Just last week I wrote to this list about DNS issues kvm installed but it
never posted ( moderator denied ?? ). On both RedHat and Ubuntu from what
I've seen kvm/virt  listens on 192.168.122.1:53 and even if you provision
samba with --host-ip samba still wants to use the kvm dns IP versus the
real IP address and all things DNS fails. I removed all the kvm/virt
packages and everything is happy now after 30 minutes of fail... fail..
ahhh. so that is why. :)
