Xen VGA Passthrough Tested Adapters

We only recently started collecting this information and rely on you to let us know how it works for you!

List of tested graphics adapters for Xen VGA Passthrough

Please send an email to xen-devel or xen-users with all the details about your VGA graphics passthru experience. If you are confident that your adaptor works, feel free to just add it to this page.

Please include the following details in the email:

• Xen version
• Dom0 kernel version, and if it's pvops or xenlinux based
• "lspci" output for the graphics card to get the PCI IDs and model information
• Did you passthru all the PCI IDs or just one?
• Was it primary or secondary graphics adapter?
• Motherboard vendor/model and BIOS version.
• Guest OS and driver version.
• How did it work.. did you have some issues?

Xen VGA graphics passthru has been tested to work with these graphics adapters:

Nvidia display adapters

Note that Nvidia officially supports only Quadro FX 3800, 4800 and 5800 for graphics passthrough usage (they've tested and verified their binary drivers for these graphics cards in combination with graphics passthrough).

In addition, Nvidia lists the following graphics adapters as "Multi-OS" capable: Quadro 6000, 5000, 4000, 2000. "Multi-OS" allows VGA passthrough to fully virtualized guests. Note: The Nvidia Quadro 600 is not supported.

GeForce 7 Series (7xxx), 8 Series 8xxx), 400 Series and 600 Series should work as primary adapter after patching MMIO BARs of gfx for 1:1 mapping. But this work only with Windows XP DomU, and only with specific drivers version (Jean David Techer Blog [1]). Most "non-Multi-OS" capable adapter won't work this way with Windows Vista/7/8.

Some GeForce adapters with the same chipset as Quadro Multi-OS capable adapters can be modified into their Quadro/Grid counterparts, and subsequently work with passthrough in domU. Reports of successful passthrough with modified cards include:

• GeForce GTX670/680/690 to Quadro GridK2 / K5000 (GK104) (Australian crazy guy [2]).
• GeForce GTS450 to Quadro 2000 (GF106) (See here for details on how to modify a GeForce 4xx card into an equivalent Quadro [3])
• GeForce GTX480 to Quadro 4000M (GF104)
• GeForce GTX470 to Quadro 5000 (GF100)
• GeForce GTX480 to Quadro 6000 (GF100)

User reported working adapters:

• nVidia Quadro 2000, as secondary display adapter, Linux Mint 13 dom0, Xen 4.1.2, Windows 7 guest with Nvidia driver 305.93.
• nVidia G92 (GeForce 8800 GTS 512), as primary adapter, Xen 4.0.0-rc8, pvops xen/stable-2.6.32.x dom0, Linux HVM guest with nv driver.
• nVidia GTS450 modified into a Quadro 2000 (GF106), secondary passthrough, EL6, 4.2.x, 4.3.x, XP64 domU drivers ~295+
• nVidia GTX460 modified into a Quadro 4000M (GF104), Windows 7 32-bit guest
• nVidia GTS470 modified into a Quadro 5000 (GF100), secondary passthrough, EL6, 4.2.x, 4.3.x, XP64 domU drivers ~295+
• nVidia GTS480 modified into a Quadro 6000 (GF100), secondary passthrough, EL6, 4.2.x, 4.3.x, XP64 domU drivers ~295+
• nVidia GTX670, GTX680 modified into a Grid K2 or Quadro K5000 (GK104), secondary passthrough, EL6, 4.2.x, 4.3.x, XP64 domU drivers ~300+

domU reboots reportedly work seamlessly for most users of the Nvidia Fermi and Kepler GPUs listed above, both with genuine Quadros and GeForce cards modified into Quadros/Grids.

User reported _NOT_ working adapters:

• nVidia Quadro NVS 295, Xen 4.2.1, Ubuntu 12.04 LTS dom0, xen-pciback.hide, Win Vista x64 HVM, either as primary or secondary adapter. As secondary adapter VM start, but windows stays with the SDL display. As primary adapter VM don't start, even after patching for identity memory I/O regions mapping and inserting VGA-rom in Xen 4.2.1.
• nVidia GeForce GTX580 modified to Quadro 7000 (GF110) (Note: Quadro 7000 is not listed as MultiOS compatible)

ATI/AMD display adapters

AMD sent patch enabling VGA passthrough on AMD/ATI Radeon/FirePro graphics adapters on 2010-10-07: http://lists.xensource.com/archives/html/xen-devel/2010-10/msg00284.html .

Remember to install the graphics drivers in the DomU first, before expecting secondary passthrough to work.

• Radeon 4850
• Radeon 4870
• FirePro V5700
• FirePro M5800

• AMD Radeon HD7970, Win7 HVM

There are certain user-reports that the Catalyst Control Center (ccc.exe) should be _not_ installed when installing the Catalyst Driver - for unknown reasons it may cause a BSOD. The GPU Driver itself works without problems when not installing CCC.

There are widespread reports of ATI/AMD cards causing major problems when the domU is rebooted, including severely degraded performance, domU crashes and complete host dom0 crashes.

User reported _NOT_ working adapters:

• ATI Radeon x1950, Xen 4.2.1, Ubuntu 12.04 LTS dom0, Win Vista x64 HVM, either as primary or secondary adapter.
