so i have a ubuntu vm that keeps crashing and everytime i get this error

likely on CPU 11 (core 3, socket 0)

whats causing it? tried google didnt help i ran memtest no issues bios is up to date.. etc

ive tried to not enable cpu 11 or all of them just run off 1 cpu core.. but they always come back to cpu 11

i also get NVRM GPU errors at times too

fills the who log

but i rebooted comp so i cant do diagnostic of that.. but does the logs say whats causing problems

i also get this error

CIFS: VFS: reconnect tcon failed rc = -2 whatever that is

i added 2nd diagnostic

still cant figure whats wrong

if i load vms they will last a while then crash then get this cpu 11 core 3

here is a new diagnostic i also tried googling more and something about drivers but i running latest nvidia drivers then i downgraded nvidia drivers... i not sure how to test

is the cpu 11 core 3 on the cpu or the video card i wish sometimes the diagnostics could be more detailed narrowed down what was wrong... so i not sure what i should try to do or tests as memtest shows no issues with memory at least

so would the first diagnostics i have be video card or cpu or what not i wish i knew what some of these errors really ment google doesnt always have the answers

Moved to the correct subforum so more likely to be seen by users who can help.

oh i didnt know i was posting in the wrong area.. thought i always had to post under general.. unless its a feature request or one of the apps for community apps

new log file this is where the vm crashes gonna try to remove video card to see if its video card as i dont know i just trial and erroring now

update i pulled out the video card yet i still get the qemmu so the vfs and the qemmu happen is this a failing cpu?
