Avi:
	It seems we are using global TSS, and init_rmode_tss will modify
the table each time when VCPU is reset. Should we move to per CPU TSS
for correct real mode emulation?
thx,eddie

Why is it a problem?

But, the real-mode tss can definitely be improved.  Right now it uses 
guest memory, and it really shouldn't.  The best solution is probably to 
allocate a global tss (for all guests) out of host memory, and modify 
the mmu to map it at some safe location (like 4GB - 512KB - 12KB)
