[libvirt] [PATCH 1/2] qemu: add ibmvscsi controller model

Fri Jan 13 12:23:55 UTC 2012
KVM will be able to use a PCI SCSI controller even on POWER. Let
the user specify the vSCSI controller by other means than a default.
After this patch, the QEMU driver will actually look at the model
and reject anything but auto, lsilogic and ibmvscsi.
