And this particular code path here has some subtle misbehavior because we can remove a storage pool while we are in the middle of iterating over the list of pools... I'm going to hold off on pushing this, but I'm going to work on a series of other cleanups in this area that will include your patch Thanks, Cole -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
