Libvirt does not model every aspect of each CPU so the guest CPU will not match the host CPU exactly.
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
host-modelhost-passthrough With this mode, the CPU visible to the guest should be exactly the same as the host CPU even in the aspects that libvirt does not understand.
