Any answers to this?

Hi,

I tried including public/sysctl.h for  XEN_SYSCTL_getdomaininfolist, but  I get an error: public/sysctl.h: No such file or directory.

Even if the above problem is solved, how will I get the list/domainIds of all the domUs running without using for_each_domain defined in xen/sched.h? I get the same error for this file as well. And what should be the parameters to make for this? Currently my Makefile is obj-m := mymodule.o and I'm running make with the parameters make -C /lib/modules/2.6.18-xen/build/ modules M=`pwd` V=1


This is the output from make:

Is your module for dom0?
If dom0, you can use hypercall of XEN_SYSCTL_getdomaininfolist.
But If other, you cannot access it.
