unraid crashes when starting vm

[fonts]

ok so here goes

i had unraid working fine with a virtual machine and graphics and sound passed through to the guest but unfortunately i broke unraid and had to reinstall.

i got a brand new usb setup the array and let the parity run and everything was sweet.

i then spent the next couple of nights figuring out how to passthrough the SSD drive to the guest.

got that all running sweet with graphics card via vnc.

now every time i try and pass through the graphics to the guest my unraid locks up and i have to force restart the machine.

i originally had issues with the graphics not working and crashing when starting the vm and i had to run it with PCIE override set to YES, i then did some more reading and found if i move the graphics card to a different slot this will fix the issue ( by moving the graphics card to a different IOMMU group) and it did so i changed PICE override back to NO and it ran perfectly, so i dont understand why it keeps breaking now.

 

here is my config for the test guest i have just created.

Try passing through your graphics card audio device also. There have been a few reports about this causing trouble lately.

aaaaaaaaand you my friend are a legend,that seems to have done the trick.

any ideas why it would have worked fine before using the onboard sound card ?
