Re: [libvirt] [PATCH 2/3] qemu: Separate calls based on controller bus type

For systems without a PCI bus, attaching a SCSI controller fails: [root@xxxxxxxx ~]# cat controller.xml <controller type='scsi' model='virtio-scsi' index='0' /> [root@xxxxxxxx ~]# virsh attach-device guest01 controller.xml error: Failed to attach device from controller.xml error: XML error: No PCI buses available A similar problem occurs with the detach of a controller: [root@xxxxxxxx ~]# virsh detach-device guest01 controller.xml error: Failed to detach device from controller.xml error: operation failed: controller scsi:0 not found The qemuDomainXXtachPciControllerDevice routines made assumptions that any caller had a PCI bus. These routines now selectively calls PCI functions where necessary, and assigns the device information type to one appropriate for the bus in use.
