[libvirt] [PATCH] xenconfig: xm: Fix checking for extra in parser
Parser assumed extra was always present when root was specified.

Although at first glance the logic seems a bit clumsy, my alternative attempts were no better. Also, similar logic exits in the xl config parser - see xenParseCmdline in xen_xl.c. ACK to the change, but we'll need a 'Signed-off-by:' to push. Regards, Jim

I'm guessing you came to this issue via https://bugzilla.redhat.com/show_bug.cgi?id=1327578 . In the future please add a link to the bug report in the git commit message Also this is a good candidate for extending the test suite, tests/xmconfigdata and tests/xmconfigtest.c Thanks, Cole
