Finally found this bug after 3 attempts to get virt-manager working. I eventually switched to CentOS but went back to Ubuntu when 12.04 was released to give it another shot. No problems under CentOS but still the same problem with Ubuntu. After a while finally managed to find this page using Google.
Any guess as to when this issue will be resolved? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/520386 Title: libvirt-bin hypervisor does not support virConnectNumOfInterfaces / unable to create domain with virt-manager using network bridge To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/520386/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
