But they provide different grades of transitivity, which is where all
the confusion lays.

Hi!
Some days ago, I discovered the 'xentop' tool (somebody mentioned it here:
http://discussions.citrix.com/topic/374218-what-can-we-do-to-decrease-the-time-needed-for-snapshot-reverts/
)
We work with XenServer 6.5 and we use long names for our virtual
machines to distinguish between them.

In Xen 4.7 we are refactoring parts libxenctrl into a number of

One such library will be libxenevtchn which provides access to event

Until the previous patch this relied on xc_fd(), which was only
implemented for Xen 4.0 and earlier.
Given this wasn't working since Xen 4.0 I have marked this as disabled

Removing this support drops the use of a bunch of symbols from
libxenctrl, specifically:
- xc_domain_create
libxenctrl links against this library.
Also, request the compat xc_map_foreign API from libxc.

Much like for gnttab and foreignmemory xencall hypercall buffers need
care.
Evtchn is a bit simpler (no magic mappings) but may not work from
parent + child simultaneously, document "parent only" since it is
consistent with the others.

v2: Adjust for libs/$lib layou
Using an existing libxenctrl handle after a fork was never
particularly safe (especially if foreign mappings existed at the time
of the fork) and the xc fd has been unavailable for many releases.
Reopen the handle after fork and therefore do away with xc_fd().

Currently, all newly added memory blocks remain in 'offline' state unless
someone onlines them, some linux distributions carry special udev rules
like:
SUBSYSTEM=="memory", ACTION=="add", ATTR{state}=="offline", ATTR{state}="online"
to make this happen automatically. This is not a great solution
This step is consistently timing out when run on cubietruck-*. Judging
from the logs it appears to be completing during the 30s slack added
by tcmdex (i.e. after the timeout message the rest of the output
appears in the test step log).
