Hi,

I face a strange issue on a Proxmox cluster server. It happened 4 times on Ubuntu 16.04 up-to-date guests on different nodes.
When I reboot the VM (sudo reboot), the VM seems to be stuck with CPU more than 100% (~105%).
I am not able to connect to SSH on the VM, i can't either have the virtual console thought web interface.
I got timeout when I try to stop/pause the VM, reset seems to not always work.
After I successfully shutdown/boot the VM, I don't find any information if the shutdown was improperly done.

Anyone have an idea why ?

I sometimes see this behavior when I have update the Proxmox packages but not rebooted the Proxmox server.

Having the same problem, just chiming in here and waiting for a fix or solution. Sometimes my Ubuntu LTS VMs just get stuck on reboot with 100% load and nothing but a power down helps. No reset possible.
