There's got to be some difference between your staging environment and
your production environment, and I'm pretty sure it has nothing to do
with the version of oVirt.
Are you running virt-v2v inside a virtual machine, and previously you
ran it on bare-metal? Or did you disable nested KVM? That seems like
the most likely explanation for the difference (although I'm surprised
that the difference is so large).

[PATCH] daemon: build also without Hivex.OPEN_UNSAFE (RHBZ#1493048)
by Pino Toscano
Do a configure check for the OPEN_UNSAFE flag in the OCaml binding of
Hivex, using it only when available. This makes it possible to use
hivex < 1.3.14 to build libguestfs (the daemon, actually).
Amend the building documentation accordingly.

[nbdkit PATCH] file: Add trim support
by Eric Blake
We already have support in the file driver for punching holes
during .zero with the may_trim flag (via FALLOC_FL_PUNCH_HOLE),
so we should use the same mechanism to support .trim. Note that
the NBD spec says that trim is advisory (we can return success
even if we did nothing); but at the same time, it's nicer to
avoid advertising the feature if we know for sure we can't do
it, so we also need .can_trim. Note that there's still an
element of runtime behavior, as FALLOC_FL_PUNCH_HOLE doesn't
work on all filesystems; there we fall back on the NBD
protocol allowing us to be advisory for all but a handful of
errno values that we can directly report back over NBD.
Signed-off-by: Eric Blake <eblake(a)redhat.com>
---
I couldn't test --filter=log results on trim commands without
at least one plugin that supports trim ;)

[PATCH] customize: allow missing SELINUXTYPE in SELinux config
by Pino Toscano
libselinux defaults to "targeted" when no SELINUXTYPE is specified in
/etc/config/selinux. Hence do the same here, instead of failing because
of the missing key.
Add a slow test for checking SELinux relabeling on a Fedora 27 guest,
both with no changes, and with a modified configuration.

[nbdkit PATCH 0/2] RFC: tweak error handling, add log filter
by Eric Blake
Here's what I'm currently playing with; I'm not ready to commit
anything until I rebase my FUA work on top of this, as I only
want to break filter ABI once between releases.
Eric Blake (2):
backend: Rework internal/filter error return semantics
filters: Add log filter
