I have Ubuntu 22.04 installed on a windows 10 machine using VirtualBox. Occassionally it will freeze (once while using it but mostly I find it frozen after walking away from the PC when I return.

Has anyone suggestions on where to look for logs or how to troubleshoot (or even better solve) this issue?

Update 1 error found after running journalctl:

kernel: [Firmware Bug]: TSC doesn't count with P0 frequency!
kernel: APIC calibration not consistent with PM-Timer: 108ms instead of 100ms

I experienced the same, what helped me was using only 2 cores instead of 16 and set the cpu execution cap at max 85%.

Especially the execution cap made everything stable.
