Right now, I found that Windows Failover Cluster needs SCSI-3 Persistent Reservation, I don't know where if virtio-scsi supports this, according to http://www.ovirt.org/Features/Virtio-SCSI I found this: limited flexibility: virtio-blk does not support all possible storage scenarios. For example, it does not allow SCSI passthrough or persistent reservations. In principle, virtio-scsi provides anything that the underlying SCSI target (be it physical storage, iSCSI or the in-kernel target) supports. virtio-blk does not support persistent reservations, but virtio-scsi may surpport. Another web page which archive mail lists http://www.spinics.net/lists/target-devel/msg01813.html, which request virtio-scsi to implement SPC-3 (persistent reservation) feature, but I can't found any more information about this.
