Guest refuses to accept keyboard input when accelerated with WHPX
"Include the QEMU release version or the git commit hash into the description, so that it is later still clear in which version you have found the bug. Reports against the latest release or even the latest development tree are usually acted upon faster."
Git master revision 972e848b, compiled with MSYS2 and whpx headers from the Windows 10 SDK version 10.1.19041.685
"Include the full command line used to launch the QEMU guest."
qemu-system-i386.exe -accel whpx -hda HDs/WindowsUpgrade.vhd
"Reproduce the problem directly with a QEMU command-line. Avoid frontends and management stacks, to ensure that the bug is in QEMU itself and not in a frontend."
Causes the command prompt to return: whpx: injection failed, MSI (0, 0) delivery: 0, dest_mode: 0, trigger mode: 0, vector: 0, lost (c0350005)
then the guest refuses to accept any input but the cursor still blinks. Works fine with the tcg accelerator.
"Include information about the host and guest (operating system, version, 32/64-bit)."
Host: Windows 10 Enterprise Build 19042.985 64-bit with AMD Ryzen 5 3600
Guest: FreeDOS 1.3RC4 32-bit
