Windows 10 VM on unraid not starting up

Hi everyone,

I have a VM on my unraid with Windows 10 installed on it.

It's very unstable though, I very rarely manage to start it, mainly only after an unraid update.

Here are my logs:

Any idea why would it be so ?

 

Thank you,

Million reasons.  BIOS not up to date, bad memory, hardware not perfectly compatible with passthrough etc etc

 

But, what do you mean by "very rarely manage to start it".  Does it start and exit?  Do you get an error starting it?  Not that I'm the VM guy here, but more detail will be needed.

Hi, bios has been updated, when I start the vm there is no video output. Even with vnc I got nothing showing up. I just tried with another vm created from scratch and got the sa,e result. This one being a Linux vm. So indeed maybe my hardware is not perfectly compatible.
