better performance(more cores) ∝ Monterey instability(panic more often)

[cam8528]

this are the log from the mac Monterey.

i want to dedicate more processor cores to virtual box so that my virtual machine performs better. except the problem i am having is that it seems the more cores i try to dedicate to virtualbox, the more frequently fatal panic errors occur.

here are the log that is confusing to me

what do u think?

sincerely, cam8528

[cam8528]

here is a second log data to compare the first set with. i have no idea what this contrast means for increasing the amount of cores virtual box can provide for mac Monterey which is running inside my windows 10 installation.

also i was wondering how i could provision nvidia gpu resources into virtual box machines. is there a reliable way to do this? so that my virtual machine (mac monterey) has access to some gpu resources for small machine learning tasks

panic error log 2 for comparison to the first post:
