i had the same problem with icehouse on ubuntu 14.04 LTS and fixed it with the following change in /usr/lib/python2.7/dist-packages/nova/virt/libvirt/driver.py
at line 4338 ff i removed for f in info['features']: cpu.add_feature(vconfig.LibvirtConfigCPUFeature(f)) and replaced it with test = [] for f in info['features']: if f not in test: test.append(f) cpu.add_feature(vconfig.LibvirtConfigCPUFeature(f)) maybe this helps someone until the fix is released. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1322681 Title: live-migration --block-migrate <UUID> fails: XML error: CPU feature `pdpe1gb' specified more than once To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1322681/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
