Change the build process & driver initialization so that the
VirtualBox driver is built into libvirtd, instead of libvirt.so
This change avoids the VirtualBox GPLv2-only license causing
compatibility problems with libvirt.so which is under the
GPLv2-or-later license.
NB this change prevents use of the VirtualBox driver on the
Windows platform, until such time as libvirtd can be made
to work there.

CVE-2013-1962
remoteDispatchStoragePoolListAllVolumes wasn't freeing the pool.
The pool also held a reference to the connection, preventing it from
getting freed and closing the netcf interface driver, which held two
sockets open.
Automake already passes all CFLAGS to the linker too, so it
is not necessary to set WARN_LDFLAGS in addition to the
WARN_CFLAGS variable.

Currently the virGetHostname() API has a bogus virConnectPtr
parameter. This is because virtualization drivers directly
reference this API in their virDriverPtr tables, tieing its
API design to the public virConnectGetHostname API design.
This also causes problems for access control checks since
these must only be done for invocations from the public
API, not internal invocation.
Remove the bogus virConnectPtr parameter, and make each
hypervisor driver provide a dedicated function for the
driver API impl. This will allow access control checks
to be easily inserted later.

Since PIDs can be reused, polkit prefers to be given
a (PID,start time) pair. If given a PID on its own,
it will attempt to lookup the start time in /proc/pid/stat,
though this is subject to races.
It is safer if the client app resolves the PID start
time itself, because as long as the app has the client
socket open, the client PID won't be reused.

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
Ensure that the driver struct field names match the public

There's a quite old bug entry here:
https://bugzilla.redhat.com/show_bug.cgi?id=700010
I just stumbled over that very issue on F18. Doing a little bit
debugging of the shutdown sequence, it turns out that - at least on my
F18 installation - libvirtd is shutdown *after* iscsid, which makes it
impossible for libvirt to perform the logout of the iscsi session properly.
This patch simply adds another startup dependancy on iscsid.service
which in turn delays iscsid shutdown until after libvirtd has stopped.
Having that applied, the system shuts down properly again.

This patch introduces support for LXC specific public APIs. In
common with what was done for QEMU, this creates a libvirt_lxc.so
library and libvirt/libvirt-lxc.h header file.
The actual APIs are
int virDomainLxcOpenNamespace(virDomainPtr domain,
int **fdlist,
unsigned int flags);
int virDomainLxcEnterNamespace(virDomainPtr domain,
unsigned int nfdlist,
int *fdlist,
unsigned int *noldfdlist,
int **oldfdlist,
unsigned int flags);
which provide a way to use the setns() system call to move the
calling process into the container's namespace. It is not
practical to write in a generically applicable manner. The
nearest that we could get to such an API would be an API which
allows to pass a command + argv to be executed inside a
container. Even if we had such a generic API, this LXC specific
API is still useful, because it allows the caller to maintain
the current process context, in particular any I/O streams they
have open.
NB the virDomainLxcEnterNamespace() API is special in that it
runs client side, so does not involve the internal driver API.

I did a build --without-libvirtd, then ran 'make dist'. The
resulting tarball was broken, with a complaint that make did not

https://bugzilla.redhat.com/show_bug.cgi?id=887017 reports that
even though libvirt attempts to set fs.aio-max-nr via sysctl,
the file was installed with the wrong name and gets ignored by
sysctl. Furthermore, 'man systcl.d' recommends that packages
install into hard-coded /usr/lib/sysctl.d (even when libdir is
/usr/lib64), so that sysadmins can use /etc/sysctl.d for overrides.

As of 1a50ba2cb0 qemu capabilities probing
takes longer since we timeout waiting for the monitor socket. When
probing qemu for different architectures this can add up so the daemon

tried to do the same, but we depended on dbus.target (which
does not exist) in comparison to network.target (which does
exist), so we removed that in commit 4c7973e. But we still
need dbus up and running first, especially now that we want
to support shutdown inhibition via dbus (whereas we originally
needed dbus only for firewall control).

due to existance of active VMs.

This will simplify the refactoring of the ESX storage driver to support
a VMFS and an iSCSI backend.
One of the tasks the storage driver needs to do is to decide which backend
driver needs to be invoked for a given request. This approach extends
virStoragePool and virStorageVol to store extra parameters:
1. privateData: stores pointer to respective backend storage driver.
2. privateDataFreeFunc: stores cleanup function pointer.
virGetStoragePool and virGetStorageVol are modfied to accept these extra
parameters as user params. virStoragePoolDispose and virStorageVolDispose
checks for cleanup operation if available.
The private data pointer allows the ESX storage driver to store a pointer
to the used backend with each storage pool and volume. This avoids the need
to detect the correct backend in each storage driver function call.
The libvirt coding standard is to use 'function(...args...)'
instead of 'function (...args...)'. A non-trivial number of
places did not follow this rule and are fixed in this patch.

It turns out that calling virNodeGetCPUMap(conn, NULL, NULL, 0)

optimize. Since this interface hasn't been released yet, we

A bit more background on the optimization - learning the cpu count
is a single file read (/sys/devices/system/cpu/possible), but
learning the number of online cpus can possibly trigger a file
read per cpu, depending on the age of the kernel, and all wasted

Automatically enable systemd journal logging
Probe to see if the systemd journal is accessible, and if
so enable logging to the journal by default, rather than
stderr (current default under systemd).
Previously 'LIBVIRT_DEBUG=1 /usr/sbin/libvirtd' would show all debug
output to stderr, now it send debug output to the journal.
Only use the journal by default if running in daemon mode, or
if stdin is _not_ a tty. This should make libvirtd launched from
systemd use the journal, but preserve the old behavior in most
situations.

On F17 at least, every time libvirtd starts we get this in syslog:

This comes from cyrus-sasl, and happens regardless of whether the
gssapi plugin is requested, which is what actually uses

Recent work to improve support for loadable driver modules introduced
a regression in the xen driver. The legacy xen driver is now a
stateful, libvirtd driver but was not being registered when building
without driver modules.
A slight behavior change was also noted in the xen drivers when
built as driver modules. Previously, explicitly specifying a
connection URI was not necessary, but now
Compiled against library: libvirt 0.10.0
Using library: libvirt 0.10.0
Using API: QEMU 0.10.0
error: failed to get the hypervisor version
error: internal error Cannot find suitable emulator for x86_64
The xen drivers need to be registered before the qemu driver since
the qemu driver will return success with a null connection URI.
This ordering is safe since the xen drivers will decline when not
running the xen kernel.

Updated the paths in the man page to reflect what the code in libvirtd
does. In addition broke out the FILES section into two subsections for
files used when run as root and files used when run as non-root.
Provided information about the defaults that libvirtd uses when running
as non-root and when XDG_CONFIG_HOME and XDG_RUNTIME_DIR are not set in
the environment.
REMOTE_PID_FILE is no longer used in the source or the build process but
the man page still used it resulting in no file name being displayed.
The same value that the libvirtd daemon code uses is now used in the man
page.
Currently the man page has paths that start with @sysconfdir@,
@localstatedir@ and @remote_pid_file@. The sed command attempts to
replace these during the build but unfortunately pod2man gets to the
files first and escapes the @ character resulting in the sed not
working. This removes the @ character and makes the paths correct.
Currently there is a hook function that is invoked when a
new client connection comes in, which allows an app to
setup private data. This setup will make it difficult to
serialize client state during process re-exec(). Change to
a model where the app registers a callback when creating
the virNetServerPtr instance, which is used to allocate
the client private data immediately during virNetClientPtr
construction.
