Notes and Known Issues
VMware
• PCI I/O hole may need to be changed for Windows 64-bit VMs.
Windows 64-bit VMs may require that you edit the VM configuration file to
configure a larger PCI I/O hole for the GPU.
• Access Control Services is required on some switches.
Starting with ESX 5.0 Update 1, Access Control Services (ACS) is required on any
switches in the PCIe hierarchy above a PCIe device that is to be used for
passthrough. If ACS is not present, ESX will not allow the device to be assigned
directly to a VM.
To allow assignment of devices below switches that do not support ACS, you can
disable the ACS check as follows:
esxcfg-advcfg -k true disableACSCheck
• Configuring passthrough to a Windows Server 2008R2 VM.
The VMware WDDM driver must be manually installed on Windows Server 2008
R2.
Follow the steps provided at http://communities.vmware.com/message/
1423263#1425288 .
• MSI translation must be disabled.
Blue-screen crashes may occur on VMs with assigned GPUs if MSI is initially
enabled for passthrough devices.
To avoid this issue, disable MSI translation by setting
pciPassthru0.msiEnabled =
"FALSE"
in the VM’s VMX file.
Citrix Xenserver
• XenServer 6.1 workaround for 64-bit MMIO failures on PCI passthrough.
Dom0 kernel may relocate GPU BARs to an invalid location immediately beyond
the end of physical RAM. There are two workaround options to address this
condition:
Workaround option #1: Add ‘
pci=use_crs ’ to the kernel parameters by running the
following command in Dom0:
/opt/xensource/libexec/xen-cmdline --set-dom0 pci=use_crs
