[libvirt] Supporting vhost-net and macvtap in libvirt for QEMU
by Anthony Liguori
Disclaimer: I am neither an SR-IOV nor a vhost-net expert, but I've CC'd
people that are who can throw tomatoes at me for getting bits wrong :-)
I wanted to start a discussion about supporting vhost-net in libvirt.
vhost-net has not yet been merged into qemu but I expect it will be soon
so it's a good time to start this discussion.
There are two modes worth supporting for vhost-net in libvirt. The
first mode is where vhost-net backs to a tun/tap device. This is
behaves in very much the same way that -net tap behaves in qemu today.
Basically, the difference is that the virtio backend is in the kernel
instead of in qemu so there should be some performance improvement.
Current, libvirt invokes qemu with -net tap,fd=X where X is an already
open fd to a tun/tap device. I suspect that after we merge vhost-net,
libvirt could support vhost-net in this mode by just doing -net
vhost,fd=X. I think the only real question for libvirt is whether to
provide a user visible switch to use vhost or to just always use vhost
when it's available and it makes sense. Personally, I think the later
makes sense.
The more interesting invocation of vhost-net though is one where the
vhost-net device backs directly to a physical network card. In this
mode, vhost should get considerably better performance than the current
implementation. I don't know the syntax yet, but I think it's
reasonable to assume that it will look something like -net
tap,dev=eth0. The effect will be that eth0 is dedicated to the guest.
On most modern systems, there is a small number of network devices so
this model is not all that useful except when dealing with SR-IOV
adapters. In that case, each physical device can be exposed as many
virtual devices (VFs). There are a few restrictions here though. The
biggest is that currently, you can only change the number of VFs by
reloading a kernel module so it's really a parameter that must be set at
startup time.
I think there are a few ways libvirt could support vhost-net in this
second mode. The simplest would be to introduce a new tag similar to
<source network='br0'>. In fact, if you probed the device type for the
network parameter, you could probably do something like <source
network='eth0'> and have it Just Work.
Another model would be to have libvirt see an SR-IOV adapter as a
network pool whereas it handled all of the VF management. Considering
how inflexible SR-IOV is today, I'm not sure whether this is the best model.
Has anyone put any more thought into this problem or how this should be
modeled in libvirt? Michael, could you share your current thinking for
-net syntax?

[libvirt] [PATCH] Fix reporting of i/o errors by iohelper process
by Jason J. Herne
From: "Jason J. Herne" <jjherne(a)us.ibm.com>
libvirt_iohelper is a helper process that is exec'ed and used to handle I/O
during a Qemu managed save operation. Due to a missing call to
virFileWrapperFdClose, all I/O error messages reported by iohelper are lost.
This patch adds a call to virFileWrapperFdClose to the cleanup phase of
qemuDomainSaveMemory.
This patch also modifies virFileWrapperFdClose such that errors are only
reported when the length of the err_msg buffer is > 0. Before now, the
existence of the buffer would trigger error reporting in virFileWrapperFdClose.

[libvirt] ANNOUNCE: libguestfs 1.26 released
by Richard W.M. Jones
I'm pleased to announce libguestfs 1.26, a library and set of tools
for accessing and modifying virtual machine disk images. This release
took more than 6 months of work by a considerable number of people,
and has many new features (see release notes below).
You can get libguestfs 1.26 here:
Main website: http://libguestfs.org/
Source: http://libguestfs.org/download/1.26-stable/
You will also need latest supermin from here:
http://libguestfs.org/download/supermin/
Fedora 20/21: http://koji.fedoraproject.org/koji/packageinfo?packageID=8391
It will appear as an update for F20 in about a week.
Debian/experimental coming soon, see:
https://packages.debian.org/experimental/libguestfs0
The Fedora and Debian packages have split dependencies so you can
download just the features you need.
>From http://libguestfs.org/guestfs-release-notes.1.html :
RELEASE NOTES FOR LIBGUESTFS 1.26
New features
Tools
virt-customize(1) is a new tool for customizing virtual machine disk
images. It lets you install packages, edit configuration files, run
scripts, set passwords and so on. virt-builder(1) and virt-sysprep(1)
use virt-customize, and command line options across all these tools are
now identical.
virt-diff(1) is a new tool for showing the differences between the
filesystems of two virtual machines. It is mainly useful when showing
what files have been changed between snapshots.
virt-builder(1) has been greatly enhanced. There are many more ways to
customize the virtual machine. It can pull templates from multiple
repositories. A parallelized internal xzcat implementation speeds up
template decompression. Virt-builder uses an optimizing planner to
choose the fastest way to build the VM. It is now easier to use
virt-builder from other programs. Internationalization support has been
added to metadata. More efficient SELinux relabelling of files. Can
build guests for multiple architectures. Error messages have been
improved. (Pino Toscano)
virt-sparsify(1) has a new --in-place option. This sparsifies an image
in place (without copying it) and is also much faster. (Lots of help
provided by Paolo Bonzini)
virt-sysprep(1) can delete and scrub files under user control. You can
lock user accounts or set random passwords on accounts. Can remove more
log files. Can unsubscribe a guest from Red Hat Subscription Manager.
New flexible way to enable and disable operations. (Wanlong Gao, Pino
Toscano)
virt-win-reg(1) allows you to use URIs to specify remote disk images.
virt-format(1) can now pass the extra space that it recovers back to
the host.
guestfish(1) has additional environment variables to give fine control
over the ><fs> prompt. Guestfish reads its (rarely used) configuration
file in a different order now so that local settings override global
settings. (Pino Toscano)
virt-make-fs(1) was rewritten in C, but is unchanged in terms of
functionality and command line usage.
Language bindings
The OCaml bindings have a new Guestfs.Errno module, used to check the
error number returned by Guestfs.last_errno.
PHP tests now work. (Pino Toscano)
Inspection
Inspection can recognize Debian live images.
Architectures
ARMv7 (32 bit) now supports KVM acceleration.
Aarch64 (ARM 64 bit) is supported, but the appliance part does not work
yet.
PPC64 support has been fixed and enhanced.
Security
Denial of service when inspecting disk images with corrupt btrfs
volumes
It was possible to crash libguestfs (and programs that use libguestfs
as a library) by presenting a disk image containing a corrupt btrfs
volume.
This was caused by a NULL pointer dereference causing a denial of
service, and is not thought to be exploitable any further.
See commit d70ceb4cbea165c960710576efac5a5716055486 for the fix. This
fix is included in libguestfs stable branches ≥ 1.26.0, ≥ 1.24.6 and
≥ 1.22.8, and also in RHEL ≥ 7.0. Earlier versions of libguestfs are
not vulnerable.
Better generation of random root passwords and random seeds
When generating random root passwords and random seeds, two bugs were
fixed which are possibly security related. Firstly we no longer read
excessive bytes from /dev/urandom (most of which were just thrown
away). Secondly we changed the code to avoid modulo bias. These
issues were not thought to be exploitable. (Both changes suggested by
Edwin Török)
API
GUID parameters are now validated when they are passed to API calls,
whereas previously you could have passed any string. (Pino Toscano)
New APIs
guestfs_add_drive_opts: new discard parameter
The new discard parameter allows fine-grained control over
discard/trim support for a particular disk. This allows the host file
to become more sparse (or thin-provisioned) when you delete files or
issue the guestfs_fstrim API call.
guestfs_add_domain: new parameters: cachemode, discard
These parameters are passed through when adding the domain's disks.
guestfs_blkdiscard
Discard all blocks on a guestfs device. Combined with the discard
parameter above, this makes the host file sparse.
guestfs_blkdiscardzeroes
Test if discarded blocks read back as zeroes.
guestfs_compare_*
guestfs_copy_*
For each struct returned through the API, libguestfs now generates
guestfs_compare_* and guestfs_copy_* functions to allow you to
compare and copy structs.
guestfs_copy_attributes
Copy attributes (like permissions, xattrs, ownership) from one file
to another. (Pino Toscano)
guestfs_disk_create
A flexible API for creating empty disk images from scratch. This
avoids the need to call out to external programs like qemu-img(1).
guestfs_get_backend_settings
guestfs_set_backend_settings
Per-backend settings (can also be set via the environment variable
LIBGUESTFS_BACKEND_SETTINGS). The main use for this is forcing TCG
mode in the qemu-based backends, for example:
export LIBGUESTFS_BACKEND=direct
export LIBGUESTFS_BACKEND_SETTINGS=force_tcg
guestfs_part_get_name
Get the label or name of a partition (for GPT disk images).
Build changes
The following extra packages are required to build libguestfs 1.26:
supermin ≥ 5
Supermin version 5 is required to build this version of libguestfs.
flex, bison
Virt-builder now uses a real parser to parse its metadata file, so
these tools are required.
xz
This is now a required build dependency, where previously it was (in
theory) optional.
Internals
PO message extraction rewritten to be more robust. (Pino Toscano)
podwrapper gives an error if the --insert or --verbatim argument
pattern is not found.
Libguestfs now passes the qemu -enable-fips option to enable FIPS, if
qemu supports it.
./configure --without-qemu can be used if you don't want to specify a
default hypervisor.
Copy-on-write [COW] overlays, used for example for read-only drives,
are now created through an internal backend API (.create_cow_overlay).
Libvirt backend uses some funky C macros to generate XML. These are
simpler and safer.
The ChangeLog file format has changed. It is now just the same as git
log, instead of using a custom format.
Appliance start-up has changed:
* The libguestfs appliance now initializes LVM the same way as it is
done on physical machines.
* The libguestfs appliance does not write an empty string to
/proc/sys/kernel/hotplug when starting up.
Note that you must configure your kernel to have
CONFIG_UEVENT_HELPER_PATH="" otherwise you will get strange LVM
errors (this applies as much to any Linux machine, not just
libguestfs). (Peter Rajnoha)
Libguestfs can now be built on arches that have ocamlc(1) but not
ocamlopt(1). (Hilko Bengen, Olaf Hering)
You cannot use ./configure --disable-daemon --enable-appliance. It made
no sense anyway. Now it is expressly forbidden by the configure script.
The packagelist file uses m4 for macro expansion instead of cpp.

[libvirt] [libvirt-java] [PATCH 00/65]
by Claudio Bley
Hi.
Here are a few patches that piled up in my local branch. Some of them
I already submitted to this list, but there has been no reponse to
them.
Included are a few trivial fixes as well as memory leak fixes and
additions to the public API.
There had been some minor interest in my first version of domain event
support in the Java wrapper[1], which I have reworked almost entirely.
If nobody objects, say, within the next two weeks or so, I'll go ahead
and push the whole series as was suggested to me by Daniel P. Berrange
on this list[2].
I've made sure that all JUnit tests pass after every commit with JNA
versions 3.4.1, 3.4.2, 3.5.0, 3.5.1, 3.5.2 and 4.0.0.
I'd really appreciate your comments or suggestions.
Thanks!

[libvirt] [PATCHv2 0/4] Another attempt at improving virsh autocompletion
by Solly Ross
Version 2: Electric Boogaloo
Version 1: https://www.redhat.com/archives/libvir-list/2014-March/msg01898.html
This version of the patch introduces the following new things:
- Tests (a whole bunch of them, in fact)!
- A new `complete` command to run get newline-separated
completion results from the command line
- Support for completing partial quotes
(e.g. `virsh complete "fake-command ab \"i "`)
- Passing the syntax checks (sorry about that)
A brief overview of the patch set follows:
1. Extract parsing logic from the vshCommandParse
so that it can be used elsewhere. The new method
returns states and sets passed in pointers. Calling
methods can interpret these states and deal with them
as needed (completion ignores many, while
vshCommandParse throws errors).
2. Implement (and test!) an improved completion
engine with support for virsh quoting rules,
flags, positional arguments, no duplication,
and more.
3. Add (and test!) a method for retrieve a global
vshControl object should readline be enabled. This
allows for "smart completion" of options like "domain".
4. Extract the domain listing code from virsh-domain-monitor,
and move it to virsh-completer. Implement a domain completer,
which is then used for all the cases of "domain" options
(note that it current does not have any flags specified for
which commands should list active vs inactive domains,
as this commit is mainly to allow people to test out
"smart completion")
Solly Ross (4):
Improve virsh autocompletion (extract parser)
Improve virsh autocompletion (base framework)
Improve virsh autocompletion (global ctl object)
Improve virsh autocompletion (domain completer)
