When libvirt is gathering stats for block devices in the bulk stats API it would use the fallback code that accesses the files directly in libvirt both if the VM was offline and if qemu didn't return the stats at all.
It took me a while to understand what you wanted to say here. It would be nice if you could reword it :-)
If qemu is not cooperating due to being stuck on an inaccessible NFS share we would then attempt to read the files and get stuck too with the VM object locked. All other APIs would get eventually get stuck

waiting on the VM lock.
Avoid this problem by skipping the block stats if the VM is online but the monitor did not provide any stats.
