Hello everyone,
After I do a live migration of a vm to another node in a 3 node cluster; I cannot connect to it using it's ip address from the original node (when migration is done the ping from the node to the vm stops responding).
Following is the /etc/network file which is the same for all the nodes (the network card names do differ):
auto lo
iface lo inet loopback
iface lo inet6 loopback
auto enp8s0
iface enp8s0 inet static

up route add -net <> netmask 255.255.255.224 gw <> dev enp8s0
