Subject: [pve-devel] [PATCH qemu-server] copy conntrack information on migration
Date: Fri, 16 Oct 2020 15:24:17 +0200 [thread overview]
Message-ID: <20201016132417.5175-3-m.limbeck@proxmox.com> (raw)
In-Reply-To: <20201016132417.5175-1-m.limbeck@proxmox.com>
Requires the pve-conntrack-tool. On migration the conntrack information
from the source node is dumped and sent to the target node where it is
then inserted.
This helps with open connections during migration when the firewall is active.
