I have a strange issue with running an 'appliance' image based on FreeBSD 12 in bhyve on a machine with Ryzen 5800x processor. The problem is that the guest would run for a while and then the host would suddenly reset itself. It appears like a triple fault or something with similar consequences. The time may be from a few dozens of minutes to many hours. Just to be clear, no such thing occurs if I do not run the guest. Also, I have an older AMD system (pre-Zen), the problem does not happen there. A vanilla FreeBSD 12.3 installation that just sits idle also does not cause the problem. Does anyone have an idea what the problem could be? What workaround or diagnostics to try? Anybody else seen something like this? Since it's the host that resets it would be hard to capture any traces. Thank you. -- Andriy Gapon https://standforukraine.com https://razomforukraine.org
