This has just happened to me. For some reason, all my machines had machine='pc-i440fx-wily'. After an update in yakkety, they stopped working.
$ qemu-system-x86_64 -enable-kvm -machine help | grep wily So I updated the machine xml to a supported machine as Charles suggested, and they work again. Here's the note for my future self about how to do the update: $ virsh dumpxml $machine-name > /tmp/machine.xml Edit the xml. $ virsh define /tmp/machine.xml -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1305402 Title: libvirt fails to start VirtualMachines To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1305402/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
