Multi-CPU issues when Hyper-V enabled

Post by Belisarivs »

I'm using Vagrant on a Windows 11 box to do a build of a decent sized Java webapp. The guest OS is a CentOS box. During the build process for the webapp, at seemingly random times, the VM would crash and I'd get a guru meditation error. Sometimes an error would show up in the logs, some times it wouldn't.

I also use WSL2, so one of the first things I did was turn off Hyper-V. Everything worked. But I really wanted to have WSL2 available as well, so I turned it back on and started playing around. I tried migrating over to VMWare Workstation, but I got the exact same sort of errors. Eventually, I tried reducing the number of CPUs down to 1, and that seemed to work - I'm not getting the random VM lockups anymore. While that works for my current situation, I thought I'd report the experience for others that might be encountering issues.

I've attached a log file that managed to capture the error. I've changed my username in the log to "belisarius" and the name of the VM to the prefix "foo".
