...ou to open files which have a "json:" QEMU pseudo-URL as backingfile, whereas previously it would fail hard in this case (RHBZ#1134878). When virt-v2v performs conversions from Xen (over SSH) or vCenter (over HTTPS) it uses these pseudo-URLs as backingfiles. We had to tell people to use LIBGUESTFS_BACKEND=direct to avoid libvirt in this situation. This commit narrows the check so it will now only print the error if libvirt < 2.1.0 and LIBGUESTFS_BACKEND=direct is not set. Also the error is modified to tell users they can either upgrade libvirt or set LIBGUESTFS_BACKEND=direct to work around the...

I didn't see what are the main differences in http://libguestfs.org/guestfs.3.html#backend Specifically, I'm interested in what is faster (direct sounds faster to me), and if there are any major restrictions (networking?) Here's an example command we are running (sorry, Python'ish, but you'll get it): ['virt-sysprep', '--connect', 'qemu:///system',
