[libvirt] cannot start a qemu64 model on an Intel host

If I specify <cpu match="exact"> <model>qemu64</model> </cpu> according to the new cpu schema, I get error: internal error guest CPU is not compatible with host CPU because qemu64 supports svm, and my host does not. However, the error remains when I explicitly ask to disable svm with <feature policy="disable" name="svm"/> I am not sure if this is a bug or an intended feature, but I'd expect cpu_disable taken into account when doing x86ModelCompare(host_model, cpu_require) Regards, Dan.
