Subject: [PATCH] cputune: allow interleaved xml
https://bugzilla.redhat.com/show_bug.cgi?id=1101574
I noticed this with the recent iothread pinning code, but the
problem existed longer than that. The XML validation required
users to supply <cputune> children in a strict order, even though
there was no conceptual reason why they can't occur in any order.
docs/ changes best viewed with -w
* docs/schemas/domaincommon.rng (cputune): Add interleave.
* tests/qemuxml2argvdata/qemuxml2argv-cputune-iothreads.xml: Swap
up order, copying canonical form...
* tests/qemuxml2xmloutdata/qemuxml2xmlout-cputune-iothreads.xml:
...here.
* tests/qemuxml2xmltest.c (mymain): Mark the difference.
