[vbox-dev] Why are so many guest OSes (such as RedHat and Win98) are not working?

[Alexey Eremenko]

hi all !

Why are so many guest OSes are not working?
such as RedHat Linux 7/9/FC1 and Win98, Xandros 3 and Solaris 10 fails also.

working guest OSes:
SUSE Linux 10.0/10.2 and Win 2000/XP (with DOS somewhere in the middle
between working and non-working, it boots but has a lot of problems)

Why is this ?

That is - are most bugs in the BIOS or the CPU ring-0 emulation or where ?

Also why IBM OS/2 requires VT ?
Will Vanderpool make all those other guest OSes magically work ?

VirtualPC and VMware are capable of running a lot of OSes why?

... and I'm going to fill bug reports against VirtualBox, until I will
be able to run any x86 OS I have. (ok, I don't expect integration for
every OS in existence, but every x86 OS in existence should work (at
least in minimalistic mode, detecting mouse, keyboard, video, and hard
disk) - neither VirtualPC nor VMware achieved that, but there are much
closer to this ultimate target)
