Comment 1 for bug 1747709

After some digging on my local devstack VM I found that problem is happend every time when I do hard reboot of VM - after hard reboot I can't ssh to it.
In attachement I paste dump of "good" OF rules - those are rules from before hard reboot when VM is accessible and "bad" OF rules - those are rules from after hard reboot when VM is not accessible anymore.
Restart of ovs L2 agent fixes issue and VM is accessible again.
