Не может открыть виртуальную машину после обновления до 16,10

Я только что обновил до 16,10 (от 16,04), и мои kvm виртуальные машины не могут запуститься больше. Я получаю эту ошибку:

Error starting domain: internal error: process exited while connecting to monitor: 2016-10-27T14:47:58.353049Z qemu-system-x86_64: -enable-kvm: unsupported machine type
