[libvirt] storage lock issues

Hi all, I'm investigating a crash in the storage driver, and it seems the solution is not as obvious as I wanted it. Basically what happens is that libvirtd crashes due to the pool refresh thread clearing the list of pool volumes while someone is adding a new volume. Here is the valgrind log I have for that: http://paste.opensuse.org/58733866 I tried adding a call to virStoragePoolObjLock() in the virStorageVolPoolRefreshThread(), since the storageVolCreateXML() appears to have it, but I'm getting a dead lock. Here are the waiting threads I got from gdb: http://paste.opensuse.org/45961070 Any idea what would be a proper fix for that? My vision of the storage drivers locks is too limited it seems ;) -- Cedric
