[PATCH] daemon: selinux: Add setfiles -vv flags when verbose.
by Richard W.M. Jones
This shows which files are being relabelled. Also only use -q
(suppress non-error output) when we are not verbose.

Guestmount seems not to sync changes
by 张强
Hi all,
It seems guestmount always fails to flush changes to the mounted qcow2 snapshot.
To reproduce this problem:
1. take an external snapshot for a qcow2
2. guestmount the snapshot
3. do some changes, for example: `echo 123 > /test; cat /test`, right now /test can be seen created and containing the right content
4. fusermount -u {mount-point}
5. virt-cat changed file, for the example above, sometimes /test doesn't exist, sometimes /test does exist but has no content
My libguestfs version is 1.20.11, and it's running on CentOS 6.6.
I tried several ways to work this around, but none of them worked.
I suspect it's a cache problem, so I tried to wait a while before umounting the image, sometimes this way works, sometimes it doesn't.
I also looked into the documentation for syncing and caching options, I tried to mount the image with fuse options like:
guestmount -o direct_io -o sync -o sync_read -o big_writes -w
no luck either.
What could be the cause? Is mounting a snapshot a problem?
Thanks.

[PATCH] v2v: inspect source: Don't tell people twice to run virt-v2v -v -x (RHBZ#1167623).
by Richard W.M. Jones
There were two related bugs in the virt-v2v error messages when source
inspection failed.
Firstly it would print the message about running 'virt-v2v -v -x' twice:
virt-v2v: error: inspection could not detect the source guest (or physical
machine).
Assuming that you are running virt-v2v/virt-p2v on a source which is
supported (and not, for example, a blank disk), then this should not
happen. You should run 'virt-v2v -v -x ... >& log' and attach the complete
log to a new bug report (see http://libguestfs.org).
No root device found in this operating system image.
If reporting bugs, run virt-v2v with debugging enabled and include the
complete output:
virt-v2v -v -x [...]
And secondly it would tell you to run virt-v2v -v -x even if you were
running with verbose messages.
Further fix for https://bugzilla.redhat.com/show_bug.cgi?id=1167623
which updates commit ab7197476de1cb3c8727caf4da429f6293ca4227.
Thanks: Kun Wei.

[PATCH] inspect: get a better icon for ALT Linux guests (RHBZ#1433937)
by Pino Toscano
Use a 64px icon which is in the menu-icons-default package, hopefully
part of the default installation of any flavour.
Updates commit 9928296c1ca8df5bd8f108ed00039adc6468cac3.

[PATCH 0/4] p2v: fix virt-p2v-make-disk on Debian
by Pino Toscano
Hi,
this small series fixes the generation of Debian-based images using
virt-p2v-make-disk. With this series, the image can boot fine, X is
started, and the p2v interface appears. I haven't tried an actual
conversion, but I don't think there are Debian-specific problems
preventing that.
Thanks,
Pino Toscano (4):
p2v: fix Gtk dependencies on Debian
p2v: remove network-manager-applet Debian dependency
p2v: virt-p2v-make-disk: fix systemd paths
p2v: virt-p2v-make-disk: prevent daemons to run on Debian

[PATCH] python: check return value of Python APIs
by Matteo Cafasso
Addressing issue #1406906.
When constructing the returned objects, check the return value of
Python APIs.
This is especially relevant when dealing with non UTF-8 strings.
A RuntimeError will be raised on failure pointing to the problematic
entry and the field name.

[PATCH v2 0/6] v2v: Pass CPU vendor, model and topology from source to target.
by Richard W.M. Jones
v1 -> v2:
- Support for passing topology through -o glance.
- Support for passing topology through -o rhv.
- Use bool for acpi/apic/pae struct fields in virt-p2v.
- Write the xpath expression in error messages instead of file/line.
- Fix more memory leaks in virt-p2v cpuid.c.
- Passes make check & check-valgrind.
There may be some other minor changes. I believe that everything
mentioned in reviews has been fixed.
