foo at VMHOST:~$ sudo ovs-vsctl show
   Bridge "vbridge0"
       Port "vnet0"
           tag: 2
           Interface "vnet0"
       Port "vbond0"
           Interface "eth2"
           Interface "eth1"
       Port "vbridge0"
           Interface "vbridge0"
               type: internal
   ovs_version: "2.5.2"

I've tried changing MTU parameters on my internal vbridge0 interface:

sudo ovs-vsctl set interface vbridge0 mtu=1520

This command runs, but does nothing to the MTU of my internal bridge

There's supposed to be a separate command:
ovs-vsctl set int vbridge0 mtu_request=1520

<column name="mtu_request"
              type='{"type": "integer", "minInteger": 1}'>
          Requested MTU (Maximum Transmission Unit) for the interface. A
          can fill this column to change the MTU of an interface.

I get this back when running the command:
ovs-vsctl: Interface does not contain a column whose name matches

What am I doing wrong?
All other interfaces in my bridge for example the eth1 and eth2 of my
and the vnet0 being created by libvirt is setting itself to 1520 by way of
the guest's /etc/network/interfaces file and shows 1520 values when I run
* list interface vnet0 command.

is the mtu_request= a deprecated option?
