When creating cgroups for vcpu and emulator threads whilst starting a domain, we explicitly skip creating those cgroups in case priv->cgroup is NULL (cgroups not supported) because SetAffinity() serves the same purpose. If the host supports only some cgroups (the ones we need are either unmounted or disabled in qemu.conf), we error out with weird message even though we could continue starting the domain.
