I am getting this failure with 'make distcheck':

make[4]: *** [../../src/remote_protocol-structs] Error 1
since it attempts a sub-run of a VPATH 'make check' where $(srcdir)
is intentionally read-only. I'm not sure which commit introduced
the problem, although I suspect it was around 62dee6f when I
refactored protocol struct checking to be more powerful.
$(@F) is required by POSIX, and although it is not yet portable
to all make implementations, we already require GNU make.
* src/Makefile.am (PDWTAGS): Generate temp file into current
directory, since $(srcdir) is read-only during distcheck.
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
When libvirt calls virInitialize it creates a thread local
for the virErrorPtr storage, and registers a callback to
cleanup memory when a thread exits. When libvirt is dlclose()d
or otherwise made non-resident, the callback function is
removed from memory, but the thread local may still exist
and if a thread later exists, it will invoke the callback
and SEGV. There may also be other thread locals with callbacks
pointing to libvirt code, so it is in general never safe to
unload libvirt.so from memory once initialized.
To allow dlclose() to succeed, but keep libvirt.so resident
in memory, link with '-z nodelete'. This issue was first
found with the libvirt CIM provider, but can potentially
hit many of the dynamic language bindings which all ultimately
involve dlopen() in some way, either on libvirt.so itself,
or on the glue code for the binding which in turns links
to libvirt
* configure.ac, src/Makefile.am: Ensure libvirt.so is linked
with -z nodelete
* cfg.mk, .gitignore, tests/Makefile.am, tests/shunloadhelper.c,
tests/shunloadtest.c: A test case to unload libvirt while
a thread is still running.
This patch adds the ability to make the filesystem for a filesystem
pool during a pool build.
The patch adds two new flags, no overwrite and overwrite, to control
when mkfs gets executed. By default, the patch preserves the
current behavior, i.e., if no flags are specified, pool build on a
filesystem pool only makes the directory on which the filesystem
will be mounted.
If the no overwrite flag is specified, the target device is checked
to determine if a filesystem of the type specified in the pool is
present. If a filesystem of that type is already present, mkfs is
not executed and the build call returns an error. Otherwise, mkfs
is executed and any data present on the device is overwritten.
If the overwrite flag is specified, mkfs is always executed, and any
existing data on the target device is overwritten unconditionally.
Domain listing, basic information retrieval and domain life cycle
management is implemented. But currently the domain XML output
lacks the complete devices section.
The driver uses OpenWSMAN to directly communicate with a Hyper-V
server over its WS-Management interface exposed via Microsoft WinRM.
The driver is based on the work of Michael Sievers. This started in
the same master program project group at the University of Paderborn
as the ESX driver.
See Michael's blog for details: http://hyperv4libvirt.wordpress.com/
Add a generator script to generate the structs and serialization
information for OpenWSMAN.
openwsman.h collects workarounds for problems in OpenWSMAN <= 2.2.6.
There are also disabled sections that would use ws_serializer_free_mem
but can't because it's broken in OpenWSMAN <= 2.2.6. Patches to fix
this have been posted upstream.
This patch moves some of the sriov related pci code from node_device driver

The functions for manipulating pidfiles are in util/util.{c,h}.
We will shortly be adding some further pidfile related functions.
To avoid further growing util.c, this moves the pidfile related
functions into a dedicated virpidfile.{c,h}. The functions are
also all renamed to have 'virPidFile' as their name prefix
* util/util.h, util/util.c: Remove all pidfile code

Gettext annoyingly modifies CPPFLAGS in-place, putting
-I/usr/local/include into the search patch if libintl headers
must be used from that location. But since we must support
automake 1.9.6 which lacks AM_CPPFLAGS, and since CPPFLAGS is used
prior to INCLUDES, this means that the build picks up the _old_
installed libvirt.h in priority to the in-tree version, leading
to all sorts of weird build failures on FreeBSD.
Fix this by teaching configure to undo gettext's actions, but
to keep any changes required by gettext at the end of INCLUDES
after all in-tree locations are used first. Also requires
adding a wrapper Makefile.am and making gnulib-tool create
just gnulib.mk files during the bootstrap process.

I went with the shorter license notice used by src/libvirt.c,

Also prepend $(AM_V_GEN) to the command line, mark virkeycode-mapgen.py
as executable and switch the shebang line from /bin/python to the
commonly use /usr/bin/python.
The only 'void name(void)' style procedure in the protocol is 'close' that
is handled special, but also programming errors like a missing _args or
_ret suffix on the structs in the .x files can create such a situation by
accident. Making the generator aware of this avoids bogus errors from the
generator such as:
Use of uninitialized value in exists at ./rpc/gendispatch.pl line 967.
Also this allows to get rid of the -c option and the special case code for
the 'close' procedure, as the generator handles it now correctly.

The current API build scripts will continue and exit with a zero
status even if they find problems. This has been the cause of many
build problems, or hidden build errors, in the past. Change the

they do not understand. Also turn off all debug output by default
so they respect $(AM_V_GEN)
* docs/Makefile.am: Use $(AM_V_GEN) for API/HTML scripts

According to the automake manual, CPPFLAGS (aka INCLUDES, as spelled
in automake 1.9.6) should only include -I, -D, and -U directives; more

To facilitate creation of new clients using XDR RPC services,
pull alot of the remote driver code into a set of reusable
objects.
- virNetClient: Encapsulates a socket connection to a
remote RPC server. Handles all the network I/O for
reading/writing RPC messages. Delegates RPC encoding
and decoding to the registered programs
- virNetClientProgram: Handles processing and dispatch
of RPC messages for a single RPC (program,version).
A program can register to receive async events
from a client
- virNetClientStream: Handles generic I/O stream
integration to RPC layer
Each new client program now merely needs to define the list of
RPC procedures & events it wants and their handlers. It does
not need to deal with any of the network I/O functionality at
all.
Allow RPC servers to advertise themselves using MDNS,
via Avahi
* src/rpc/virnetserver.c, src/rpc/virnetserver.h: Allow

To facilitate creation of new daemons providing XDR RPC services,
pull a lot of the libvirtd daemon code into a set of reusable
objects.
* virNetServer: A server contains one or more services which
accept incoming clients. It maintains the list of active
clients. It has a list of RPC programs which can be used
by clients. When clients produce a complete RPC message,
the server passes this onto the corresponding program for
handling, and queues any response back with the client.
* virNetServerClient: Encapsulates a single client connection.
All I/O for the client is handled, reading & writing RPC
messages.
* virNetServerProgram: Handles processing and dispatch of
RPC method calls for a single RPC (program,version).
Multiple programs can be registered with the server.
* virNetServerService: Encapsulates socket(s) listening for
new connections. Each service listens on a single host/port,
but may have multiple sockets if on a dual IPv4/6 host.
Each new daemon now merely has to define the list of RPC procedures
& their handlers. It does not need to deal with any network related
functionality at all.
This provides two modules for handling SASL
* virNetSASLContext provides the process-wide state, currently
just a whitelist of usernames on the server and a one time
library init call
* virNetTLSSession provides the per-connection state, ie the
SASL session itself. This also include APIs for providing
data encryption/decryption once the session is established
* src/Makefile.am: Add to libvirt-net-rpc.la
* src/rpc/virnetsaslcontext.c, src/rpc/virnetsaslcontext.h: Generic

* virNetTLSContext provides the process-wide state, in particular
all the x509 credentials, DH params and x509 whitelists
* virNetTLSSession provides the per-connection state, ie the
TLS session itself.
The virNetTLSContext provides APIs for validating a TLS session's
x509 credentials. The virNetTLSSession includes APIs for performing

This provides a new struct that contains a buffer for the RPC
message header+payload, as well as a decoded copy of the message
header. There is an API for applying a XDR encoding & decoding
of the message headers and payloads. There are also APIs for
maintaining a simple FIFO queue of message instances.
Expected usage scenarios are:
To send a message
msg = virNetMessageNew()
...fill in msg->header fields..
virNetMessageEncodeHeader(msg)
...loook at msg->header fields to determine payload filter
virNetMessageEncodePayload(msg, xdrfilter, data)
...send msg->bufferLength worth of data from buffer
To receive a message
msg = virNetMessageNew()
...read VIR_NET_MESSAGE_LEN_MAX of data into buffer
virNetMessageDecodeLength(msg)
...read msg->bufferLength-msg->bufferOffset of data into buffer
virNetMessageDecodeHeader(msg)
...look at msg->header fields to determine payload filter
virNetMessageDecodePayload(msg, xdrfilter, data)
...run payload processor

This patch defines the basics of a generic RPC protocol in XDR.
This is wire ABI compatible with the original remote_protocol.x.
It takes everything except for the RPC calls / events from that
protocol
- The basic header virNetMessageHeader (aka remote_message_header)
- The error object virNetMessageError (aka remote_error)
- Two dummy objects virNetMessageDomain & virNetMessageNetwork
sadly needed to keep virNetMessageError ABI compatible with
the old remote_error
The RPC protocol supports method calls, async events and
bidirectional data streams as before
* src/Makefile.am: Add rules for generating RPC code from
protocol & define a new libvirt-net-rpc.la helper library
* src/rpc/virnetprotocol.x: New generic RPC protocol

In preparation for removing generated files, it is necessary
to tell automake that the generated files must be distributed

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.

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

The introduction of the v3 migration protocol, along with
support for migration cookies, will significantly expand
the size of the migration code. Move it all to a separate
file to make it more manageable
The functions are not moved 100%. The API entry points
remain in the main QEMU driver, but once the public
virDomainPtr is resolved to the internal virDomainObjPtr,
all following code is moved.
This will allow the new v3 API entry points to call into the
same shared internal migration functions
* src/qemu/qemu_domain.c, src/qemu/qemu_domain.h: Add
qemuDomainFormatXML helper method
* src/qemu/qemu_driver.c: Remove all migration code

Move the qemudStartVMDaemon and qemudShutdownVMDaemon
methods into a separate file, renaming them to
qemuProcessStart, qemuProcessStop. All helper methods
called by these are also moved & renamed to match

Error: Expecting a partition number.
This patch introduces 'dmsetup' to fix it.
Changes:
- New function "virIsDevMapperDevice" in "src/utils/utils.c"
- remove "is_dm_device" in "src/storage/parthelper.c", use
"virIsDevMapperDevice" instead.
- Requires "device-mapper" for 'with-storage-disk" in "libvirt.spec.in"
- Check "dmsetup" in 'configure.ac' for "with-storage-disk"
- Changes on "src/Makefile.am" to link against libdevmapper
- New entry for "virIsDevMapperDevice" in "src/libvirt_private.syms"
Changes from v1 to v3:
- s/virIsDeviceMapperDevice/virIsDevMapperDevice/g
- replace "virRun" with "virCommand"
- sort the list of util functions in "libvirt_private.syms"
- ATTRIBUTE_NONNULL(1) for virIsDevMapperDevice declaration.

When built as modules, the connection drivers live
in $LIBDIR/libvirt/drivers. Now we add lock manager
drivers, we need to distinguish. So move the existing
modules to 'connection-driver'
* src/Makefile.am: Move module install dir
* src/driver.c: Move module search dir
The current security driver usage requires horrible code like
if (driver->securityDriver &&
driver->securityDriver->domainSetSecurityHostdevLabel &&
driver->securityDriver->domainSetSecurityHostdevLabel(driver->securityDriver,
vm, hostdev) < 0)
This pair of checks for NULL clutters up the code, making the driver
calls 2 lines longer than they really need to be. The goal of the
patchset is to change the calling convention to simply
if (virSecurityManagerSetHostdevLabel(driver->securityDriver,
vm, hostdev) < 0)
The first check for 'driver->securityDriver' being NULL is removed
by introducing a 'no op' security driver that will always be present
if no real driver is enabled. This guarentees driver->securityDriver
!= NULL.
The second check for 'driver->securityDriver->domainSetSecurityHostdevLabel'
being non-NULL is hidden in a new abstraction called virSecurityManager.
This separates the driver callbacks, from main internal API. The addition
of a virSecurityManager object, that is separate from the virSecurityDriver
struct also allows for security drivers to carry state / configuration
information directly. Thus the DAC/Stack drivers from src/qemu which
used to pull config from 'struct qemud_driver' can now be moved into
the 'src/security' directory and store their config directly.
* src/qemu/qemu_conf.h, src/qemu/qemu_driver.c: Update to
use new virSecurityManager APIs
* src/qemu/qemu_security_dac.c, src/qemu/qemu_security_dac.h

Update to take virSecurityManagerPtr object as the first param
in all callbacks
* src/security/security_nop.c, src/security/security_nop.h: Stub
implementation of all security driver APIs.
* src/security/security_manager.h, src/security/security_manager.c:
New internal API for invoking security drivers
* src/libvirt.c: Add missing debug for security APIs
Add vboxArrayGetWithUintArg to handle new signature variations. Also
refactor vboxArrayGet* implementation to use a common helper function.
Deal with the incompatible changes in the VirtualBox 4.0 API. This
includes major changes in virtual machine and storage medium lookup,
in RDP server property handling, in session/lock handling and other
minor areas.
VirtualBox 4.0 also dropped the old event API and replaced it with a
completely new one. This is not fixed yet and will be addressed in
another patch. Therefore, currently the domain events are supported
for VirtualBox 3.x only.
Based on initial work from Jean-Baptiste Rouault.
This fixes the build from a tarball and makes autobuild.sh
work again.
This should actually have been part of this earlier commit:
esx: Move VMX handling code out of the driver directory
42b2f35d36
Reported by Eric Blake.
All other drivers are explicitly linked to gnulib. The VMware
driver lacked this, resulting in mdir_name being an undefine
symbol.
Explicitly link the VMware driver to gnulib to fix this.
Now the VMware driver doesn't depend on the ESX driver anymore.
Add a WITH_VMX option that depends on WITH_ESX and WITH_VMWARE.
Also add a libvirt_vmx.syms file.
Move some escaping functions from esx_util.c to vmx.c.
Adapt the test suite, ESX and VMware driver to the new code layout.
* configure.ac (dlopen): Cygwin dlopen is in libc; avoid spurious
failure.
(XDR_CFLAGS): Define when needed.
* src/Makefile.am (libvirt_driver_remote_la_CFLAGS): Use it.
Don't require dlopen, but link to ole32 and oleaut32 on Windows.
Don't expose g_pVBoxFuncs anymore. It was only used to get the
version of the API. Make VBoxCGlueInit return the version instead.
This simplifies the implementation of the MSCOM glue layer.
Get the VirtualBox version from the registry.
Add a dummy implementation of the nsIEventQueue to the MSCOM glue
as there seems to be no direct equivalent with MSCOM. It might be
implemented using the normal window message loop. This requires
additional investigation.
The QEMU driver file is far too large. Move all the hotplug

This introduces a new set of APIs in src/util/command.h
to use for invoking commands. This is intended to replace
all current usage of virRun and virExec variants, with a
more flexible and less error prone API.

To avoid the need for duplicating implementations of virStream
drivers, provide a generic implementation that can handle any
FD based stream. This code is copied from the existing impl
in the QEMU driver, with the locking moved into the stream
impl, and addition of a read callback
The FD stream code will refuse to operate on regular files or
block devices, since those can't report EAGAIN properly when
they would block on I/O
* include/libvirt/virterror.h, include/libvirt/virterror.h: Add
VIR_FROM_STREAM error domain
* src/qemu/qemu_driver.c: Remove code obsoleted by the new
generic streams driver.
* src/fdstream.h, src/fdstream.c, src/fdstream.c,
src/libvirt_private.syms: Generic reusable FD based streams
