That works in dire emergency, but has the disadvantage of rendering the guest
unbootable in the process --- if you change the guest vgname, the initrd won't
be able to find the root filesystem.

That would be ideal, but I think it came up before and was rejected by the
installer folks. It's also too late for existing installs, of course; and we
still need to be able to support installs of old OS versions that don't do this.
