Just a note [possibly more of a warning] that I'm intending to

Barring any bugs, the change ought to be transparent. The reasons why
we're making this change in Fedora are:
- Because in RHEL 7 this will be the default and we want to test it.
- Improved encapsulation and security through sVirt.
- Allows us to implement advanced features, especially disk
hotplugging and access to remote disks.
Note there's no change upstream. libvirt still isn't required.
It took a while, but this should happen today.
In Rawhide: libguestfs >= 1.19.36-1.fc19
In F18: libguestfs >= 1.19.36-1.fc18
To tell if your version of libguestfs uses libvirt do:
$ guestfish get-attach-method
(If it prints 'appliance' instead of 'libvirt', then it's using the
non-libvirt direct launch method).
There ought to be no user-visible change. If you want you can switch
back to using the direct launch method by doing:
If you want to change the libvirt URI used, do something like:
(It sounds tempting, but this won't let you use Xen etc, although it
is now plausible that someone could patch libguestfs to make that work.)
