We need to use the 'effective' storage nodename (one which includes the

The 'virt-aa-helper' process gets a XML of the VM it needs to create a
profile for. For a disk type='volume' this XML contained only the
pool and volume name.
The 'virt-aa-helper' needs a local path though for anything it needs to
label. This means that we'd either need to invoke connection to the
storage driver and re-resolve the volume. Alternative which makes more
sense is to pass the proper data in the XML already passed to it via the
new XML formatter and parser flags.
This was indirectly reported upstream in
https://gitlab.com/libvirt/libvirt/-/issues/546

Re-translating the disk source pools when reconnecting to a VM makes no
sense as the volume might have changed or pool became inactive. The VM
still uses the original volume though. Failing to re-translate the pool
also causes the VM to be killed.

Re-translating a disk type='volume' definition from a storage pool is
not a good idea in cases when the volume might have changed or we might

Specific cases are if a storage pool is not activated on daemon restart,

to setup labelling for apparmor.

In my recent commit of v9.8.0-rc1~7 I've introduced validation
wrt other memory devices. And mostly works, except when doing
memory device update ('virsh update-memory-device') because then
@mem is just parsed <memory/> device XML and thus its pointer is
not in the vm->def->mem, yet. Thus my algorithm which skips over
the same entry fails. Fortunately, we require full device XML on
device update and thus we can use device address and aliases to
detect duplicity.
