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

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) -- error compiling committee.c: too many arguments to function ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
