Tried in <cpu> section: <feature policy='disable' name='kvm_steal_time'/> but that doesn't work. Also, couldn't find any related information in libvirt documentation. Google...

Ok libvirt can't get this value, but does it possible if i know cpu stats of domain and host info (i don't know which =)) determine for specific domain does it possible have steal time or not? -- Vasiliy Tolstov,
