[pve-devel] [PATCH container 2/6] clone_vm: use destroy_config instead of manual unlink

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

and wrap the calls in an eval to preserve original errors causing us to
remove the config in the first place..

also, remove disks before removing the locked config (reverse order of
creation).
