[PATCH 0/1] Add "Group Identifier" to virtio PCI capabilities.

[Venu Busireddy <venu.busireddy@oracle.com>]

During live migration involving passthrough devices, the guest needs
to know which virtio device will be a fail-over device for a given
passthrough device.

Extending the virtio specification with a new "Group Identifier"
capability allows qemu to set up the grouping at the time the guest
is created. The "Group Identifier" can be as simple as a number, or an
UUID. The driver can use the group identifier to pair the virtio device
with the passthrough device. The passthrough device can contain the
group identifier in the PCIe bridge to which it is attached.

  Add "Group Identifier" to virtio PCI capabilities.
