Sorry for my late reply, but I had already completely wiped KVM and my bridge.
Redid the setup and the situation is like this. - With the default virbr0 everything works - Adding virbr1 on 192.168.120.0 routed has no effect on existing hosts, even when they get switched - Adding a 12.04 server with virbr1 as interface triggers the hang and high load - Adding 11.10 server with virbr1 works fine - Adding 12.04 with virbr0 and switching to virbr1 afterwards works too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/943918 Title: KVM hangs on creating domains, Qemu and virt-manager disconnect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/943918/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
