I've been experiencing something that sounds very similar to what has been described in this issue post and want to see if you guys think it's the same issue. For me from a cold boot everything is fine for a while and I can restart my vm and such just fine. but after a long time or stressful stuff

I haven't remembered to reset those interrupts in a year, but I also haven't remembered to update my drivers in about as long, so I could be still on the right setting. I've also been on AMD for that year, and I don't remember whether this bug applies to modern AMD cards. -- You received this

Updating NVIDIA drivers in the guest also seems to disable MSI for some reason. Oddly enough I did not run into the host hard locking though. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1580459

Oh, that is interesting. Using lscpi -v on my computer reveals that Linux tends to default to enabling MSI on my PCIe devices that support it (since the common opinion is that it's better for PCIe), including all my graphics cards, so the fact that vfio-pci and Windows 10 both default to disabling
