[libvirt-users] LibVirt CPU problem

Hi, I´m testing to start a KVM-VM with different CPU settings and I get an weird error when I use the parameter: <cpu mode='host-model'> !! I have a AMD Opteron 4280 CPU, but in the VM, proc/cpuinfo shows me, that I´m using Intel core2duo cpu model T7700 and in the flag-line of proc/cpu the system is listing the svm-flag of AMD?!?! If I use <cpu mode='host-passthrough'> I get the right CPU-model listed in the VM! Anyone an idea why I get the wrong information with host-model? BTW some further information about used versions: LibVirt version is 0.9.12 qemu-kvm 1.0 Kernel 3.3.2 Cheers, Mike
