[PATCH 1/3] generator: c: move internal functions
by Pino Toscano
Move the generate_all_structs and generate_all_headers functions,
previously internal within the implementation of generate_guestfs_h, to
be usable by other functions in the same "C" module (but not public).
Only code motion.

[PATCH 1/2] libvirt: un-duplicate XPath code
by Pino Toscano
Move the checks for empty xmlXPathObjectPtr, and for extracting the
result string out of it, to a new helper functions.
This is just code motion, there should be no behaviour changes.

[PATCH 1/2] kernel: refactor build_kernel & find_kernel
by Pino Toscano
Move the handling of the SUPERMIN_* envvars, and the kernel copy/symlink
out of find_kernel to build_kernel: this way find_kernel does only the
search. Also, the modules path search is done in by find_kernel as
well.
This is mostly code motion, with no behaviour changes.

[PATCH 0/5] Improve inspection of /usr filesystems
by Pino Toscano
Hi,
this patch series improves the way /usr filesystems are handled: tag
them appropriately, so later on we can find them and merge results they
contain directly back for the root filesystem.
The series includes also a new private debug API, and its usage to fix
the resolution of /dev/mapper/.. devices found in fstab; without it,
LVM /usr filesystems are not recognized as belonging to their roots.
Maybe a better API for this could be added, but since it's something
only related to the appliance then can stay internal for now. (Better
suggestions always welcome, of course.)
Thanks,
Pino Toscano (5):
inspect: change is_root flag into enum
inspect: mark CoreOS /usr partitions with own USR role
daemon: debug: new "exists" subcommand
inspect: fix existance check of /dev/mapper devices
inspect: gather info from /usr filesystems as well (RHBZ#1401474)

libguestfs and exporting to OVA/OVF
by Emmanuel Kasper
Hi
I've been looking for a standalone tool to create OVA/OVF VM files based
on a disk image and found none. So I was thinking to write my own.
Would you be interested in having such a tool in the libguestfs umbrella ?
My aim is too have a free toolchain to build VirtualBox images for
Debian (for Vagrant to be more exact, see
https://wiki.debian.org/Teams/Cloud/VagrantBaseBoxes)
Interface for such a tool would be something like
disk2ova --memory 2G --controller sata --network E1000
myDiskImage.{raw,qcow2}
based on the command line switches, a XML ovf would be created and
packed with the disk image in a OVA file.
There is some python code around which does that, for example the ganeti
export code and imagefactory
https://github.com/redhat-imaging/imagefactory/blob/master/imagefactory_p...
but nothing available as a standalone tool.
I am afraid I can only contribute Perl code.

[PATCH] appliance: mount also /dev/pts

Tools could require the use of pseudo-terminals, so make sure we have
/dev/pts available in the appliance. The "command" API already
bind-mounts it when running commands, so this is the only bit needed.

[PATCH v2] v2v: -o vdsm: Add --vdsm-compat-11 flag, -o rhev: Drop support for RHV < 4.1 (RHBZ#1400205).
by Richard W.M. Jones
Support for RHEV with RHEL 6 nodes required us to output the old style
qcow2 compat=0.10 images. Since RHEV 3.6 GA, RHEL 6 has not been
supported as a RHEV node type. Since RHV 4.1, compat=1.1 is supported.
Support for compat=1.1 is uncertain in RHV 4.0 even on RHEL 7 nodes.
There are significant downsides to using qcow2 compat=0.10 instead of
the modern default (compat=1.1).
Therefore this patch does two things:
For -o rhev, it drops support for compat=0.10 completely. You now
must use RHV 4.1.
For -o vdsm, it adds an interim flag (--vdsm-compat-11) which turns
off the previous behaviour. We can drop this flag later when all RHV
instances have moved to 4.1.
It also adds:
vdsm-compat-11-option
to the `virt-v2v --machine-readable' output to indicate that this flag
can be used.
Thanks: Yaniv Kaul, Michal Skrivanek.
