Ive tried both windows 10 and linux vm's and after about a day of running they will both lock up and cause all cores to peg 100%. I will have to force stop and restart everytime so currently vm's are completely useless to me at the moment. Ive seen other posts about this same issue but their issue was something completely unrelated to what im using, something about their pci device or file system. im using the latest version of unraid. Please let me know what you need to help figure this out as I am fairly new to unraid.

You may have tried virtiofs if not usings

I have made the changes and am starting the vm, ill reply back tomorrow to see if the problem persists.

well so far it hasnt locked up yet

I've been plagued by Windows 11/VM Freezing up while the other 2-3 vms were fine, removing 
<memoryBacking>
    <nosharepages/>
    <source type='memfd'/>
    <access mode='shared'/>
  </memoryBacking>

 

Fixed my issue now too, the VM has been up for 2 days where as before within hours it would freeze, the CPU/Cores would be 100% in the dashboard and as soon as force shutdown would go back to normal and get me few more hours but so far soo good.

 

I guess In summary, not having this configuration doesn't significantly impact my VM's performance or functionality, and it eliminates potential compatibility issues or freezes. Unsure if that was due to virtios or enabling and disabling things later, I wish there is a tuner addon to check on that and remove unwanted, not needed features/xml formats.  Had to do some compare vms, xml and remove additional stuff but glad I found this post to fix my issue.
