OSes that barely work

Windows Vista, 7, 8.1, 10 - Will work if you load a 32-bit slim ISO. 8.1/10 barely runs since it only has 512 MB of RAM. If you're trying Win10, use earlier builds, otherwise it won't respond.
SerenityOS - WindowServer fails to start
QNX 6 - Runs fine but non-functioning mouse despite USB stack and USB mouse module for all HCIs running.

OSes that do not work on VM8

Doesn't work properly

Windows NT 3.1, 3.5, 3.51, 4.0 - BSODs on setup; Most likely due to early NT Kernel, You can install it manually using DOS. Another method is by using QEMU to install it directly to the hard drive.
JX, Ghost Kernel - Requires a PS/2 Mouse or you can't utilize the OS not even with keyboard shortcuts.

Doesn't work at all

NewOS, ArcaOS - Locks up at booting due to KVM
OpenSolaris, UnixWare, OpenServer - Bootloops
Windows 11 - Will not boot at all unless Microsoft releases a 32-bit version.
Tiny10 - Boots but gets stuck.
Windows Vista betas (Longhorn, post-reset) - Massive graphics issues (VM7), would likely not work at all.

Untested OSes

Windows 8
Windows Vista betas (Longhorn, pre-reset)
Windows Whistler
Windows 2.x - Tip: qemutab.img has a usb-tablet driver for 2.x, use it for working mouse.
