My system is an Asrock x570 Taichi with a 3900x, 2 watercooled 1080TI’s and a 10gb PCIE NIC.
I run Manjaro otherwise exclusively but I’ve gotten into fixing up old videos so now I’m running Windows 10 through KVM. 12 pinned CPUs 16GB RAM and 1 of the 1080TI’s is being passed through with VFIO.
Now if I run a GPU heavy task in the Windows VM alone, it’s OK. If I run a GPU heavy task in the Linux host it’s OK. If I try to hit both the Linux and VM GPU at the same time with something heavy, the 10gb NIC disconnects immediately, I think Linux still sees it but I won’t get connected to anything until I reboot. Other than the heat the GPUs are fine when the NIC goes offline.
Trying to figure out what the issue is. Thinking maybe the GPUs are sucking too much power out of the PCIE slots and robbing the NIC but how can I test that or what else may be the issue?
