[libvirt] [PATCH] qemu: Don't try to find compression program for "raw" memory images

[Peter Krempa]

There's nothing to compress if the requested snapshot memory format is
set to 'raw' explicitly. After commit 9e14689ea libvirt would try to
run /sbin/raw to process them emory stream if the qemu.conf option
snapshot_image_format is set.
