Solaris 10 U1	32	kvm-12	Intel	64	Works	later releases will detect the CPU is 64 bit capable and try to default to run a 64 bit kernel and fail, for those you have to override Solaris autodetection by adding "kernel/unix" to the kernel multiboot entry in GRUB
Solaris 10 U3	64	kvm-54 + patches	Intel	64	Works	needs additional patches to qemu (qemu-ide-*) and kvm (kvm-kernel-*) from [1] which are scheduled for future releases
Nexenta OpenSolaris beta 3 test 1	64	kvm-53	Intel	64	Could Work	needs additional patches to qemu (qemu-ide-*) from [2] but still crashes and kills itself; later versions had regressions and would crash as shown by bug 1841658

FreeDOS 1.0	32	kvm-12/14	Intel	64	Work(ish)	Can only be installed from live CD by disabling kvm and using qemu only. Upper memory management (himem.exe) crashed kvm. Some other drivers do so as well. Step through booting using F8 to determine which. DOS is confined to the lower 640K of memory. See bug 1666308.
