Re: [Xen-devel] How to recognize which guest issues the hypercall?

[Big Strong <fangtuo90@xxxxxxxxx>]

Thanks for your replying and sorry for the behavior. Can I get that using libxc? Because I can't access the structure directly from dom0.

Why are you cross-posting this to both xen-users and xen-devel? This
is obviously a development question.

At any given time, "current" will point to the vcpu struct of the
currently-running vcpu; current->domain will point to the domain
struct. That should get you started.
