[libvirt] default storage pool will not start

Long ago I had a VM that used a qcow image that was in the default directory-based storage pool. Since then the VM and the image have been deleted. But now libvirt will not start without the image file: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/host.py", line 586, in start_pool pool.start() File "/usr/share/virt-manager/virtManager/storagepool.py", line 67, in start self.pool.create(0) File "/usr/lib64/python2.6/site-packages/libvirt.py", line 1039, in create if ret == -1: raise libvirtError ('virStoragePoolCreate() failed', pool=self) libvirtError: cannot open volume '/var/lib/libvirt/images/gstable.qcow2': No such file or directory If I simply "touch" the file, then the pool starts. But I don't want it around. No other vm's reference this file. I've tried deleting and re-creating the pool. I've tried removing all the files in the pool, removing the directory, mkdir'ing the directory and then re-creating the pool, but it still will not start without that file. I've grepped /etc/libvirt for the existence of that filename but it doesn't exist. For the life of me I can't figure out where libvirt is getting this information from and why it thinks it needs this file.
