I have some Windows 10 guests that have issues with keyboard response. It's not all windows 10 guests on that same host that exhibit this behavior and, even more strangely, if I can start a Cygwin terminal on the problem guest, the terminal responds to the keyboard.
I suspect that the difference between guests may be due to Microsoft updates installed or blocked at the firewall. At one time ask these guests responded properly to keyboard input. I am using KVM/QEMU on Rocky 8. Has anyone else seen this? Any possible solutions?
