[Qemu-devel] [PATCH v2 0/3] qtest: add migration testing

[Jason Baron <jbaron@redhat.com>]

Hi,

Add a basic qtest for migration testing. Currently, it just tests a migrate of
machine 'pc' on the same host. Would be nice to extend to multiple machine
versions, but that requires multiple binaries, which could be done, but is
perhaps a bit awkward from qtest? Testing different machine versions within
the same binary doesn't seem like a real world test case to me. Currently,
the test aborts, if the migrate takes more than 2 minutes.

In any case, the test currently fails for q35, since ahci migration suport
isn't in place. Thus, I intend to add q35 testing here, once those ahci
migration patches are accepted.

Thanks,

-Jason

v2:
 * move core migration functions to libqtest.c
 * simplify Makefile dependencies
 * use 'mkdtemp()' instead of child pid to identify qemu instances
