A previous patch used existing #define for the various files in /etc/pki
instead of hardcoding them in the help output. However I missed that
remote_driver.h contains #define for more paths that are present
in the daemon help output.
This commit uses the existing constants for the path to the
configuration file and to the libvirt sockets.
There are constants for these paths in remote_driver.h so we can
use these rather than duplicating them in the help output.

The virtlockd/libvirtd daemons had listed '?' as the short option
for --help. getopt_long uses '?' for any unknown option. We want
to be able to distinguish unknown options (which use EXIT_FAILURE)
from correct usage of help (which should use EXIT_SUCCESS). Thus
we should use 'h' as a short option for --help. Also add this to
the man page docs
The virtlockd/libvirtd daemons did not list any short option
for the --version arg. Add -V as a valid short option, since
-v is already used for --verbose.

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
auto shutdown timeout is reached and the client doesn't have a chance
to connect. To avoid that inhibit daemon shutdown during driver
initialization (which includes capabilities probing).
This fixes

Currently to deal with auto-shutdown libvirtd must periodically
poll all stateful drivers. Thus sucks because it requires
acquiring both the driver lock and locks on every single virtual

which drivers can invoke whenever they want to inhibit shutdown
due to existance of active VMs.

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.

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.

When running libvirtd from a build directory, libvirtd would load lock
drivers from system directory unless explicitly overridden by setting
LIBVIRT_LOCK_MANAGER_PLUGIN_DIR environment variable. Since we already
autodetect driver directory if libvirt is build with driver modules, we
can use the same trick to automagically set lock driver directory.
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.

Use XDG Base Directories instead of storing in home directory
Accidentally changed the umask when creating /var/run/libvirt

The driver modules all use symbols which are defined in libvirt.so.
Thus for loading of modules to work, the binary that libvirt.so
is linked to must export its symbols back to modules. If the
libvirt.so itself is dlopen()d then the RTLD_GLOBAL flag must
be set. Unfortunately few, if any, programming languages use
the RTLD_GLOBAL flag when loading modules :-( This means is it
not practical to use driver modules for any libvirt client side
drivers (OpenVZ, VMWare, Hyper-V, Remote client, test).

No thanks to 64-bit windows, with 64-bit pid_t, we have to avoid
constructs like 'int pid'. Our API in libvirt-qemu cannot be
changed without breaking ABI; but then again, libvirt-qemu can
only be used on systems that support UNIX sockets, which rules
out Windows (even if qemu could be compiled there) - so for all
points on the call chain that interact with this API decision,
we require a different variable name to make it clear that we

Valgrind detected a pipe fd leak before the parent exits on success,
introduced in commit 4296cea; by itself, the leak is not bad, since
we immediately called _exit(), but we might as well be clean to make
valgrind analysis easier. Meanwhile, if the daemon grandchild detects
an error, the parent failed to flush the error message before exiting.
Also, we had the possibility of both parent and child returning to the
caller, such that the user could see duplicated reports of failure
from the two return paths. And we might as well be robust to the

This is a regression introduced by new RPC codes, previously
we advertise the service via ssh even if the daemon doesn't
listen on TLS port (TCP is not choosed). Now the service is
only advertised when it listens on TLS or TCP port. This breaks
upper layer apps which intends to discover the service, such
as virt-manager.
This is a bit painful for example when starting virt-manager
it tends to clutter libvirtd.log with invalid operation on cpu pinning
for defined but not running domains. A priori those kind of errors
don't indicate an error when executing the command but on a precondition
for running the API, and honnestly while the application should report
it, logging it as an error in libvirtd.log is not really useful,

* daemon/libvirtd.c: extend daemonErrorLogFilter() to filter out
errors of type VIR_ERR_OPERATION_INVALID
This patch annotates APIs with low or high priority.
In low set MUST be all APIs which might eventually access monitor
(and thus block indefinitely). Other APIs may be marked as high
priority. However, some must be (e.g. domainDestroy).
For high priority calls (HPC), there are some high priority workers
(HPW) created in the pool. HPW can execute only HPC, although normal
worker can process any call regardless priority. Therefore, only those
APIs which are guaranteed to end in reasonable small amount of time
can be marked as HPC.
The size of this HPC pool is static, because HPC are expected to end
quickly, therefore jobs assigned to this pool will be served quickly.
It can be configured in libvirtd.conf via prio_workers variable.
Default is set to 5.
To mark API with low or high priority, append priority:{low|high} to
it's comment in src/remote/remote_protocol.x. This is similar to
autogen|skipgen. If not marked, the generator assumes low as default.

When spice_tls is set but listen_tls is not, we don't initialize

internal structs and throws an error.
Although, we might now initialize GnuTLS twice, it is safe according
to the documentation:
This function can be called many times,
but will only do something the first time.
This patch creates 2 functions: virNetTLSInit and virNetTLSDeinit

When libvirtd starts it it will sanity check its own certs,

will sanity check their own certs. This patch allows such
sanity checking to be skipped. There is no strong reason to
need to do this, other than to bypass possible libvirt bugs
in sanity checking, or for testing purposes.
libvirt.conf gains tls_no_sanity_certificate parameter to

This guts the libvirtd daemon, removing all its networking and
RPC handling code. Instead it calls out to the new virServerPtr
APIs for all its RPC & networking work
As a fallout all libvirtd daemon error reporting now takes place
via the normal internal error reporting APIs. There is no need
to call separate error reporting APIs in RPC code, nor should
code use VIR_WARN/VIR_ERROR for reporting fatal problems anymore.
* daemon/qemu_dispatch_*.h, daemon/remote_dispatch_*.h: Remove
old generated dispatcher code
* daemon/qemu_dispatch.h, daemon/remote_dispatch.h: New dispatch
code
* daemon/dispatch.c, daemon/dispatch.h: Remove obsoleted code
* daemon/remote.c, daemon/remote.h: Rewrite for new dispatch
APIs
* daemon/libvirtd.c, daemon/libvirtd.h: Remove all networking
code
* daemon/stream.c, daemon/stream.h: Update for new APIs
* daemon/Makefile.am: Link to libvirt-net-rpc-server.la
Since we virEventRegisterDefaultImpl is now a public API, callers need
a way to invoke the default registered Handle and Timeout functions. We
already have general functions for these internally, so promote
them to the public API.
v2:
Actually add APIs to libvirt.h
