I’m having problems with my Windows 10 Guest on a vfio GPU passthrough.
The systems sometimes can’t seem to get past the windows bootloader (not sure if that’s exactly where it stalls). When the VM stalls, I only get to see the Windows logo bootscreen and I never get to see the spinning dots under it.
After a couple of bad boots, the VM sees and tries to get into the diagnostic repair and we have the same situation. Either it stalls or we see the spinning dots and everything is fine (I can just do the normal startup from there to go to my desktop).
Also, when it stalls, I can see it hogs my first cpu core at 100% and doesn’t touch the other cores.
Otherwise, the guest runs perfectly, no other problems seem to arise once we’re past the boot.
Has anybody seen this kind of behaviour before?
I checked the dmesg logs and see nothing out of the ordinary when it stalls. Is there any way to have an easier time seeing what could be at fault here?
