[libvirt] [PATCH v2 2/9] qemu: Only setup vhost if virtType == "kvm"

[Cole Robinson]

vhost only works in KVM mode at the moment, and is infact compiled
out if the emulator is built for non-native architecture. While it
may work at some point in the future for plain qemu, for now it's
just noise on the command line (and which contributes to arm cli
breakage).
