Hi All,
I have a situation where the port number associated with the tap interface of a
VM changes after the VM reboot.
1. My setup is I have a VM deployed in openstack.
2. VM is connected through tap interface to the openvswitch in compute node.
3. openvswitch is controlled by opendaylight controller.
Whenever the VM is rebooted the port number associated with the tap interface
changes in the openvswitch.
Is the above behavior normal ? or my openstack or opendaylight configuration
has got something to do with this behavior?
I have also observed the port numbers of all the tap interfaces in the
openvswitch changes when I restart the compute node.
By default, the port number will depend on the order the interfaces are added. If you
have stable tap interface names, you could look at populating "ofport_request"
column as described in the ovs-vswitchd.conf.db man page.
