  • Thread-topic: getting domU current privlege level?
Hello,
 
I am looking for a way to access the CPL of a running domU from a user program in dom0.  Is this possible?  I have looked at the vcpu_get_context structure, and noticed that a couple parts of the CS register can be accessed, but not the CPL.  Does anyone know if it is possible to access these lower 2 bits of the CS register?
 
Thanks,
Ryan
