If that is the theory then it has failed to trickle through in practice. As 
you know i have reported a long list of usability problems with hardly a look. 
That list could be created by pretty much anyone spending a few minutes of 
getting a first impression with qemu-kvm.

So something is seriously wrong in KVM land, to pretty much anyone trying it 
for the first time. I have explained how i see the root cause of that, while 
you seem to suggest that there's nothing wrong to begin with. I guess we'll 
have to agree to disagree on that.

Thanks,
