Comment # 3 on bug 1048783 from Richard Weinberger

Meh, fixed upstream a long time ago, please backport.

commit 69722fd7ac854f95eac65a4bf3fd86e65fbc470f

    tools: Ignore newlines in libvirt-guests.sh guest list

    The list file expects all guest UUIDs on the same line as the URI
    which the guests run on. This does not happen when the list is
    echo'ed in quotes. When stripping the quotes, newlines get transformed
    into spaces. Without this, only the first guest on the list is actually
    handled.

    Based on a fix by Omar Siam <simar@gmx.net>
