the same for any unknown devices.
  • Lastly, reboot the VM. You should now hopefully be able to install xen tools regularly.

Note: Also have a look at our Troubleshooting Guide - Windows PV-Tools.

# VMs with INACCESSIBLE_BOOT_DEVICE error

You can try to manually inject the missing drivers in recovery mode.

  • Get the 'Drivers' folder from the XCP Tools installation path (C:PROGRAM FILES...) - from another VM or install the tools somewhere else to get it.
  • Create an ISO-Image containing the 'Drivers' folder (see http://imgburn.com(opens new window)) and mount that ISO-Image to your VM
  • Boot to recovery mode and use the command line and the tool 'dism' (see Microsoft Docs(opens new window)) to inject the drivers (specifically the xenbus and xenvbd drivers) - watch out for the drive letter of the Windows installation and the CD-Drive ('D' and 'E' in the following example):

# Using the Windows guest tools from Citrix

Tools from Citrix are not included in the guest tools ISO distributed with XCP-ng for legal reasons.

# A reminder

As written above:

  • The device drivers bring optimized I/O performances.
  • The management agent brings more manageability of the VM from XCP-ng, and guest metrics reporting to the host.

Download Citrix SCSI & RAID Devices Driver

# Management agent + device drivers

The only way to get the management agent is from Citrix. It can be freely downloaded from the Citrix Hypervisor download page(opens new window), provided you create an account on their site. Name of the item: 'Citrix VM Tools for Windows'. The installer will install both the management agent and the device drivers.

# Automated installation via Windows Update: device drivers alone

Download Citrix Scsi & Raid Devices Drivers

If you are using Xen Orchestra, you can switch the 'Windows Update tools' advanced parameter on from the 'Advanced' tab of the VM view. This will install the device drivers automatically at next reboot ⚠️ but not the management agent which still needs to be installed from Citrix tools' installer.

... So the 'Windows Update tools' option is not a complete solution if you need the guest metrics from the management agent. However it may be a convenient way to get future driver updates if you wish so.

# Switching from XCP-ng tools to Citrix tools

If your VM already has XCP-ng tools and you wish to switch to Citrix tools, then you need to do the same kind of clean-up as described higher in this document for the opposite situation.

# Windows

The XCP-ng team is looking for help in improving the guest tools installer, build process, and clean-up tools.

Device drivers improve sound, graphics, networking, and storage performance. If you perform a custom VMware Tools installation or reinstallation, you can choose which drivers to install.

The set of drivers that are installed when you install VMware Tools depends on the guest operating system and the VMware product. For detailed information about the features or functionality that these drivers enable, including configuration requirements, best practices, and performance, see the documentation for your VMware product. The following device drivers can be included with VMware Tools.

SVGA driver
This virtual driver enables 32-bit displays, high display resolution, and faster graphics performance. When you install VMware Tools, a virtual SVGA driver replaces the default VGA driver, which allows for only 640 X 480 resolution and 16-color graphics.

On Windows guest operating systems whose operating system is Windows Vista or later, the VMware SVGA 3D (Microsoft - WDDM) driver is installed. This driver provides the same base functionality as the SVGA driver, and it adds Windows Aero support.

Paravirtual SCSI driver
When you create a virtual machine, if you specify that you want the virtual machine to use a BusLogic adapter, the guest operating system uses the SCSI driver that VMware Tools provides. A VMware Paravirtual SCSI driver is included for use with Paravirtual SCSI devices. This driver for VMware Paravirtual SCSI adapters enhances the performance of some virtualized applications. Drivers for other storage adapters are either bundled with the operating system, or they are available from third-party vendors.

For example, Windows Server 2008 defaults to LSI Logic SAS, which provides the best performance for that operating system. In this case, the LSI Logic SAS driver provided by the operating system is used.

VMware supplies a special SCSI driver for virtual machines that are configured to use the BusLogic virtual SCSI adapter. Virtual machines do not need this driver if they do not need to access any SCSI devices or if they are configured to use the LSI Logic virtual SCSI adapter.

The driver is included as part of the VMware Tools package or comes bundled with VMware ESX/ ESXi. It is available on the host as a floppy image at /vmimages/floppies/vmscsi.flp. The driver can be used in Windows XP, Windows Server 2003, or Windows 2000.

VMXNet NIC drivers
The VMXNET and VMXNET3 networking drivers improve network performance. The set of drivers that are used depends on how you configure device settings for the virtual machine. Search the VMware Knowledge Base for information on which guest operating systems support these drivers.

When you install VMware Tools, a VMXNET NIC driver replaces the default vlance driver.

Mouse driver
The virtual mouse driver improves mouse performance. This driver is required if you use third-party tools such as Microsoft Terminal Services.
Audio driver
Driver
This sound driver is required for 64-bit Windows XP, 32-bit Windows Server 2003, 64-bit Windows Server 2003, Windows Server 2008, Windows 7, and Windows Vista guest operating systems.
Guest Introspection Driver
The two Guest Introspection drivers are the File Introspection driver and the Network Introspection driver. You can install the two drivers separately. When you install VMware Tools, by default, the Guest Introspection drivers are not installed.
  • File Introspection Driver: The File Introspection driver uses the hypervisor to perform antivirus scans without a bulky agent. This strategy avoids resource bottlenecks and optimizes memory use.
  • Network Introspection Driver: The Network Introspection driver supports NSX for vSphere Activity Monitoring.
Memory control driver
This driver is required for memory ballooning and is recommended if you use VMware vSphere. Excluding this driver hinders the memory management capabilities of the virtual machine in a vSphere deployment.
Modules and drivers that support making automatic backups of virtual machines
If the guest operating system is Windows Vista, Windows Server 2003, or other newer Windows operating systems, a Volume Shadow Copy Services (VSS) module is installed. For other, earlier Windows operating systems, the Filesystem Sync driver is installed. These modules allow external third-party back up software that is integrated with vSphere to create application-consistent snapshots. During the snapshot process, certain processes are paused and virtual machine disks are quiesced. The modules also support quiescing snapshot on Linux OS
VMCI and VMCI Sockets drivers
The Virtual Machine Communication Interface driver supports fast and efficient communication between virtual machines and the hosts they run on. Developers can write client-server applications to the VMCI Sock (vsock) interface to make use of the VMCI virtual device.
VMware drivers for Linux
The drivers for Linux are automatically installed during your operating system installation, eliminating the need to separately install drivers after OS installation. VMware actively maintains the source code for VMware Paravirtual drivers, VMXNET, VMXNET3 and kernel modules, and any Linux distributions creating new OS releases automatically include the latest VMware drivers.

Do not delete or replace existing inbox drivers for Linux that are distributed by your OS vendors. Deleting or replacing these drivers might cause conflict with future updates to the drivers. Contact your OS vendor or OS community for availability of specific updates to drivers.

See http://kb.vmware.com/kb/2073804 for information about availability, maintenance, and support policy for inbox drivers for Linux.

VMHGFS driver

If you use Workstation or Fusion, you can install the Shared Folders component. With Shared Folders, you can easily share files among virtual machines and the host computer. The VMHGFS driver is a file system redirector that allows file system redirection from the guest operating system to the host file system. This driver is the client component of the Shared Folders feature and provides an easy to use alternative to NFS and CIFS file sharing that does not rely on the network. For Linux distributions with kernel version 3.10 and later, a new FUSE based Shared Folders client is used as a replacement for the kernel mode client.
