[Qemu-devel] Saving and restoring CPU state

[eady]

I'm experimenting a bit with QEMU and am in need of a way to save and 
restore X86 CPU state including the pc so that the processor state can 
be rolled back to re execute from the previous point. I've found the 
functions "cpu_x86_fsave" and "cpu_restore_state" but do not understand 
them well enough to use them. Does anyone have tips on how to store the 
processor state in an auxiliary data structure and then restore it at a 
later point?

Thanks
