Torkoal (our Jenkins node) was idle atm and Ryan reported he had seen the issues there before, so trying there as well. This is LTS + HWE - Kernel 4.10.0-38-generic, qemu: 1:2.5+dfsg-5ubuntu10
I thought about your case since you seem just to start a lot of them and reboot, this shouldn't be so much different to: $ uvt-simplestreams-libvirt --verbose sync --source http://cloud-images.ubuntu.com/daily arch=amd64 label=daily release=artful $ for i in {1..30}; do uvt-kvm create --log-console-output --password=ubuntu artful-${i}-bug1730717 release=artful arch=amd64 label=daily; done $ for i in {1..30}; do uvt-kvm wait --insecure artful-${i}-bug1730717; done $ for i in {1..30}; do uvt-kvm ssh --insecure artful-${i}-bug1730717 "sudo reboot"; done $ sudo grep "soft lockup" /var/log/libvirt/qemu/artful-*-bug1730717.log But this works for me :-/ Waiting for your feedback if you can trigger the same issue on a non- busy openstack system (could after all be some openstack magic at work that makes it behave differently). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730717 Title: Some VMs fail to reboot with "watchdog: BUG: soft lockup - CPU#0 stuck for 22s!
