Subject: tests: qemuxml2argv: Allow testing of config processed at startup
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=f0a528ce06c54ade0df62b8c16ec0fec7bacf732;p=libvirt.git

tests: qemuxml2argv: Allow testing of config processed at startup

Add a new kind of XML output test for the files in qemuxml2argvtest
where we can validate setup and defaults applied when starting up the
VM.

This is achieved by formatting of the definition processed by the
qemuxml2argvtest into a XML and it's compared against files in
qemuxml2startupxmloutdata. This test is automatically executed if the
output file is present and it's skipped otherwise.

The first example test case is created from 'disk-drive-shared' test
case.
