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.

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.

This commit breaks libvirt-lxc.
libvirt does in lxcContainerMountBasicFS():
/*
* We can't immediately set the MS_RDONLY flag when mounting filesystems
* because (in at least some kernel versions) this will propagate back
* to the original mount in the host OS, turning it readonly too. Thus
* we mount the filesystem in read-write mode initially, and then do a
* separate read-only bind mount on top of that.
*/
bindOverReadonly = !!(mnt_mflags & MS_RDONLY);

if (mount(mnt_src, mnt->dst, mnt->type, mnt_mflags &
~MS_RDONLY, NULL) < 0) {
^^^^ Here it fails for sysfs because with user namespaces we bind the
existing /sys into the container
and would have to read out all existing mount flags from the current /sys mount.
Otherwise mount() fails with EPERM.
On my test system /sys is mounted with
"rw,nosuid,nodev,noexec,relatime" and libvirt
misses the realtime...
virReportSystemError(errno,
_("Failed to mount %s on %s type %s flags=%x"),

}
if (bindOverReadonly &&
mount(mnt_src, mnt->dst, NULL,

^^^ Here it fails because now we'd have to specify all flags as used
for the first
mount. For the procfs case MS_NOSUID|MS_NOEXEC|MS_NODEV.
See lxcBasicMounts[].
In this case the fix is easy, add mnt_mflags to the mount flags.

[libvirt] [RFC: PATCH 0/2] Display allocation during dumpxml
by Eric Blake
I'm still working on code to populate the latest numbers for
each disk of a domain, including getting numbers for offline
domains, but have confirmed that with these two patches alone
I'm able to see <capacity> and <allocation> numbers for block
volumes of live domains (thanks to how we populate backing
chain information). So while there are more patches to come,
I'd like to get review started on my proposed API addition.

[libvirt] [PATCH v3] leaseshelper: improvements to support all events
by Nehal J Wani
This patch enables the helper program to detect event(s) triggered when there
is a change in lease length or expiry and client-id. This transfers complete
control of leases database to libvirt and obsoletes use of the lease database
file (<network-name>.leases). That file will not be created, read, or written.
This is achieved by adding the option --leasefile-ro to dnsmasq and passing a
custom env var to leaseshelper, which helps us map events related to leases
with their corresponding network bridges, no matter what the event be.
Also, this requires the addition of a new non-lease entry in our custom lease
database: "server-duid". It is required to identify a DHCPv6 server.
Now that dnsmasq doesn't maintain its own leases database, it relies on our
helper program to tell it about previous leases and server duid. Thus, this
patch makes our leases program honor an extra action: "init", in which it sends
the known info in a particular format to dnsmasq by printing it to stdout.
---
This is compatible with libvirt 1.2.6 as only additions have been
introduced, and the old leases file (*.status) will still be supported.
v3: * Add server-duid as an entry in the lease object for every ipv6 lease.
* Remove unnecessary variables and double copies.
* Take value from DNSMASQ_OLD_HOSTNAME if hostname is not known.

[libvirt] [PATCH] lxc: fix setmem effect on a running LXC machine
by Erik Skultety
When user calls setmem on a running LXC machine, we do update its cgroup
entry (which is in odds with the original bug report, possibly resolved
by later versions), however we neither update domain's runtime XML nor
we update our internal structures and this patch fixes it.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1131919

[libvirt] [PATCH] network: Add bandwidth support to ethernet interface
by Anirban Chakraborty
Ethernet interfaces in libvirt currently do not support bandwidth setting.
For example, following xml file for an interface will not apply these
settings to corresponding qdiscs.
<interface type="ethernet">
<mac address="02:36:1d:18:2a:e4"/>
<model type="virtio"/>
<script path=""/>
<target dev="tap361d182a-e4"/>
<bandwidth>
<inbound average="984" peak="1024" burst="64"/>
<outbound average="2000" peak="2048" burst="128"/>
</bandwidth>
</interface>

[libvirt] [PATCH v6 0/7] qemu: Introduce support for new the block_set_io_throttle parameters add in the version 1.7 of qemu.
by Matthias Gatto
This series of patches add support for bps_max, bps_rd_max, bps_wr_max,
bps_max, bps_rd_max, bps_wr_max, and iops_size in the functions qemuDomainSetBlockIoTune
and qemuDomainGetBlockIoTune.
The last patch add support for these parameters to the virsh blkdeviotune command.
v2: -Spellfix
v3: -Merge patch 1/9,2/9,5/9 together.
-Change the capability detection.(patch 2/7 and 3/7).
-Try to make the usage of QEMU_NB_BLOCK_IO_TUNE_PARAM_MAX more explicit(patch 3/7).
v4: -Rebase on HEAD.
-Update qemu_driver to comply with Pavel's patchs.(patch 3/6)
-Remove the qemu_monitor_text modification.(remove old patch 5/7)
v5: -Split patch 1/6 in two.
-Add documentation for the new xml options (patch 2/7)
-Change (void) to ATTRIBUTE_UNUSED (patch 4/7)
-Capability detection of supportMaxOptions move before usage of supportMaxOptions (patch 4/7)
v6: -Spellfix
-Add comment (patch 4/7, 5/7)
-Undo the modification of the supportMaxOptions made
in the v5 because it was creating bugs(patch 4/5)
The 2 first patches have been reviewed by Eric Blake and sould be merge soon
The 3rd patch have been reviewed by Michal Privoznik and ack
Matthias Gatto (7):
qemu: Add define for the new throttle options
qemu: Modify the structure _virDomainBlockIoTuneInfo.
qemu: Add Qemu capability for bps_max and friends
qemu: Add bps_max and friends qemu driver
qemu: Add bps_max and friends QMP suport
qemu: Add bps_max and friends to qemu command generation
virsh: Add bps_max and friends to virsh
