Subject: [pve-devel] [PATCH v2 qemu-server 1/1] Do not start VM twice when rollbacking with --start
Date: Mon, 21 Nov 2022 14:13:03 +0100 [thread overview]
Message-ID: <20221121131303.268816-1-s.hanreich@proxmox.com> (raw)
When rollbacking to the snapshot of a VM that includes RAM, the VM
gets started by the rollback task anyway, so no additional start task is
needed. Previously, when running rollback with the --start parameter
and the VM snapshot includes RAM, a start task was created. That task
failed because the VM had already been started by the rollback task.
Additionally documented this behaviour in the description of the --start
parameter

Changes v1 -> v2:
Do not parse config for checking type of snapshot but rather directly check
whether VM is running or not via check_running()
