Hi Peter, The information you provided is not enough to find out the root cause. Could you share more information ?
cloudstack version os distribution and version network device name on source host and destination host output of `brctl show` or `bridge link` on source host and destination host logs in /var/log/cloudstack/agent/agent.log on source host and destination host. I guess the network device name on hosts are different. -Wei On Wed, 24 Nov 2021 at 09:31, Peter Stine <peter.st...@granddial.com.invalid> wrote: > Good afternoon everyone, > > I have gotten my cloudstack running, but I am unable to live migrate any > of my VMs. I get an error like this: "Exception during migrate: > org.libvirt.LibvirtException: Cannot get interface MTU on > 'brenp3s0f0-3128': No such device" > I have tried using an L2, isolated, and shared network.
