Comment 9 for bug 1458119

I found this bug by searching related bug fix from https://bugs.launchpad.net/mos/+bug/1457123, in our Openstack environment, fuel 6.0/juno, 3 controller HA, when we restarted the master controller node, there were some VM instances can't reach the external network(xshell session lost connect), internal network was not interrupted.
does the master fix available for juno?
I will test it soon.
