I've been having bizarre performance issues when connecting to a VM hosted locally (machines have gigabit connection & ~5ms latency, so that shouldn't be an issue)
I used `virt-install` like so (using even deprecated `--accelerate`) `virt-install --name accelerated-test --ram 10240 --cdrom /home/tom/ubuntu-20.04.3-desktop-amd64.iso --os-variant ubuntu20.04 --virt-type kvm --accelerate --graphics vnc,listen=0.0.0.0`
after installing the vm, and connecting (via `vnc` or `spice`) the performance is bad, super high latency ~200ms, moving a window around the desktop causes lots of lag and many artefacts
After many debugging steps and reboot for some unrelated bios change; I started 2 vms, one felt near-native performance, the other terrible. After restarting them, it was terrible for both again.
The system is H11DSI-NT 2xEPYC-7601 + random 750ti I had lying around
