Intel iGPU passthough

@xerxist have you tried with the 8.3 beta of XCP-ng? I believe it's got a newer kernel maybe?

xerxist

Yes I'm running 8.3 Beta

Is this just the mediated (gvt-g?) device passthrough, so the XCP side/server maintains video but a VM can make use of the resources as well?

I am very interested in this (plex, frigate type use) as a stepping stone away from Proxmox.

Thanks

In my testing of this, iGPU passthru works fine in Linux but in Windows the device will show an error in the device manager, disable/enabling the drive in the device manager will allow it to work, until next reboot.

@bullerwins @xerxist @flakpyro

What are you using for display output on the host since you're passing the iGPU to the VM?

flakpyro

@CJ Im running server grade hardware that has remote lights out management with iKVM support. Otherwise yeah you would lose access to the display output.

xerxist

@CJ

No output just need the Intel quick sync.

CJ

@xerxist Yes, QS for the VM but there are times when having a local display of the console comes in handy. That's why I haven't done mine.

@bullerwins said in Intel iGPU passthough:

@olivierlambert I tried but getting this error when turning on the VM

INTERNAL_ERROR(xenopsd internal error: (Failure
"Error from xenguesthelper: Populate on Demand and PCI Passthrough are mutually exclusive"))

Not sure what it means

EDIT: after googleing it seems that static and dynamic memory has to be the same:

@bullerwins thanks for this. I had to restore a VM from a backup and while it was down changed the dynamic value. This certainly saved me some time. I was positive it had to do with remapping the UID on the VM or something on the host side of it. anyways, thanks.
