We already have a /var/lib/libvirt/images for OS install images.
We need a separate /var/lib/libvirt/filesystems for OS install
trees, since SELinux labelling will be different
* libvirt.spec.in: Add /var/lib/libvirt/filesystems
* src/Makefile.am: Create /var/lib/libvirt/filesystems
This adds support for a libvirt client configuration file
either /etc/libvirt/libvirt.conf for privileged clients,
or $HOME/.libvirt/libvirt.conf for unprivileged clients.
It allows one parameter
uri_aliases = [
"hail=qemu+ssh://root@hail.cloud.example.com/system",
"sleet=qemu+ssh://root@sleet.cloud.example.com/system",

Any call to virConnectOpen with a non-NULL URI will first
attempt to match against the uri_aliases list. An application
can disable this by using VIR_CONNECT_NO_ALIASES

when building libvirt in Fedora/s390x I've found that xenlight needs to
be explicitly disabled in the spec file. Configure properly sets the
library as non-existent, but the %files section still wants to package
the 3 /var/*/libvirt/libxl directories. See also
https://bugzilla.redhat.com/show_bug.cgi?id=745020
https://bugzilla.redhat.com/show_bug.cgi?id=740899 documents that
if qemu uses aio=native for its disks, then it consumes 128 aio
requests per disk. On a host with multiple guests, this can quickly
run out of kernel aio requests with the default aio-max-nr of
65536. Kernel developers have confirmed that there is no up-front
cost to raising this limit (a larger limit merely implies that more
aio requests can be issued in parallel, which in turn will result
in more kernel memory allocation, only if the system really does use
that many requests). Since the system default limit prevents 256
disks, which is well within libvirt's current scalability, this
patch installs a file to raise the limit and document it in case a
system administrator has further cause to tune the limit. The
install only works on platforms new enough to source /etc/sysctl.d/*
alongside /etc/sysctl.conf (F14 and RHEL 6).
* daemon/libvirtd.sysctl: New file.
* daemon/Makefile.am (EXTRA_DIST): Ship it.
(install-init, uninstall-init): Install it.
* libvirt.spec.in (%files): Include it in rpm.
Commit ecd8725c dropped attempts to probe the cgconfig service on
new enough Fedora where systemd took over that aspect of the system,
but mistakenly used F14 instead of F15 as the cutoff point.

Also, RHEL does not include HyperV support yet.
* libvirt.spec.in (with_cgconfig): Check cgconfig service in F15.
(%{?rhel}): Provide default for with_hyperv.
Inexplicably the sanlock code all got placed under the GPLv2-only,
so libvirt's use of sanlock introduces a license incompatibility.
The sanlock developers have now rearranged the code such that there
is a 'sanlock_client.so' which is LGPLv2+ while their daemon remains
GPLv2-only. To use the new client library we need to call the new
sanlock_init and sanlock_align APIs instead of sanlock_direct_init
and sanlock_direct_align. These APIs calls are now routed via the
sanlock daemon, instead of doing direct I/O calls to disk.
For all this we require sanlock >= 1.8
* configure.ac: Check for sanlock_client.so instead of sanlock.so
and fix various comments
* libvirt.spec.in: Mandate sanlock >= 1.8
* src/Makefile.am: Link to -lsanlock_client
* src/locking/lock_driver_sanlock.c: Use sanlock_init and
sanlock_align
https://bugzilla.redhat.com/show_bug.cgi?id=738725 documents that
'yum install libvirt' in Fedora 16 is rather noisy. This fixes
the problems.
* libvirt.spec.in (%post client): Silence chkconfig warning about
SysV services.
(%post) [with_cgconfig]: Drop for Fedora 15 and newer, where
systemd does this automatically.
This patch will probably cause merge conflicts to those trying
to do backports. The end goal is simple - domaincommon.rng
should be the state of domain.rng pre-patch, with a few lines
tweaked in the header, while domain.rng post-patch is now just
a shell that includes domaincommon.rng and sets the <start>.
* docs/schemas/domain.rng: Move guts...

The sanlock plugin for libvirt expects the directory
/var/lib/libvirt/sanlock to exist. Create this and add
it to the RPM
* libvirt.spec.in: Add /var/lib/libvirt/sanlock
* src/Makefile.am: Create /var/lib/libvirt/sanlock
virtPortProfiles are currently only used in the domain XML, but will
soon also be used in the network XML. To prepare for that change, this
patch moves the structure definition into util/network.h and the parse
and format functions into util/network.c (I decided that this was a
better choice than macvtap.h/c for something that needed to always be
available on all platforms).
We disable some drivers when building without libvirtd in configure,
but we do not do the same thing in libvirt.spec. It may break rpm
building without libvirtd.
domain.rng, network.rng, and interface.rng already use a few of the
same types (or in some cases *should* but don't), and an upcoming code
change will have them sharing even more. To prepare for that, this
patch takes those common data type definitions and moves them into
basictypes.rng.
This may break some rule about the need to RNG files to be autonomous
or something, but I saw that storageencryption.rng is used in this
way, so I figured it must not be completely against the law...
The current sanlock plugin requires a central management
application to manually add <lease> elements to each guest,
to protect resources that are assigned to it (eg writable
disks). This makes the sanlock plugin useless for usage
in more ad hoc deployment environments where there is no
central authority to associate disks with leases.
This patch adds a mode where the sanlock plugin will
automatically create leases for each assigned read-write
disk, using a md5 checksum of the fully qualified disk
path. This can work pretty well if guests are using
stable disk paths for block devices eg /dev/disk/by-path/XXXX
symlinks, or if all hosts have NFS volumes mounted in
a consistent pattern.
The plugin will create one lockspace for managing disks
with filename /var/lib/libvirt/sanlock/__LIBVIRT__DISKS__.
For each VM disks, there will be another file to hold
a lease /var/lib/libvirt/sanlock/5903e5d25e087e60a20fe4566fab41fd
Each VM disk lease is usually 1 MB in size. The script
virt-sanlock-cleanup should be run periodically to remove
unused lease files from the lockspace directory.
To make use of this capability the admin will need to do
several tasks:
- Mount an NFS volume (or other shared filesystem)
on /var/lib/libvirt/sanlock
- Configure 'host_id' in /etc/libvirt/qemu-sanlock.conf
with a unique value for each host with the same NFS
mount
- Toggle the 'auto_disk_leases' parameter in qemu-sanlock.conf
Technically the first step can be skipped, in which case
sanlock will only protect against 2 vms on the same host
using the same disk (or the same VM being started twice
due to error by libvirt).
* src/locking/libvirt_sanlock.aug,
src/locking/sanlock.conf,
src/locking/test_libvirt_sanlock.aug: Add config params
for configuring auto lease setup
* libvirt.spec.in: Add virt-sanlock-cleanup program, man

Introduce a configuration file with a single parameter
'require_lease_for_disks', which is used to decide whether
it is allowed to start a guest which has read/write disks,
but without any leases.

To install it, disable libvirtd sysv initscript:
chkconfig libvirtd off
service libvirtd stop
and enable libvirtd upstart job:
cp /usr/share/doc/libvirt-*/libvirtd.upstart \
/etc/init/libvirtd.conf
initctl reload-configuration
initctl start libvirtd
Test:
initctl status libvirtd
libvirtd start/running, process 3929
killall -9 libvirtd
initctl status libvirtd
libvirtd start/running, process 4047
I looked into the possibility to use the upstart script from Ubuntu or
at least getting inspiration from it but that's not possible. "expect
daemon" is a nice thing but it only works if the process is defined with
exec stanza instead of script ... no script. Unfortunately, with exec
stanza environment variables can only be set within upstart script
(i.e., configuration in /etc/sysconfig/libvirtd can't work). Hence, we
need to use script stanza, source sysconfig, and execute libvirtd
without --daemon. For similar reasons we can't use limit stanza and need
to handle DAEMON_COREFILE_LIMIT in job's script.

The Open Nebula driver has been unmaintained since it was first
introduced. The only commits have been for tree-wide cleanups.
It also has a major design flaw, in that it only knows about guests
that it has created itself, which makes it of very limited use.
Discussions wrt evolution of the VMWare ESX driver, concluded that
it should limit itself to single-node ESX operation and not try to
manage the multi-node architecture of VirtualCenter. Open Nebula
is a cluster like Virtual Center, not a single node system, so
the same reasoning applies.
The DeltaCloud project includes an Open Nebula driver and is a much
better fit architecturally, since it is explicitly targetting the
distributed multihost cluster scenario.
Thus this patch deletes the libvirt Open Nebula driver with the
recommendation that people use DeltaCloud for managing it instead.
* configure.ac: Remove probe for xmlrpc & --with-one arg

(with_esx): Fix esx build on RHEL 5, thanks to curl-devel rename.
Add a new xen driver based on libxenlight [1], which is the primary
toolstack starting with Xen 4.1.0. The driver is stateful and runs
privileged only.
Like the existing xen-unified driver, the libxenlight driver is
accessed with xen:// URI. Driver selection is based on the status
of xend. If xend is running, the libxenlight driver will not load
and xen:// connections are handled by xen-unified. If xend is not
running *and* the libxenlight driver is available, xen://
connections are deferred to the libxenlight driver.
V6:
- Address several code style issues noted by Daniel Veillard
- Make drive work with xen:/// URI
- Hold domain object reference while domain is injected in
libvirt event loop. Race found and fixed by Markus Groß.
V5:
- Ensure events are unregistered when domain private data
is destroyed. Discovered and fixed by Markus Groß.
V4:
- Handle restart of libvirtd, reconnecting to previously
started domains
- Rebased to current master
- Tested against Xen 4.1 RC7-pre (c/s 22961:c5d121fd35c0)
V3:
- Reserve vnc port within driver when autoport=yes
V2:
- Update to Xen 4.1 RC6-pre (c/s 22940:5a4710640f81)
- Rebased to current master
- Plug memory leaks found by Stefano Stabellini and valgrind
- Handle SHUTDOWN_crash domain death event

When building for an older distro, it's convenient to just
tell rpmbuild to define dist (for example, to .el6_0), rather

This fixes https://bugzilla.redhat.com/show_bug.cgi?id=609463
The problem was that, since a bridge always acquires the MAC address
of the connected interface with the numerically lowest MAC, as guests
are started and stopped, it was possible for the MAC address to change
over time, and this change in the network was being detected by
Windows 7 (it sees the MAC of the default route change), so on each
reboot it would bring up a dialog box asking about this "new network".
The solution is to create a dummy tap interface with a MAC guaranteed
to be lower than any guest interface's MAC, and attach that tap to the
bridge as soon as it's created. Since all guest MAC addresses start
with 0xFE, we can just generate a MAC with the standard "0x52, 0x54,
0" prefix, and it's guaranteed to always win (physical interfaces are
never connected to these bridges, so we don't need to worry about
competing numerically with them).
Note that the dummy tap is never set to IFF_UP state - that's not
necessary in order for the bridge to take its MAC, and not setting it
to UP eliminates the clutter of having an (eg) "virbr0-nic" displayed
in the output of the ifconfig command.
I chose to not auto-generate the MAC address in the network XML
parser, as there are likely to be consumers of that API that don't
need or want to have a MAC address associated with the
bridge.
Instead, in bridge_driver.c when the network is being defined, if
there is no MAC, one is generated. To account for virtual network
configs that already exist when upgrading from an older version of
libvirt, I've added a %post script to the specfile that searches for
all network definitions in both the config directory
(/etc/libvirt/qemu/networks) and the state directory
(/var/lib/libvirt/network) that are missing a mac address, generates a
random address, and adds it to the config (and a matching address to
the state file, if there is one).

The logging functions are enhanced so that immediately prior to
the first log message being printed to any output channel, the
libvirt package version will be printed.
eg
$ LIBVIRT_DEBUG=1 virsh
18:13:28.013: 17536: info : libvirt version: 0.8.7
18:13:28.013: 17536: debug : virInitialize:361 : register drivers
...
The 'configure' script gains two new arguments which can be
used as
--with-packager="Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10"
--with-packager-version="1.fc14"
to allow distros to append a custom string with package specific
data.
The RPM specfile is modified so that it appends the RPM version,
the build host, the build date and the packager name.
eg
$ LIBVIRT_DEBUG=1 virsh
18:14:52.086: 17551: info : libvirt version: 0.8.7, package: 1.fc13 (Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10)
18:14:52.086: 17551: debug : virInitialize:361 : register drivers
Thus when distro packagers receive bug reports they can clearly
see what version was in use, even if the bug reporter mistakenly
or intentionally lies about version/builds
* src/util/logging.c: Output version data prior to first log message
* libvirt.spec.in: Include RPM release, date, hostname & packager
* configure.ac: Add --with-packager & --with-packager-version args
When I build libvirt without libvirtd, I receive some errors:
cp: cannot stat `/home/wency/rpmbuild/BUILDROOT/libvirt-0.8.6-1.el6.x86_64/etc/libvirt/qemu/networks/default.xml': No such file or directory
My build step:
# ./autogen.sh --without-libvirtd
# make dist
# rpmbuild --nodeps --define "_sourcedir `pwd`" --define "_without_libvirtd 1" -ba libvirt.spec
The reason is we disable network when we do not build libvirt daemon in configure.ac.
After fixing this bug, I build libvirt without libvirtd, I receive other errors:

A number of the libvirt APIs require the use of cgroups. This is not
enabled by default on a RHEL6 install. After discussion with cgroups
team, it was decided that upon installation of the libvirt RPM, we
should automatically turn on the cgroups service. This will activate a
default configuration that turns on all cgroups controllers libvirt
requires for full operation.

Regression of forcing 0700 permissions (which breaks guest startup
because the qemu user can't see /var/lib/libvirt/*.monitor) was
introduced in commit 66823690e, as part of libvirt 0.8.2.
* libvirt.spec.in (%files): Drop %{_localstatedir}/lib/libvirt,
since libvirt depends on libvirt-client.
(%files client): Guarantee 755 permissions on
%(_localstatedir}/lib/libvirt, since the qemu user must be able to
do pathname resolution to a subdirectory.
Adds initial support for dtrace static probes in libvirtd
daemon, assuming use of systemtap dtrace compat shim on
Linux. The probes are inserted for network client connect,
disconnect, TLS handshake states and authentication protocol
states.
This can be tested by running the xample program and then
attempting to connect with any libvirt client (virsh,
virt-manager, etc).
# stap examples/systemtap/client.stp
Client fd=44 connected readonly=0
Client fd=44 auth polkit deny pid:24997,uid:500
Client fd=44 disconnected
Client fd=46 connected readonly=1
Client fd=46 auth sasl allow test
Client fd=46 disconnected
The libvirtd.stp file should also really not be required,
since it is duplicated info that is already available in
the main probes.d definition file. A script to autogenerate
the .stp file is needed, either in libvirtd tree, or better
as part of systemtap itself.

Integrate with libaudit.so for auditing of important operations.
libvirtd gains a couple of config entries for auditing. By
default it will enable auditing, if its enabled on the host.
It can be configured to force exit if auditing is disabled
on the host. It will can also send audit messages via libvirt
internal logging API

macro to report data. This is a no-op unless auditing is
enabled

Vdsm needs to communicate with its guest agent via unix domain socket,
which qemu creates due to the following domain xml device:
<channel type='unix'>
<target type='virtio' name='com.redhat.rhevm.vdsm'/>
<source mode='bind' path='/var/lib/libvirt/qemu/channels/fcp-xp-1.com.redhat.rhevm.vdsm'/>
</channel>
The location of the socket below /var/lib/libvirt/qemu/channels makes
sense, to humans and selinux policy alike. However, that socket should
be accessible to vdsm, too.
Due to other (storage) reasons, vdsm is to join the "qemu" group. With
this patch, vdsm can look below /var/lib/libvirt/qemu and connect to the
socket.
The socket itself should be chmod'ed to allow qemu group read/write, but
that's for another project.
BZ#643407
--dhcp-no-override description from dnsmasq man page:
Disable re-use of the DHCP servername and filename fields as
extra option space. If it can, dnsmasq moves the boot server and
filename information (from dhcp-boot) out of their dedicated
fields into DHCP options. This make extra space available in the
DHCP packet for options but can, rarely, confuse old or broken
clients. This flag forces "simple and safe" behaviour to avoid
problems in such a case.
It seems some virtual network card ROMs are this old/buggy so let's add
--dhcp-no-override as a workaround for them. We don't use extra DHCP
options so this should be safe. The option was added in dnsmasq-2.41,
which becomes the minimum required version.
This patch removes the individual author names from the libvirtd and virsh
man pages, instead referring to the main AUTHORS file distributed with
libvirt. This approach is needed, as we can't guarantee unicode support
across all versions of pod2man used with libvirt.
Additionally, this patch includes the libvirtd man page in the spec file
used with "make rpm". Without this patch "make rpm" is broken.
Firstly, the init script has to touch its file under /var/lock/subsys
when started, otherwise the system would think it's not running and
won't stop it during shutdown.
Secondly, for some reason there is a policy to automatically enable
init scripts when they are installed, so let the specfile do this. We
also need to start the init script to ensure it will be stopped during
the first shutdown after installing the package.
Also $LISTFILE should be enclosed by quotes everywhere as suggested by
Eric.
This patch introduces a dependency on libnl, which subsequent patches
will then use.
Changes from V1 to V2:
- added diffstats
- following changes in tree
Example output during shutdown:
Running guests on default URI: console, rhel6-1, rhel5-64
Running guests on lxc:/// URI: lxc-shell
Running guests on xen:/// URI: error: no hypervisor driver available for xen:///
error: failed to connect to the hypervisor
Running guests on vbox+tcp://orkuz/system URI: no running guests.
Suspending guests on default URI...
Suspending console: done
Suspending rhel6-1: done
Suspending rhel5-64: done
Suspending guests on lxc:/// URI...
Suspending lxc-shell: error: Failed to save domain 9cba8bfb-56f4-6589-2d12-8a58c886dd3b state
error: this function is not supported by the hypervisor: virDomainManagedSave
Note, the "Suspending $guest: " shows progress during the suspend phase
if domjobinfo gives meaningful output.
Example output during boot:
Resuming guests on default URI...
Resuming guest rhel6-1: done
Resuming guest rhel5-64: done
Resuming guest console: done
Resuming guests on lxc:/// URI...
Resuming guest lxc-shell: already active
Configuration used for generating the examples above:
URIS='default lxc:/// xen:/// vbox+tcp://orkuz/system'
The script uses /var/lib/libvirt/libvirt-guests files to note all active
guest it should try to resume on next boot. It's content looks like:
default 7f8b9d93-30e1-f0b9-47a7-cb408482654b 085b4c95-5da2-e8e1-712f-6ea6a4156af2 fb4d8360-5305-df3a-2da1-07d682891b8c
lxc:/// 9cba8bfb-56f4-6589-2d12-8a58c886dd3b
Add ebtables,iptables & iptables-ipv6 dependency to rpm.
Changes from V1 to V2:
-passing --without-libpcap to configure script, if libpcap is not to be used
This includes various things:
- fix the Requires: libvirt-client to use %{name} to allow easy
renaming
- when building ESX support one need libcurl-devel
- remove Makefile[.in] from xml/nwfilter in the docs, as this breaks
parallel install ation of i686 and x86_64 packages
- don't include nwfilter config files if not building with the daemon
all relatively trivial which is why I packed them together
* libvirt.spec.in: fix various small bugs
use /var/lib/libvirt/dnsmasq since /var/lib/libvirt/network is
unreadable by the dnsmasq binary
* src/network/bridge_driver.c: update DNSMASQ_STATE_DIR
* src/Makefile.am: create it on make install
* libvirt.spec.in: take the new directory into account
To ensure that patches in the RPM don't break any functionality
it is neccessary to run the test suites during build. It currently
has 3 tests disabled
- daemon-conf: this is totally broken, since it relies on
being able to resolve the 'libvirt' group & being able to
resolve hostnames at daemon startup. This isn't possible
in a mock build root
- seclabeltest: fails to initialize selinux in the mock
build root. Possibly fixable
- nodeinfotest: broken on s390 + ppc - this is a real bug
* libvirt.spec.in: Add a %check section, with 3 tests
temporarily disabled
* configure.ac docs/news.html.in libvirt.spec.in src/libvirt_public.syms:
updates for release of 0.8.0
* po/*.po po/libvirt.pot: updated a lar set of localizations, and merge
the messages
This patch implements support for learning a VM's IP address. It uses
the pcap library to listen on the VM's backend network interface (tap)
or the physical ethernet device (macvtap) and tries to capture packets
with source or destination MAC address of the VM and learn from DHCP
Offers, ARP traffic, or first-sent IPv4 packet what the IP address of
the VM's interface is. This then allows to instantiate the network
traffic filtering rules without the user having to provide the IP
parameter somewhere in the filter description or in the interface
description as a parameter. This only supports to detect the parameter
IP, which is for the assumed single IPv4 address of a VM. There is not
support for interfaces that may have multiple IP addresses (IP
aliasing) or IPv6 that may then require more than one valid IP address
to be detected. A VM can have multiple independent interfaces that each
uses a different IP address and in that case it will be attempted to
detect each one of the address independently.
So, when for example an interface description in the domain XML has
looked like this up to now:
<interface type='bridge'>
<source bridge='mybridge'/>
<model type='virtio'/>
<filterref filter='clean-traffic'>
<parameter name='IP' value='10.2.3.4'/>
</filterref>
</interface>
you may omit the IP parameter:
<interface type='bridge'>
<source bridge='mybridge'/>
<model type='virtio'/>
<filterref filter='clean-traffic'/>
</interface>
Internally I am walking the 'tree' of a VM's referenced network filters
and determine with the given variables which variables are missing. Now,
the above IP parameter may be missing and this causes a libvirt-internal
thread to be started that uses the pcap library's API to listen to the
backend interface (in case of macvtap to the physical interface) in an
attempt to determine the missing IP parameter. If the backend interface
disappears the thread terminates assuming the VM was brought down. In
case of a macvtap device a timeout is being used to wait for packets
from the given VM (filtering by VM's interface MAC address). If the VM's
macvtap device disappeared the thread also terminates. In all other
cases it tries to determine the IP address of the VM and will then apply
the rules late on the given interface, which would have happened
immediately if the IP parameter had been explicitly given. In case an
error happens while the firewall rules are applied, the VM's backend
interface is 'down'ed preventing it to communicate. Reasons for failure
for applying the network firewall rules may that an ebtables/iptables
command failes or OOM errors. Essentially the same failure reasons may
occur as when the firewall rules are applied immediately on VM start,
except that due to the late application of the filtering rules the VM
now is already running and cannot be hindered anymore from starting.
Bringing down the whole VM would probably be considered too drastic.
While a VM's IP address is attempted to be determined only limited
updates to network filters are allowed. In particular it is prevented
that filters are modified in such a way that they would introduce new
variables.
A caveat: The algorithm does not know which one is the appropriate IP
address of a VM. If the VM spoofs an IP address in its first ARP traffic
or IPv4 packets its filtering rules will be instantiated for this IP
address, thus 'locking' it to the found IP address. So, it's still
'safer' to explicitly provide the IP address of a VM's interface in the
filter description if it is known beforehand.
* configure.ac: detect libpcap
* libvirt.spec.in: require libpcap[-devel] if qemu is built
* src/internal.h: add the new ATTRIBUTE_PACKED define
* src/Makefile.am src/libvirt_private.syms: add the new modules and symbols
* src/nwfilter/nwfilter_learnipaddr.[ch]: new module being added
* src/nwfilter/nwfilter_driver.c src/conf/nwfilter_conf.[ch]
src/nwfilter/nwfilter_ebiptables_driver.[ch]
src/nwfilter/nwfilter_gentech_driver.[ch]: plu the new functionality in
* tests/nwfilterxml2xmltest: extend testing
This patch adds a relaxng nwfilter schema along with a test that
verifies all the test output XML against the schema. The input XMLs
contain a lot of intentional out-of-range values that make them fail the
schema verification, so I am not verifying against those.
* cfg.mk (sc_prohibit_test_minus_ao): Also check for [.
* docs/Makefile.am (%.html, html/index.html): Avoid non-portable
test usage.
* libvirt.spec.in (%post): Likewise.
* tools/virt-pki-validate.in (servercert.pem): Likewise.
* configure.ac (LOGNAME): Use test, not [, in files processed by
autoconf.
Detected by Matthias Bolte.
* examples/xml/nwfilter/Makefile.am: add all xml to the distribution
* libvirt.spec.in: reference them from the rpm spec file to have them
available in the main libvirt package
Having a single logrotate configuration file for all hypervisors
did not work as logrotate would get confused if an hypervisor not
supported on that platform was still listed. Simplest is to split
the logrotate as separate per hypervisor files and change the
spec file to only install the ones compiled in.
* daemon/libvirtd.lxc.logrotate.in daemon/libvirtd.qemu.logrotate.in
daemon/libvirtd.uml.logrotate.in: copy and split the original
daemon/libvirtd.logrotate.in file
* daemon/Makefile.am: update to support the different files and
cleanup in sed suggested by Eric Blake
* libvirt.spec.in: only install the relevant logrotate configs
* daemon/.gitignore: update logrotate generated list
* configure.ac libvirt.spec.in: update with new version
* docs/news.html.in: add list of changes in 0.7.7
* po/*po*: updated spanish and russian localisations, rebuilt
Create the filesystem on the partition used by the pool
* configure.ac: check for mkfs availability
* libvirt.spec.in: add extra require on util-linux for mkfs
* src/storage/storage_backend_fs.c: run mkfs with the expected
fs type when creating a filesystem pool
