[libvirt] [PATCH v2 08/31] qemu: Don't return unusable virttype in domain capabilities
If a user asked for a KVM domain capabilities when KVM is not available,
we would happily return data we got when probing through TCG and
pretended they were relevant for KVM. Let's just report KVM is not
supported to avoid confusion.
