[Bug 1744169] Re: KVM + Virtio kernel panic
Hi Joseph. It's possible, but not ideal in my situation. I'm running Ubuntu 16.04 server VMs in KVM (via OpenStack) on a CentOS hypervisor, and I'm unable to easily reproduce the issue as it can occur on any of the 50+ VMs I have running. I'd prefer not to change the kernel on every VM if I can avoid it. Is there anything else I can do? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1744169 Title: KVM + Virtio kernel panic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1744169/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the proposed kernel and post back if it resolves this bug? See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Bug 1744169] Re: KVM + Virtio kernel panic
apport information ** Tags added: apport-collected ec2-images ** Description changed: I received the following kernel panic on a KVM VM which is acting as an OpenStack compute node. I'm unable to consistently reproduce this, but I do consistently get various kernel panics (this is only one of them). Is anyone able to shed any light on what might be happening here?
