Comment 38 for bug 362691

Due to some strange dependency interactions that nobody I've talked to has been able to explain, the prerm for python-xen-3.3 removes the pycentral-managed Python modules before the prerm for xen-utils-3.3 stops xend, which means that stopping xend fails.

The SRU for Jaunty needs to be updated to the attached patch, which holds off on restarting xend until after the upgrade. While this won't show up on the upgrade from 3.3.0-1ubuntu9 to 3.3.0-1ubuntu9.2, it would mean that any subsequent upgrades would break.
