[PATCH 0/2] Support for LUKS-encrypted Linux guests
by Richard W.M. Jones
These two patches add minimal support for LUKS-encrypted Linux guests
(ie. most common whole-disk encryption schemes).
Only opening LVM-on-LUKS is supported by this, not, for example,
changing keys or creating new encrypted devices. It's also a little
clunky to use from guestfish, but we can add more commands to fix that
once we have a better handle on the problem.

[PATCH 0/2] Improve the performance of virt-df
by Richard W.M. Jones
Currently virt-df launches the appliance once for each guest. With
these two patches the number of times the appliance launches is
reduced to once every 26 block devices.
In theory we could do better by adding support for disk hot-add
(supported by qemu but not via libguestfs at the moment). However
this patch is still an improvement on the current situation.

[PATCH] Documentation: Cleanup virt-v2v.conf references and mention --network
by Matthew Booth
virt-v2v.conf is no longer required on the command line in most circumstances.
This change removes it from the command line in all examples.
This change also references an optional --network parameter in all examples, as
this typically will be required.
