Comment (by lerdmann):

I had a trap on bootup: SMP kernel, one CPU only, no I/O APIC VM
emulation, no PSD loaded.
As I can tell from the trap screen, the CR0.NE bit is NOT set even though
it's an SMP kernel. Does that mean that I either need a PSD to operate or
that the OS needs its time to change from CR0.NE = 0 to CR0.NE = 1 ? How
do you handle Win 9x and DOS guests ? As far as I understand they also set
CR0.NE = 0.
