[libvirt] [PATCH 08/17] qemu: Introduce qemuDomainDeviceDefValidateControllerSCSI

Tue Dec 5 01:38:58 UTC 2017
Move SCSI validation from qemu_command into qemu_domain.
This includes the @model reset/check when the controller
model hasn't yet been set. While at it modify the switch
to account for all virDomainControllerModelSCSI types
rather than using the default label.
Rename/reorder the args in qemuCheckSCSIControllerIOThreads
to match the caller and also remove the unnecessary model
check as well as fixing up the comments to remove the previously
removed qemuCaps arg.
