[PATCH-SERIES qemu-server 0/3] fix #7743: api: disk import: avoid locking twice when importing from OVA or same VM

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

When import_from_volid->() is called, the VM configuration of the
destination VM is already locked. In case the source volume belongs to
the same VM, there would be a second attempt to lock the config. In
particular, this also happens when importing from OVA, because the
source image is first extracted and belongs to the same VM.

Additionally, the update VM API call is changed to fork before
locking using the usual early+repeated checks pattern.
