Subject: qemu: automatically set model type='virtio' for interface type='vhostuser'
X-Git-Tag: v11.1.0-rc1~63
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c4746418d7e952888c0989db3a5c723d888fc32d;p=thirdparty%2Flibvirt.git

qemu: automatically set model type='virtio' for interface type='vhostuser'

Both vdpa and vhostuser require that the guest device be virtio, and
for interface type='vdpa', we already set <model type='virtio'/> if it
is unspecified in the input XML, so let's be just as courteous for
interface type='vhostuser'.
