I have a Windows 10 and Ubuntu 19.04 VM that are suddenly failing to start with the message below.

I have started these VMs dozens of times without any issue. I didn't make any changes to the configurations or anything--most of the time I am working with the half a dozen containers that I have running, and those start just fine.

Does anyone have any idea what could be goin on with my VMs?

Code:

did you upgrade but did not reboot? on some amd cpus you need to load the new kernel for some cpu flags

can you post the output of 'pveversion -v' ?
 
It looks like that's what it was! I did an upgrade and then rebooted, and both machines started. Thank you!
