Hi guys, Sorry I thought I'd start a new thread for this issue, as it's now a different problem from my original post "Migration failed due to Error: novm" After my VM failed to migrate from one host to the other my VM was still responsive but showed that it was powered off in oVirt, so I logged into the console on the Linux guest and rebooted it, which appears to have resolve the issue as it now shows up on my engine as on, but I've just noticed now I've got two VM instances running on two separate hosts... On host 10.0.2.22 15407 ?

By doing a tcpdump I can see traffic from the users passing to both VM's so I'm very worried. Please could someone assist me please, I'm desperate! Thank you!! Regards. Neil Wilson.
