The latest qemu has support the vhost-user-scsi and vhost-user-blk backend for
better performance.
This patch let the libvirt could manage the vhost-user disks.
Usage in xml like this:
<vhost-user-blk-pci type='unix'>
<source type='bind' path='/tmp/vhost-blk.sock'>
<reconnect enabled='yes' timeout='5' />
</source>
<queue num='4'/>
</vhost-user-blk-pci>
