Initially it sounded a bit like some part of the graphics causes issues. But then this would hang or drop to a textual mode and not shut off the VM. If this is still happening, is the shut down immediate (like ripping out power) or slightly delayed (doing a shutdown sequence like if the power button was pressed on a real system)?
There might be further info on the host in /var/log/syslog, /var/log/libvirt/libvirtd.log, and in a qemu log named after the VM name under /var/log/libvirt/qemu/. If you can still reproduce, the shutdown still, please attach the above logs here. Thanks. ** Changed in: qemu (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1426893 Title: qemu-kvm virtual machines crash with some but not all ubuntu flavors when vmvga video is selected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1426893/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
