Hi!
First of all
So i run Proxmox 5.0-30 on this rig, the hypervisor use the igpu, and the 2 VMs use 1-1 of the GPUs.
Everyting works flawlessly, but i have decided to upgrade to Proxmox 5.2-1, i don't like updates so i did a clean install on another SSD set, and set everything the same as my old setup.
Which means:
1. I installed Proxmox on an ssd
2. Created 2 seperate lvm-thin storage on 2 seperate SSDs (1 for each VM)
3. Followed the PCI Passthrough wiki
4. Installed Windows 10 with the virtio drivers
5. Installed the latest GPU driver, which runs on the old system, without any problem
6. Applied MSISupported regedit fix on both VMs to get rid of the sound stuttering.
After all these i have a strange problem which i didn't encountered on the old system. If i run the 2 VMs at the same time, it produce heavy stuttering on both VMs (graphics, sound, mouse movement) and if i try some heavy workload it complelty freezes them. If i run only one VM at a time, everything works flawlessly.
Have you got any idea what cause this issue on 5.2-1?
Cause i'm out of ideas i tried this install procedure on the new set of SSDs on 5.0-30 again to check i didn't missed anything, and it works flawlessly!
