Hi<div><br></div><div>This could be achieved by adding the ifdown command in the clean script of the 802.1q driver. The core functionality is provided by HostManaged.rb. If you take a look at the code, maybe you can add a method similar to</div>
<div>the activate one that iterates over the VLAN devs and execute an ip link set <dev> down. Note that you can only set down the interface if there are no other VM using it (so you would need to query the bridge). Bridge, devices and VLAN IDs can be easily obtained as shown in the activate method of the HostManaged class.</div>
