I'm a bit confused about that HOWTO since CMOV has nothing todo with CMPXCHG8B. And your CPUID states that the host _has_ CMOV. It is also possible that the installer detects VIA CPUs and expects some other feature is not emulated by the VM, for example look at the CPUID extended attributes at index 0x80000005 and 0x80000006.
