Subject: tests: Add virresctrltest
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=ae885bb52089b1d367e7ac1ed5d8d683e0bfefbd;p=libvirt.git

tests: Add virresctrltest

This test initializes capabilities from vircaps2xmldata (since it exists there
already) and then requests list of free bitmaps (all unallocated space) from
virresctrl.c

Desirable outputs are saved in virresctrldata.
