[Xen-devel] Can guest OS handle system calls by itself?

[Yan L. <yan...@ho...>]

hi there,

I'm wondering if the guest OS can handle most of the system calls by itself?
Only for these hypercalls defined in hypervisor.h, guest OS needs to go down
to Xen. For all other system calls, xeno handles in its own doamin well.

Is this understanding right? If not, how are the system calls handled?

Thanks,
Yan
