Dual gpu passthru for vms issues

[magicman32]

Hi All

What I am trying to do is have 2 gpus for passthru to 2 seperate vms

 

Problem: Installed 2nd gpu in unraid server (identical amd rx570 8gb cards)

when I start a single vm....my vms tab disappears and go to settings vm manger and thats gone too

 

Setup: I have a linux vm and a windows 11 vm installed

when it comes to vm setup each vm has its own gpu with seperate id (so I know which card is
which), each card has its own iommu group

 

Outcome: My server becomes so unstable to the point I have to reboot, because it freezes so I cant get any logs to see whats wrong........

at first I thought it was a power issue, I started with a 750w psu running 2950x threadripper 6 hdds and 2 amd rx570 8g gpus

 

So I upgraded the psu to a 1000w psu and getting same issues, So I have taken out 2nd gpu and system is now stable once more......

Im not sure if its a setup thing or that I have identical gpus

 

If someone has some insight to dual gpu setup that would be great, Im not sure what to check for in logs.........any help would be greatful, a bit lost and disappointed I cant get this working

 

I have same results with 6.9.2 and now with 6.10 rc1
