[libvirt] [PATCH 0/2] qemu: add vhost-scsi-pci support
From: Nicholas Bellinger <nab(a)linux-iscsi.org>
Hi Daniel & Co,
The following is the patch series to add support for vhost-scsi-pci
from QEMU >= v1.5.x into libvirt. It includes proper support for
passing a pre-opened vhostfd into vhost-scsi, which is required in
order to properly support nova performing a device_add for adding
a individual vhost-scsi-pci WWPN endpoint -> SCSI controller.
The logic closely follows what vhost-net already does in order to
allow a child qemu process to interact with the vhost-scsi character
device for registering vhost memory, setting vhost-scsi endpoints,
etc.
This code has been tested using openstack nova volume-attach, using
a Juno v2 development head from 07192014.
Thank you,
--nab
