<div><br></div><div>When I create a snapshot from a VM that is running with a QCOW2 image file and I revert that snapshot, the vnet interface for that VM in opennebula misses the vlan-tag that puts the traffic in the correct vlan. When I manually set the tag for the vnet interface again (ovs-vsctl set port vnet1 tag=206) , the vm works fine again. See the before and after the "revert snapshot" details below. The vnet1 interface is the interface connected to the VM that I reverted the snapshot on. </div>
