[qemumigrate.pm] Subject: [pve-devel] [PATCH qemu-server] copy conntrack information on migration X-BeenThere: pve-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox VE development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 16 Oct 2020 13:24:54 -0000 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.
