Hmm, indeed. This might have been broken by the transition to a systemd service: In newer versions that is: $ service qemu-kvm status ● qemu-kvm.service - QEMU KVM preparation - module, ksm, hugepages Loaded: loaded (/lib/systemd/system/qemu-kvm.service; disabled; vendor preset: enabled) Active: inactive (dead)
From: $ dpkg -S /lib/systemd/system/qemu-kvm.service qemu-system-common: /lib/systemd/system/qemu-kvm.service And particularly interesting is the default: $ systemctl is-enabled qemu-kvm.service disabled While the older sysV script was handled by the compatibility generators, and became $ service qemu-kvm status ● qemu-kvm.service - LSB: QEMU KVM module loading script Loaded: loaded (/etc/init.d/qemu-kvm; bad; vendor preset: enabled) Active: active (exited) since Mi 2017-09-20 16:17:44 UTC; 2 weeks 6 days ago $ systemctl is-enabled qemu-kvm.service qemu-kvm.service is not a native service, redirecting to systemd-sysv-install Executing /lib/systemd/systemd-sysv-install is-enabled qemu-kvm enabled This seems to have been changes in zesty already (qemu 2.8) and thereby Ubuntu Cloud Archive Ocata as well (Which I assume you use given you see that issue on kernel 4.4). In that case I wonder why not more are seeing this issue - never the less it should be fixed. ** Changed in: qemu (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720397 Title: qemu-kvm doesnt restart after node reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1720397/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
