Hello and thanks for you answer , I tried to enable post copy live migration on compute node, restarted the nova compute serviceon compute nodes but when I try to live migrate a vm I have the same issue: I loose a lot of packets.If I try with an instance which have a daemon which ping the default gateway, the live migration works fine and I do not loose packets.I think this is a big issue.I tried with rocky and queens with iptables_hybrid and both have the issue.:-(Ignazio
