Subject: Fix regression for "-drive file="
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=dd5b0d71d660a4e31bdf8bd0d130ce582833db9f;p=qemu.git

Fix regression for "-drive file="

Empty file used to create an empty drive (no media).  Since commit
9dfd7c7a, it's an error: "qemu: could not open disk image : No such
file or directory".  Older versions of libvirt can choke on this.
