[PATCH 0/2] Delay firstboot scripts to some later time
by Tomáš Golembiovský
When firstboot is used from virt-v2v the scripts, if not fast enough, can get
killed by Windows. After windows installs virtio drivers injected by virt-v2v
it performs some internall reboot, stopping all the running services and
killing any running firstboot script. This is problem mostly for MSI installs
(like qemu-ga that was added recently) that can take several seconds to finish.
This change is little bit controversial in fact that it relies on powershell.
This is not available in early versions (without service packs) of XP and 2003
and our support matrix still mentions these Windows versions.
The change can also be problem for those who really wish to perform an action
early in the boot... if there are such users.

[PATCH libnbd 0/2] api: Add support for AF_VSOCK.
by Richard W.M. Jones
This is a series of patches to libnbd and nbdkit adding AF_VSOCK
support.
On the host side it allows you to start an nbdkit instance which
listens on a virtio-vsock socket:
$ ./nbdkit -fv --vsock memory 1G
...
nbdkit: debug: bound to vsock 2:10809
On the guest side you can then use libnbd to connect to the server:
$ ./run nbdsh -c 'h.connect_vsock(2, 10809)' -c 'print(h.get_size())'
1073741824
$ ./run nbdfuse mp --vsock 2 10809 &
$ ll mp/
total 0
-rw-rw-rw-. 1 rjones rjones 1073741824 Oct 18 16:23 nbd
$ dd if=/dev/random of=mp/nbd bs=1024 count=100 conv=notrunc,nocreat

(Performance of FUSE is not great, it should be better using raw
libnbd.)
I mainly wrote this to show that it can be done. It's unclear if this
would be faster or slower than the usual way that NBD devices are
exposed to guests via virtio-blk/-scsi.

[PATCH v2] launch: add support for autodetection of appliance image format
by Pavel Butsykin
This feature allows you to use different image formats for the fixed
appliance. The raw format is used by default.

[PATCH 0/2] Fixes and tweak to the installation of qemu-ga MSI

This, together with the changes to common repo are fixes to the installation
qemu-ga MSI.
There is still an issue that I did not figure yet how to fix. On Windows 10 it
fails to register the QEMU-GA service.

Unfortunately the --connect parameter doesn't let you access a disk on
a remote machine:
http://libguestfs.org/guestfs-faq.1.html#remote-libvirt-guests-cannot-be-...
It's not really possible the way you are doing it now. You will have
to run virt-df on the local machine. Perhaps use a tool like Ansible
(https://www.ansible.com/)?

[PATCH] rhv-upload: Fix waiting for transfer
by Nir Soffer
We were not considering failures while initializing the transfer. In
this case the transfer phase can change to PAUSED_SYSTEM or
FINISHED_FAILURE, and transfer_url will be None, which failed the
upload with a misleading error:
RuntimeError: direct upload to host not supported, requires
ovirt-engine >= 4.2 and only works when virt-v2v is run within the
oVirt/RHV environment, eg. on an oVirt node
Change the wait loop to consider all cases:
- Transfer failed and was removed
- Transfer failed and will be removed soon
- Transfer paused by the system (cancel required)
- Unexpected transfer phase (cancel required)
- Timeout waiting for TRANSFERRING state (cancel required)
Reported-by: Xiaodai Wang
---
I could easy simulate the case when the system paused the transfer by
injecting an error in vdsm, failing transfer initialization.
The import fail with:
nbdkit: python[1]: error: /home/nsoffer/src/virt-v2v/tmp/rhvupload.1DgXyh/rhv-upload-plugin.py: open: error: Traceback (most recent call last):
File "/home/nsoffer/src/virt-v2v/tmp/rhvupload.1DgXyh/rhv-upload-plugin.py", line 109, in open
transfer = create_transfer(connection, disk, host)
File "/home/nsoffer/src/virt-v2v/tmp/rhvupload.1DgXyh/rhv-upload-plugin.py", line 539, in create_transfer
"transfer %s was paused by system" % transfer.id)
RuntimeError: transfer 32b97384-ac8b-40d5-b423-26d31faabe32 was paused by system
I could not simulate the other cases. This probaly requires injecting
errors in engine.

[PATCH nbdkit v2 0/3] filters: stats: More useful, more friendly
by Nir Soffer
- Use more friendly output with GiB and MiB/s
- Measure time per operation, providing finer grain stats
- Add total stats for understanding system throughput
- Add missing stats for flush
I hope that these changes will help to understand and improve virt-v2v
performance.
Changes since v1:
- Keep bytes values
- Increase precision to 0.001 GiB and 0.001 MiB/s
- Add total stats
- Show time before size/rate for more consistent format
- Streamline using new record_stat() and print_stat()
v1 was here:
https://www.redhat.com/archives/libguestfs/2019-November/msg00345.html

1.39 proposal: Let's split up the libguestfs git repo and tarballs
by Richard W.M. Jones
My contention is that the libguestfs git repository is too large and
unwieldy. There are too many separate, unrelated projects and as a
result of that the source has too many dependencies and takes too long
to build and test.
The project divides (sort of) naturally into layers -- the library,
the bindings, the various virt tools -- and could be split along those
lines into separate projects which can then be released and evolve at
their own pace.
My suggested split would be something like this:
* libguestfs: The library, daemon and appliance. That would include
the following directories in a single project:
appliance
bash
contrib
daemon
docs
examples
gnulib
lib
logo
test-tool
tmp
utils
website
* 1 project for each language binding:
csharp
erlang
gobject
golang
haskell
java
lua
ocaml
php
perl
python
ruby
* virt-customize and related tools, we'd probably call this subproject
"virt-builder". It would include virt-builder, virt-customize and
virt-sysprep, since they share a lot of common code.
* 1 project for each of the following items:
small tools written in C
(virt-cat, virt-filesystems, virt-log, virt-ls, virt-tail,
virt-diff, virt-edit, virt-format, guestmount, virt-inspector,
virt-make-fs, virt-rescue)
guestfish
virt-alignment-scan and virt-df
virt-dib
virt-get-kernel
virt-resize
virt-sparsify
virt-v2v and virt-p2v
virt-win-reg
* I'd be inclined to drop the legacy Perl tools virt-tar,
virt-list-filesystems, virt-list-partitions unless someone
especially wished to step forward to maintain them.
* common code and generator: Off to the side we'd somehow need to
package up the common code and the generator for use by all of the
above projects. It wouldn't be a separate project for downstream
packagers, but instead the code would be included (ie. duplicated)
in tarballs and upstream available as a side git repo that you'd
need to include when building (git submodule?). This is somewhat
unspecified.
M4, PO, and tests would be split between the projects as appropriate.
My proposal would be to do this incrementally, rather than all at
once, moving the easier things out first.
Thoughts?
Rich.
