Subject Re: Need to ask for help again (Migration in cloudstack)
Date Tue, 05 Sep 2017 13:27:01 GMT
Hi Dimitriy,

I wrote the PR for the live migration in cloudstack (PR 1709). We're using
an older version than upstream so it's hard for me to fix the integration
tests errors. All I can tell you, is that you should first configure
libvirt correctly for migration. You can play with it by manually running
virsh commands to initiate the migration. The networking part will not work
after the VM being on the other machine if down manually.
