Original Document release

PCI Passthrough does not function for the HP Broadcom NICs listed under Platforms Affected and configured on HP virtualization hosts running the following versions of Linux:

  • Red Hat Enterprise Linux 5 Update 8
  • Red Hat Enterprise Linux 5 Update 9
  • Red Hat Enterprise Linux 6 Update 2
  • Red Hat Enterprise Linux 6 Update 3
  • Red Hat Enterprise Linux 6 Update 4
  • Red Hat Enterprise Linux 6 Update 5
  • Red Hat Enterprise Linux 6 Update 6
  • Red Hat Enterprise Linux 7 Update 0
  • SUSE Linux Enterprise Server 11 Service Pack 2
  • SUSE Linux Enterprise Server 11 Service Pack 3
  • SUSE Linux Enterprise Server 12
  • SUSE Linux Enterprise Server 12 Service Pack 1

The KVM hypervisor supports attaching PCI devices on the host system to virtualized guests. PCI Passthrough, which allows guests to have exclusive access to PCI devices, does not function for all HP Broadcom NICs.

When this occurs, the assignment of the HP Broadcom NICs to the virtualized guests succeeds, but the guests will not come up after the next reboot.

This is not specific to HP. This occurs because Broadcom has not yet implemented this feature.

SCOPE

Any HP ProLiant server and HP Broadcom NIC listed under Platforms Affected running any of the following versions of Linux as virtualization hosts:

  • Red Hat Enterprise Linux 5 Update 8
  • Red Hat Enterprise Linux 5 Update 9
  • Red Hat Enterprise Linux 6 Update 2
  • Red Hat Enterprise Linux 6 Update 3
  • Red Hat Enterprise Linux 6 Update 4
  • Red Hat Enterprise Linux 6 Update 5
  • Red Hat Enterprise Linux 6 Update 6
  • Red Hat Enterprise Linux 7 Update 0
  • SUSE Linux Enterprise Server 11 Service Pack 2
  • SUSE Linux Enterprise Server 11 Service Pack 3
  • SUSE Linux Enterprise Server 12
  • SUSE Linux Enterprise Server 12 Service Pack 1

RESOLUTION

For HP Broadcom NICs that support Single Root I/O Virtualization (SR-IOV), virtual functions can be created on the virtualization hosts and assigned to the virtualized guests.

Broadcom is working on implementing support for PCI Passthrough for NICs. This advisory will be updated when more information becomes available.
