KVM hosts (both Ubuntu 22 and OL8 as OS) with NFS v4 primary storage
Using library: libvirt 8.0.0
Using API: QEMU 8.0.0

##### SUMMARY

Some volumes (only ROOT volumes) remains in Destroy state after the related VM is correctly expunged. Trying to manually delete them results in the following error: "cannot unlock file 'path-to-the-qcow2': Permission denied. Libvirtd run as root on the hosts and I found no permission/ownership issues on the qcow2 disks.

##### STEPS TO REPRODUCE

~~~
I'm not really sure on how to reproduce the issue, seems related only to root disks in our environnement, as data disks give no issues if I try to delete them.

##### EXPECTED RESULTS

When the VM is expunged also the root disk is deleted as well

##### ACTUAL RESULTS

~~~
The root disk remain in the UI in "Destroy" state

L’issue non indica alcun file sorgente, test o punto di ingresso. Inizia tracciando la pulizia dei volumi core durante l’eliminazione delle VM nell’ambiente KVM/NFS segnalato e indaga sul motivo per cui i volumi root rimangono nello stato Destroy; il lavoro è completato quando il volume root viene rimosso insieme alla VM eliminata senza l’errore di autorizzazione segnalato.
