On F16 at least, empty volume groups don't have a directory under /dev. The directory only appears once a logical volume is created.
This tickles some behavior in BackendStablePath which ends with libvirt sleeping for 5 seconds while waiting for the directory to appear. This causes all sorts of problems for the virStorageVolLookupByPath API which virtinst uses, even if trying to resolve a path that is independent of the logical pool.
In reality we don't even need to do that checking since logical pools always have a stable target path. Short circuit the polling in that case.

ACK. Isn't it funny how small a patch can be in proportion to the time it took you to analyze why that one if statement is needed? -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
