new-vm --replace removes the old machine with virsh undefine --storage vda, which stops with storage volume is not managed by libvirt when the disk image at that path has been deleted by hand. The domain is still defined, so a plain provision-vm refuses too, and the operator is stuck between two refusals until they virsh undefine the domain themselves and virsh pool-refresh default so libvirt forgets the stale volume.

A hand-deleted image is a normal thing to find after an operator cleaned up a disk by path, which is the first thing they try when the disk is the thing they want gone.

Proposal: when the volume --storage names no longer exists on disk, --replace undefines the domain without --storage and refreshes the pool, then proceeds; a volume that exists keeps the current path. Both branches keep the existing refusals for a data disk at vda.

Found during the public install walk while resetting the laptop between runs.

`new-vm --replace` removes the old machine with `virsh undefine --storage vda`, which stops with `storage volume is not managed by libvirt` when the disk image at that path has been deleted by hand. The domain is still defined, so a plain `provision-vm` refuses too, and the operator is stuck between two refusals until they `virsh undefine` the domain themselves and `virsh pool-refresh default` so libvirt forgets the stale volume.
