Subject: tests: validate an XML config with USB vendor/product set
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f61b083f3ddd0f2a934d3871086e1c9b080e4995;p=thirdparty%2Flibvirt.git

tests: validate an XML config with USB vendor/product set

The USB vendor/product is usually translated into a device/bus at
startup using the hostdev logic. We don't run the latter in the
unit test suite, but we can fake it by hardcoding a translation.
This demonstrates that we format the command line with the normal
device/bus properties, even when vendor/product is set.
