I have installed several operatings systems under qumu. Host OS is ubunti 17.10, guest OSes are MS-DOS 6.22, OS/2 warp 4.52, Windows 98 SE. In all cases, keys on my keyboard are non-functional even though they work in the host. And I also tested the keyboard on real hardware running both Windows 98 SE and OS/2 Warp 4.52 and those keys do work. So, the OSes do support the keys yet qemu is somehow blocking them. The keys that do not function in qemu are:
arrow up arrow down arrow left arrow right insert home page up page down end delete
How do I get these keys functioning in the guest OS under qemu?
