Public bug reported:
My virt-manager build VM Windows 10 guest had some problems when I
started using it in November 2023. I solved it along the lines of trying
to get the intel GPU working as a vGPU for this virtual machine. I
noticed some upgrades to the use of Nvidia were on the way. (It runs on
a laptop with Nvidia dedicated GPU).
Two kernel updates arrived in a row the past two weeks. I saw many gpu
features were involved though i'm not deep enough into Linux kernels to
know exactly what is going on.
The first one was the update to linux-image-5.15.0-92-lowlatency (and
it's accompanying modules and headers). The second one was linux-
headers-5.15.0-94-lowlatency. That one causes my VM to be slow as it was
at the start.
I use the intel gpu through a virtio driver since I cannot passthrough
the Nvidia card. I need that for several other applications. But with
the nvme Windows is installed on it works quite flawlessly for a while
now. Until this kernel update. I had to roll it back.
Thought it would be best to leave a note here.
