Hi Neo,
I think you mean the python function do_secondary_bus_reset().
Could you please detail the issue you meet with?
If you want to not use that for debug's perpose temporarily, you can just 
modify tools/python/xen/util/pci.py: do_FLR(). (and you may also need to remove 
some checkings in tools/python/xen/xend/server/pciif.py:setupDevice()), then 
execute "xend restart" to make the changes take effect.

I think we need this feature at least for debugging purpose, right?

Or, do we already have this feature?

Thanks,
Neo

I would remember that if researchers were not ambitious
probably today we haven't the technology we are using!
