[libvirt] [PATCH 1/3] qemu: Add vhost-user-scsi/blk support
Li Feng
fengli at smartx.com
Mon Sep 30 06:54:20 UTC 2019
Vhost-user-scsi and vhost-user-blk is supported in Qemu, this patch add
support in libvirt.
Hotplug is also support here.
Usage like this:
<vhost-user-scsi-pci type='unix'>
<source type='bind' path='/tmp/unix/vhost-scsi.0'/>
</vhost-user-scsi-pci>
<vhost-user-blk-pci type='unix'>
<source type='bind' path='/tmp/unix/vhost-blk.0'/>
</vhost-user-blk-pci>
