Streaming Linux target devices 编辑

This article provides information about streaming Linux target devices. Using the Linux streaming feature with Citrix Provisioning, you can provision Linux virtual desktops in the Citrix Virtual Apps and Desktops environment.

You can use UEFI boot with Citrix Provisioning version 2106 and later.

Using the Linux streaming feature with Citrix Provisioning, you can provision Linux virtual desktops in the Citrix Virtual Apps and Desktops environment. For more information about the Linux streaming feature, see Use Citrix Provisioning to create Linux VMs.

Important:

We recommend that you use the most recent installation package of Citrix Provisioning. Use the package based on your Linux distribution. Citrix Provisioning Server 2109 or later is required to use Linux streaming agent 2109 and later.

Consider the following when provisioning Linux target devices:

• When you use Citrix Provisioning to stream Linux target devices, create a separate boot partition on the single shared-disk image so that the provisioned devices can boot as expected.
• Sometimes, the client drive cannot be mapped to a provisioned Linux VM session. To resolve this issue, halt the CDM service using service ctxcdm stop, before installing the Citrix Provisioning target device, then run the pvs-imager command to convert it.
• Linux streaming only supports Winbind as the tool for joining a Windows domain. Winbind provided by Samba 4.5 and newer is supported, including older releases.
• When you enable RAM cache for the Linux device, set the cache size to 8 MB (the minimum value). Linux uses as much RAM as necessary, including all available memory, for the write cache. The amount specified in the console is the amount reserved up front. Citrix recommends that you reserve as little as possible, which effectively allows Linux to manage memory usage.
• The target device name in the Citrix Provisioning imager UI typically defaults to im\_localhost. This value must be changed when you create more than one vDisk. Using the same target device name causes the imager command to fail.
• Installation (and subsequent updates) must be done in super user mode. There are two ways to install as a super user:
  • Enter user mode in a terminal using the su command.
  • Enter sudo before the command. For example, sudo yum install tdb-tools; enter sudo for every command.
• The Linux client’s system clock must be synchronized by using the active directory controller.
• VMM is not supported.
• The write cache drive must have the label PVS_Cache for it to be used as a write cache. The entire partition is used.
• English localizations are displayed on non-English installations.
• SE Linux is not supported.
• Targets running on Citrix Hypervisor must run in HVM mode.
• After booting a Linux target device, a warning message might display indicating a SE Linux Alert Browser.

• The following Linux distributions are supported:

  • Ubuntu 22.04
  • Ubuntu 20.04
  • Ubuntu 18.04
  • RHEL 8.6
  • RHEL 8.4
  • RHEL 7.9
  • Rocky Linux 8.6
  • SUSE 15.3
• Two streamed Ubuntu 18.04 or Ubuntu 20.04 VMs hosted on ESXi get the same IP address through DHCP. To resolve this issue, configure the VM to use the MAC address as a unique ID to retrieve an IP address through DHCP.
• On Ubuntu 18.04, when installing the installation package an error may appear: dracut-install: Failed to find module ‘crc32c’. This is a known issue of Ubuntu 18.04. To resolve it, comment add_drivers+=”crc32c” in /etc/dracut.conf.d/10-debian.conf and reinstall the package.
• Create a vDisk using UEFI boot from a master VM using UEFI boot.

Installation

To install the Linux Streaming component, you must be logged in while an administrator. If installing, consider that the following commands must be issued in a root shell, or by using sudo privileges.

Install the linux streaming package

For Ubuntu 22.04 distributions:

sudo dpkg -i pvs_<version>_ubuntu22.04_amd64.deb
sudo apt-get -yf install
