In 4.4, Can somebody explain, why use "OVSTunnelxxx" for GRE tunnel device, and
not "cloudbr1" ?
When create VM, this will result an exception:

I found code as below:
public InterfaceDef plug(NicTO nic, String guestOsType)
} else if (nic.getBroadcastType() == Networks.BroadcastDomainType.Vswitch) {
String vnetId =
Networks.BroadcastDomainType.getValue(nic.getBroadcastUri());
String brName = "OVSTunnel" + vnetId;
