[Xen-users] Intention to deprecate and remove some Python libxc bindings

[Juergen Gross <jgross@xxxxxxxx>]

Mostly for historical reasons Xen includes Python bindings for libxc.
They have been used by xm/xend in the past but nowadays there is only
one usage in the Xen source tree: pygrub is using xc.xeninfo().

I wrote a patch to remove all libxc Python bindings but xc.xeninfo() and
got some feedback regarding out-of-tree users. Up to now there have been
reports of users of the following bindings:

    xc.getcpuinfo()
    xc.domain_getinfo()
    xc.tmem_control()
    xc.domain_set_target_mem()
    xc.domain_setmaxmem()
    xc.physinfo()
    xc.xeninfo()

Before removing all but above bindings I'd like to ask for any other
users of the libxc Python bindings. In case you are using one of those
and are planning to do so with Xen 4.7 and later, please stand up and
tell me, in order to keep the specific binding.

Just for reference: There are no known users of:
