It looks like you want to add : <controller type='scsi' index='0' model='virtio-scsi'/> Then in change that <target line to <target dev='sda' bus='scsi'/> Problem is this will change the disk device node in the guest from vda to sda, so could cause mounting problems. - Cole _______________________________________________ virt mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/virt
