Failure during import

Hello, all. I have a Cobbler 2.003 install on CentOS 5.5 x86_64 in a VM (VirtualBox) that I am trying to get to import a distro. I have the CentOS 5.5 DVD mounted, and I issue this command: cobbler import --name=CentOS55 --path=/mnt The import goes fine until it hangs forever (or at least overnight) on the "createrepo" step. The cobblerd service also shut down at this point. The disto appears to be imported in the web ui, and I can select it and start the PXE booted install, but it shortly stops with the Kickstart error "Unknown Url method $tree". Any pointers for fixing whatever is broken here? Thanks! -Pete
