I had the same issue after upgrading nova components. The issue was that nova-conductor and nova-compute services did not use the same version.
I upgraded using apt-get upgrade but it didn't seem to update nova- conductor. After a apt-get -f upgrade nova-conductor the nova-conductor package was upgraded to same version as nova-compute and then it worked. Confirm by checking the package versions (dpkg -l | grep nova). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1490361 Title: IncompatibleObjectVersion: Version 1.2 of PciDeviceList is not supported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1490361/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
