The bug is reproduced on Mellanox enabled environments with some VM images (it seems CirrOS is not affected but Ubuntu is).
DHCP lease time in Fuel 6.0 is 60 seconds.
During a Controller failover Dnsmasq can start up to 10 minutes. That's why VMs loose IP addresses and connectivity. As a workaround, this patch can be applied https://review.openstack.org/#/c/143996/
Taking into account all above I decrease the Bug importance to High.
