Hi,
I'd like to extend xentop, so after some study I realized that I have
to start extending libxenstat. Let's say I want to know how many
free_pages a domain has, so I added a field in xen_sysctl_physinfo
(include/xen/interface/sysctl.h) and one in xen_domctl_getdomaininfo
(include/xen/interface/domctl.h). CIIW, I think the flow is like:
libxenstat -> libxc -> xc_physinfo -> ? I think that here I've got to
check the kernel side interface in drivers/xen/privcmd/privcmd.c but I
can't find anything that takes care of handling some physinfo struct.
Am I completely off road here? Do I have to look into the hypervisor
instead of the guest kernel?
Thanks,
Carlo
