Review Comment:
   I had faced the following issue while backing up the VM:
   ```
   # virsh -c qemu:///system backup-begin --domain i-2-10-VM --backupxml 
/tmp/csbackup.HEGID/i-2-10-VM/2024.10.07.02.44.28/backup.xml
   error: operation failed: failed to format image: 'Could not write qcow2 
header: Permission denied'
   ```
   As per 
https://unix.stackexchange.com/questions/622194/how-to-use-qemu-kvm-virtual-machine-disk-image-on-smb-cifs-network-share-permis
 adding nobrl solved it - so I used that fix.
