Virt-manager simply displayed the output. In fact I was finally able to sort out what went wrong. At some point back in an earlier installation, certain parts of the virtual environment were installed under /usr/local. That installation had not been removed with the upgrade. For some unknown reason, the python libraries in that got pulled when virt- manager was started and the version of those libraries were 0.600.0 (not the one actually installed on my system).
In my case, the solution was to remove the remains of the old installation. Afterwards, virt-manager started w/o problems, so your problem does not seem to be related to mine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1020883 Title: virt-manager does not start after 10.04 to 12.04 upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virt-manager/+bug/1020883/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
