Virtualbox 6.1 on Windows 11, Dell XPS13 9360, 16 GB RAM, 2 TB SSD, running Linux 22.04 Guest
Used to work fine until two weeks ago.
Installed WSL2 (with Wayland GUI support), installed Linux 22.04, OMNeT++ 6.0.1, etc in WSL2
Restarted Virtualbox yesterday and got "kernel panic not syncing attempted to kill the idle task" (clean start from powered off machine)
Decided to update to Virtualbox 7.0.6 to see if there is an interoperability issue between WSL2 (with WSLg) and Virtualbox 6.1
I also have another Dell XPS13 laptop running both WSL2 (with WSLg) and Virtualbox 7.0 successfully
Same result (also for all advanced startup options on startup screen): "kernel panic not syncing attempted to kill the idle task".
Also checked (in BIOS) that virtualization is enabled
Log file and screenshot attached.
Any suggestions/questions are welcome, thanks!

Re: virtualbox kernel panic not syncing attempted to kill the idle task
Enabling WSL2 enables Windows host OS Hyper-V, which causes some issues. HMR3Init: Attempting fall back to NEM (Hyper-V is active)
Try two processors in the VM.
Oooooh, yeah.... Long-term fight between the devs and Microsoft. They're getting ahead, though.viby wrote: see if there is an interoperability issue between WSL2 (with WSLg) and Virtualbox

Although I (think to) know what you mean, I'm not so sure who "They" are.scottgus1 wrote:Long-term fight between the devs and Microsoft. They're getting ahead, though.
Re: virtualbox kernel panic not syncing attempted to kill the idle task
Two CPUs in the VM worked. It seems that using one CPU (one thread in Intel terminology) may lead to security concerns, but two threads = one core (in Intel terminology) is allowed.
