[Qemu-devel] [PATCH for-3.2 00/10] vhost: preparation for qgraph conversion of vhost-user-test

[Paolo Bonzini]

The vhost-user-test is one of the most complex qtests in the tree,
and converting it to qgraph poses some unique challenges.  This series
addresses them in a way that does not depend on the qgraph conversion
itself, but prepares for it.

First of all, vhost-user-test is slow and that is a pain when debugging
it. :) So patches 1 and 2 fix this bug.

Second, qgraph will be able to test vhost-user-test on pSeries and ARM
virt (with virtio-mmio) machine types.  Patches 3 and 4 prepares for this
by compiling vhost-net even on TCG-only targets, and by supporting
wrong-endianness vnet headers.  Patches 5 and 6 instead make the test
more robust, so that it can run on those machines too.

Third, vhost-user-test is a bit strange in that it has more global state
than other tests (in particular a GMainLoop, but also a directory in /tmp
and some weird uses of global_qtest).  Patches 7 to 10 thus remove this
global state already, which simplifies the code and also will reduce
the diff for the qgraph conversion.

Please review and ack!  Thanks,

Paolo
