[pve-devel] [PATCH qemu-server] start: make not being able to set polling interval for ballooning non-critical

[Fiona Ebner <f.ebner@proxmox.com>]

The guest will be running, so it's misleading to fail the start task
here. Also ensures that we clean up the hibernation state upon resume
even if there is an error here, which did not happen previously[0].
