Hi, Cláudio: Thank you for your summary, if we want to mask or unmask an interrupt, we can just add a hypercall in hypercall system corresponding to the function, ( This is based on the premise that the interrupt structure has been adapt to support this function.) However, could you direct me about how to track pending interrupt in a normal OS(then I can consider how to deal with this part in paravirtualization)? I'm not clear about this point.
Thank you very much. -- Best Regards. Youren Shen.
