##### SUMMARY
<!-- Explain the problem/feature briefly -->
Guest vms do not get public dns servers (from zone "public dns" setting) in
dhcp offer
As result vr ip is only ip in resolv.conf file in guest vm
VPC restart with "Cleanup" does not help
VR has dnsmasq as dns server, which resolvs guest vms hostnames, but not public
domains
if I try to check for example (from guest vm)
