This patch converts the Xen libxl driver to support only Xen >= 4.2.
Support for Xen 4.1 libxl is dropped since that version of libxl is
designated 'technology preview' only and is incompatible with Xen 4.2
libxl. Additionally, the default toolstack in Xen 4.1 is still xend,
for which libvirt has a stable, functional driver.

In older Fedora, the spec file for libivrt depended on avahi, which
included avahi-daemon, which in turn depended on dbus. But now that
avahi libs and avahi-daemon are (correctly) in separate pacakges,
and since we REALLY don't want a mandatory dependency on avahi-daemon,
and considering that our init scripts require the messagebus service
from dbus, we need to explicitly require dbus ourselves.
* libvirt.spec.in (Requires): Add dbus for libvirt-daemon.
Implement the domainManagedSave, domainHasManagedSaveImage, and
domainManagedSaveRemove functions in the libvirt legacy xen driver.
domainHasManagedSaveImage check the managedsave image from filesystem
everytime. This is different from qemu and libxl driver. In qemu or
libxl driver, there is a hasManagesSave flag in virDomainObjPtr which
is not used in xen legacy driver. This flag could not add into xen
driver ptr either, because the driver ptr will be released at the end of
every libvirt api call. Meanwhile, AFAIK, xen store all the flags in
xen not in libvirt xen driver. There is no need to add this flag in xen.

In Fedora 16, we quit enabling cgconfig because systemd set up
default cgroups that were good enough for our use. But in F17,
when we switched to systemd, we reverted and started up cgconfig
again. See also the tail of this thread:

This should not make a big difference in real world since libvirt-daemon,
which is already required by libvirt-lock-sanlock, requires
libvirt-client and thus libvirt-lock-sanlock gets this dependency
transitively. However, since libvirt-lock-sanlock contains
sanlock_helper binary linked to libvirt.so, we should start requiring
libvirt-client directly.
The previous commit was incomplete. We need to also add explicit
Requires for the newer version since RPM's automatic dependencies won't
work with sanlock.
libssh2 unfortunately doesn't support symbol versioning so RPM can't
figure out what version is needed for the currently installed libvirt
package. This patch adds a runtime requirement, so that the correct
version of libssh2 can be installed along with libvirt.
Libssh2 transport support was enabled lately but the spec file wasn't
updated to take this into account. This caused libvirt to be built
without libssh2 support in Red Hat based OSes.
While the changes to sanlock driver should be stable, the actual
implementation of sanlock_helper is supposed to be replaced in the
future. However, before we can implement a better sanlock_helper, we
need an administrative interface to libvirtd so that the helper can just
pass a "leases lost" event to the particular libvirt driver and
everything else will be taken care of internally. This approach will
also allow libvirt to pass such event to applications and use
appropriate reasons when changing domain states.
The temporary implementation handles all actions directly by calling
appropriate libvirt APIs (which among other things means that it needs
to know the credentials required to connect to libvirtd).
I noticed that in two places, we require util-linux, and in a third,
we require util-linux-ng. On Fedora (I tested F15 through rawhide),
util-linux-ng is obsoleted by util-linux; on RHEL 6, util-linux
is obsoleted by util-linux-ng. That is, on either platform, either
name will get you the correct package installed (where the preferred
name on fedora is util-linux, and on RHEL 6 is util-linux-ng). But
on RHEL 5, there is no util-linux-ng
* libvirt.spec.in (Requires): Use util-linux, not util-linux-ng.
The Fedora policies don't want us installing the legacy initscripts
in parallel with the systemd ones, so switch to only install the
systemd unit

Based exclusively on work by Eric Blake in a patch posted with the same
subject. However some modifications related to comments and my plans to
add another backend.
Added WITH_INTERFACE as the only automake variable deciding whether to
build the driver and using WITH_NETCF to identify that we're wanting to
use the netcf library as the backend.
* configure.ac: Added with_interface
* src/interface/netcf_driver.c: Renamed..
* src/interface/interface_backend_netcf.c: ..to this to match storage.
* src/interface/netcf_driver.h: Renamed..
* src/interface/interface_driver.h: ..to this.
* daemon/Makefile.am: Respect WITH_INTERFACE and WITH_NETCF.
* libvirt.spec.in: Add RPM support for --with-interface
When building RPMs the host kernel cannot be assumed to match
the target OS kernel. Thus auto-detecting /selinux vs
/sys/fs/selinux based on the host kernel can result in the
wrong choice (eg F18 builds on a RHEL6 host kernel)

A previous patch forced libnl-3 and netcf-0.2.2 (which itself requires
libnl-3) when *building* for Fedora 18+ (and RHEL 7+), but the
install-time Requires: for netcf has always been implicit due to
libvirtd linking with libnetcf.so. However, the since the API of netcf
didn't change when it was rebuilt to use libnl-3, the internal library
version didn't change either, making it possible (from rpm's point of
view) to upgrade libvirt without upgrading netcf (in reality, that
leads to a segfault - see
https://bugzilla.redhat.com/show_bug.cgi?id=853381).
The solution is to put an explicit Requires: line in libvirt's
specfile for fedora >= 18 and rhel >= 7.
The libvirt storage driver uses librbd.so for its functionality.
RPM will automatically add a dependency on the library, so there
is no need to have an explicit dependency on the ceph RPM itself.
This allows newer Fedora distros to avoid pulling in the huge
ceph RPM, in favour of just having the libraries installed
Everything is ready in both netcf and libvirt to switch over to libnl3
in future releases of both Fedora and RHEL. This needs to be done more
or less simultaneously in both packages, though, because you can't mix
libnl1.1 and libnl3 in the same process (e.g. libvirtd using
libnl-3.so and libnetcf.so, while libnetcf.so uses libnl.so)
This patch does two things when fedora >= 18 || rhel >= 7):
1) requires libnl3-devel
2) requires netcf-devel-0.2.2 or greater
(the idea is that a similar patch is going into netcf's specfile, so
that when a build of netcf is done on F18 or later (or RHEL7 or later)
netcf will be guaranteed to be built with libnl3 rather than
libnl-1.1)
* configure.ac, spec file: firewalld defaults to enabled if dbus is
available, otherwise is disabled. If --with_firewalld is explicitly
requested and dbus is not available, configure will fail.
* bridge_driver: add dbus filters to get the FirewallD1.Reloaded
signal and DBus.NameOwnerChanged on org.fedoraproject.FirewallD1.
When these are encountered, reload all the iptables reuls of all
libvirt's virtual networks (similar to what happens when libvirtd is
restarted).
* iptables, ebtables: use firewall-cmd's direct passthrough interface
when available, otherwise use iptables and ebtables commands. This
decision is made once the first time libvirt calls
iptables/ebtables, and that decision is maintained for the life of
libvirtd.
* Note that the nwfilter part of this patch was separated out into
another patch by Stefan in V2, so that needs to be revised and
re-reviewed as well.
================
All the configure.ac and specfile changes are unchanged from Thomas'
V3.
V3 re-ran "firewall-cmd --state" every time a new rule was added,
which was extremely inefficient. V4 uses VIR_ONCE_GLOBAL_INIT to set
up a one-time initialization function.
The VIR_ONCE_GLOBAL_INIT(x) macro references a static function called
vir(Ip|Eb)OnceInit(), which will then be called the first time that
the static function vir(Ip|Eb)TablesInitialize() is called (that
function is defined for you by the macro). This is
thread-safe, so there is no chance of any race.
IMPORTANT NOTE: I've left the VIR_DEBUG messages in these two init
functions (one for iptables, on for ebtables) as VIR_WARN so that I
don't have to turn on all the other debug message just to see
these. Even if this patch doesn't need any other modification, those
messages need to be changed to VIR_DEBUG before pushing.
This one-time initialization works well. However, I've encountered
problems with testing:
1) Whenever I have enabled the firewalld service, *all* attempts to
call firewall-cmd from within libvirtd end with firewall-cmd hanging
internally somewhere. This is *not* the case if firewall-cmd returns
non-0 in response to "firewall-cmd --state" (i.e. *that* command runs
and returns to libvirt successfully.)
2) If I start libvirtd while firewalld is stopped, then start
firewalld later, this triggers libvirtd to reload its iptables rules,
however it also spits out a *ton* of complaints about deletion failing
(I suppose because firewalld has nuked all of libvirt's rules). I
guess we need to suppress those messages (which is a more annoying
problem to fix than you might think, but that's another story).
3) I noticed a few times during this long line of errors that
firewalld made a complaint about "Resource Temporarily
unavailable. Having libvirtd access iptables commands directly at the
same time as firewalld is doing so is apparently problematic.
4) In general, I'm concerned about the "set it once and never change
it" method - if firewalld is disabled at libvirtd startup, causing
libvirtd to always use iptables/ebtables directly, this won't cause
*terrible* problems, but if libvirtd decides to use firewall-cmd and
firewalld is later disabled, libvirtd will not be able to recover.
The 'make check' was rebuilding the binaries just overrided,
so for more safety also override the C program

This patch brings support to manage sheepdog pools and volumes to libvirt.
It uses the "collie" command-line utility that comes with sheepdog for that.
A sheepdog pool in libvirt maps to a sheepdog cluster.
It needs a host and port to connect to, which in most cases
is just going to be the default of localhost on port 7000.
A sheepdog volume in libvirt maps to a sheepdog vdi.
To create one specify the pool, a name and the capacity.
Volumes can also be resized later.
In the volume XML the vdi name has to be put into the <target><path>.
To use the volume as a disk source for virtual machines specify
the vdi name as "name" attribute of the <source>.
The host and port information from the pool are specified inside the host tag.
<disk type='network'>
...
<source protocol="sheepdog" name="vdi_name">
<host name="localhost" port="7000"/>
</source>
</disk>

This patch adds support for a new storage backend with RBD support.
RBD is the RADOS Block Device and is part of the Ceph distributed storage
system.
It comes in two flavours: Qemu-RBD and Kernel RBD, this storage backend only
supports Qemu-RBD, thus limiting the use of this storage driver to Qemu only.
To function this backend relies on librbd and librados being present on the
local system.
The backend also supports Cephx authentication for safe authentication with
the Ceph cluster.
For storing credentials it uses the built-in secret mechanism of libvirt.
