Tested new security patches on 8.2.

Network performance seems just fine. Have 4 Windows server 2019 and 2 Fedora Server VMs recording video feed. Haven't observed any difference in performance.

Supermicro SYS-1029U-TR4 with 768gig ram.
Network usage: about 400mbps constant.

I have a fully updated xcp 8.2 running with 2 nvidia quadro rtx 6000s.

GPU passthrough works as expected.
GPU PCI passthrough works as expected.
USB PCI passthrough of an ASMedia controller works as expected

However I cannot combine GPU and USB pci passthrough. Starting the vm just hangs. I see no errors, nothing of note in xl dmesg.

I have done this before with KVM on Fedora linux, on the same machine. So I know its not the hardware or bios.

Is there some underlying reason why USB and GPU PCI Passthrough together will not work?

Awesome Thanks Olivier.

Darn, I thought that might be the case. I have heard it does work with with ESX and Proxmox. I think Proxmox is KVM based, but not 100% sure.

I do hope Xen gets this figured out. This likely isnt a big deal for linux guests, but newer Windows guests (and their related security features) are starting to require this for their advanced security configurations.

I've seen a couple threads referring to nested hyper-v not working with XCP-ng. We're trying to implement Windows VBS (virtualization based security) in our 2019 servers. This apparently uses Hyper-V to achieve this. I've tested some of the settings used in the other threads in effort to get hyper-v to work, but have been unsuccessful at this point.

Just thought I'd check, has anyone had success getting it to run yet?

Thanks
