No. As suspected, both threads are reading internal list of domains (actually hash table).

error : virHashForEach:597 : Hash operation not allowed during iteration
Hey! On many of our servers, we often have the following error: error : virHashForEach:597 : Hash operation not allowed during iteration When querying the list of domains, this means libvirt will silently return 0 domain (most uses of virHashForEach don't handle the return code). We are using a hook, but the hook doesn't query libvirt back, so it should be safe from this point of view.
