Hi all, maybe someone can help me with my KVM related questions. At the moment we want to add cpu flags to the standard qemu64 CPU-Model in a testcluster.
For this we tried the following configuration: guest.cpu.mode=custom guest.cpu.model=qemu64 guest.cpu.features=sse4.2 sse4.1 But ended up with the following error message: org.libvirt.LibvirtException: unsupported configuration: guest and host CPU are not compatible: Host CPU does not provide required features: svm When we use kvm64 instead of qemu64 the start of the vm is working and the needed flags are available. Has someone experience in using kvm64 over qemu64 and are there some drawbacks with it? Also I guess the standard CPU-Model which comes from guest.cpu.mode=host-model is qemu64. Why is it working with mode host-model and not with custom. Is there some libvirt magic involved?
