Subject: [PATCH] vmx: shortcut earlier few 'ignore' cases in virVMXParseDisk()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Move earlier the checks for skipping a hard disk when parsing a CD-DROM,
and for skipping a CD-ROM when parsing a hard disk. This should have no
behaviour changes, and avoids to add repeated checks in following
commits.
