This function aims at converting LXC configuration into a libvirt

Here is an example of how the lxc configuration works:

It is possible that some parts couldn't be properly mapped into a

before creating the domain.
fstab files in lxc.mount lines will need to be merged into the

default value for max_balloon that users will probably want to adjust.

This test is there to ensure that our capabilities detection code isn't
broken somehow.
How to gather test data:
Firstly, the data is split into two separate files. The former (with
suffix .replies) contains all the qemu replies. This is very fragile as
introducing a new device can mean yet another monitor command and hence
edit of this file in the future. But there's no better way of doing
this. To get this data simply turn on debug logs and copy all the
QEMU_MONITOR_IO_PROCESS lines. But be careful to not copy incomplete
ones (yeah, we report some incomplete lines too). Long story short, at
the libvirtd startup, a dummy qemu is spawn to get all the capabilities.
The latter (with suffix .caps) contains capabilities XML. Just start a
domain and copy the corresponding part from its state XML file.

<check object='connect' perm='search_domains'/>
<filter object='domain' perm='getattr'/>
</api>
<api name='virDomainAttachDeviceFlags'>
<check object='domain' perm='write'/>
<check object='domain' perm='save' flags='!VIR_DOMAIN_AFFECT_CONFIG|VIR_DOMAIN_AFFECT_LIVE'/>
<check object='domain' perm='save' flags='VIR_DOMAIN_AFFECT_CONFIG'/>

To register virtual machines and containers with systemd-machined,

This is somewhat tedious code, so introduce a dedicated function
to isolate the DBus call in one place.
Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
Doing DBus method calls using libdbus.so is tedious in the
extreme. systemd developers came up with a nice high level
API for DBus method calls (sd_bus_call_method). While
systemd doesn't use libdbus.so, their API design can easily
be ported to libdbus.so.
This patch thus introduces methods virDBusCallMethod &
virDBusMessageRead, which are based on the code used for
sd_bus_call_method and sd_bus_message_read. This code in
systemd is under the LGPLv2+, so we're license compatible.
This code is probably pretty unintelligible unless you are
familiar with the DBus type system. So I added some API
docs trying to explain how to use them, as well as test
cases to validate that I didn't screw up the adaptation
from the original systemd code.

As my punishment for the break in 7f15ebc7 (fixed in 752596b5dd) I'm
introducing this test to make sure it won't happen again. Currently,
only test for <graphics/> is supported.
Extend the 'gendispatch.pl' script to be able to generate
three new types of file.
- 'aclheader' - defines signatures of helper APIs for
doing authorization checks. There is one helper API
for each API requiring an auth check. Any @acl
annotations result in a method being generated with
a suffix of 'EnsureACL'. If the ACL check requires
examination of flags, an extra 'flags' param will be
present. Some examples
extern int virConnectBaselineCPUEnsureACL(void);
extern int virConnectDomainEventDeregisterEnsureACL(virDomainDefPtr domain);
extern int virDomainAttachDeviceFlagsEnsureACL(virDomainDefPtr domain, unsigned int flags);
Any @aclfilter annotations resuilt in a method being
generated with a suffix of 'CheckACL'.
extern int virConnectListAllDomainsCheckACL(virDomainDefPtr domain);
These are used for filtering individual objects from APIs
which return a list of objects
- 'aclbody' - defines the actual implementation of the
methods described above. This calls into the access
manager APIs. A complex example:
/* Returns: -1 on error (denied==error), 0 on allowed */
int virDomainAttachDeviceFlagsEnsureACL(virConnectPtr conn,
virDomainDefPtr domain,
unsigned int flags)
{
virAccessManagerPtr mgr;
int rv;
if (!(mgr = virAccessManagerGetDefault()))
return -1;
if ((rv = virAccessManagerCheckDomain(mgr,
conn->driver->name,
domain,
VIR_ACCESS_PERM_DOMAIN_WRITE)) <= 0) {
virObjectUnref(mgr);
if (rv == 0)
virReportError(VIR_ERR_ACCESS_DENIED, NULL);
return -1;
}
if (((flags & (VIR_DOMAIN_AFFECT_CONFIG|VIR_DOMAIN_AFFECT_LIVE)) == 0) &&
(rv = virAccessManagerCheckDomain(mgr,
conn->driver->name,
domain,
VIR_ACCESS_PERM_DOMAIN_SAVE)) <= 0) {
virObjectUnref(mgr);
if (rv == 0)
virReportError(VIR_ERR_ACCESS_DENIED, NULL);
return -1;
}
if (((flags & (VIR_DOMAIN_AFFECT_CONFIG)) == (VIR_DOMAIN_AFFECT_CONFIG)) &&
(rv = virAccessManagerCheckDomain(mgr,
conn->driver->name,
domain,
VIR_ACCESS_PERM_DOMAIN_SAVE)) <= 0) {
virObjectUnref(mgr);
if (rv == 0)
virReportError(VIR_ERR_ACCESS_DENIED, NULL);
return -1;
}
virObjectUnref(mgr);
return 0;
}
- 'aclsyms' - generates a linker script to export the
APIs to drivers. Some examples
virConnectBaselineCPUEnsureACL;
virConnectCompareCPUEnsureACL;

Some aspects of the cgroups setup / detection code are quite subtle
and easy to break. It would greatly benefit from unit testing, but
this is difficult because the test suite won't have privileges to
play around with cgroups. The solution is to use monkey patching
via LD_PRELOAD to override the fopen, open, mkdir, access functions
to redirect access of cgroups files to some magic stubs in the
test suite.
Using this we provide custom content for the /proc/cgroup and
/proc/self/mounts files which report a fixed cgroup setup. We
then override open/mkdir/access so that access to the cgroups
filesystem gets redirected into files in a temporary directory
tree in the test suite build dir.

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 'git add .', then realized that it ended up trying to
add the emacs lock file for a corresponding file that I had not

we already exclude other temporary files, this makes the most
sense for preventing such a mistake from actually hitting upstream.
* .gitignore: Add .#* to the exclude list.

The previously introduced virFile{Lock,Unlock} APIs provide a
way to acquire/release fcntl() locks on individual files. For
unknown reason though, the POSIX spec says that fcntl() locks
are released when *any* file handle referring to the same path
is closed. In the following sequence
threadA: fd1 = open("foo")
threadB: fd2 = open("foo")
threadA: virFileLock(fd1)
threadB: virFileLock(fd2)
threadB: close(fd2)
you'd expect threadA to come out holding a lock on 'foo', and
indeed it does hold a lock for a very short time. Unfortunately
when threadB does close(fd2) this releases the lock associated
with fd1. For the current libvirt use case for virFileLock -
pidfiles - this doesn't matter since the lock is acquired
at startup while single threaded an never released until
exit.
To provide a more generally useful API though, it is necessary
to introduce a slightly higher level abstraction, which is to
be referred to as a "lockspace". This is to be provided by
a virLockSpacePtr object in src/util/virlockspace.{c,h}. The
core idea is that the lockspace keeps track of what files are
already open+locked. This means that when a 2nd thread comes
along and tries to acquire a lock, it doesn't end up opening
and closing a new FD. The lockspace just checks the current
list of held locks and immediately returns VIR_ERR_RESOURCE_BUSY.
NB, the API as it stands is designed on the basis that the
files being locked are not being otherwise opened and used
by the application code. One approach to using this API is to
acquire locks based on a hash of the filepath.
eg to lock /var/lib/libvirt/images/foo.img the application
might do
virLockSpacePtr lockspace = virLockSpaceNew("/var/lib/libvirt/imagelocks");
lockname = md5sum("/var/lib/libvirt/images/foo.img");
virLockSpaceAcquireLock(lockspace, lockname);
NB, in this example, the caller should ensure that the path
is canonicalized before calculating the checksum.
It is also possible to do locks directly on resources by
using a NULL lockspace directory and then using the file
path as the lock name eg
virLockSpacePtr lockspace = virLockSpaceNew(NULL);
virLockSpaceAcquireLock(lockspace, "/var/lib/libvirt/images/foo.img");
This is only safe to do though if no other part of the process
will be opening the files. This will be the case when this
code is used inside the soon-to-be-reposted virlockd daemon

There are a few issues with the current virAtomic APIs
- They require use of a virAtomicInt struct instead of a plain

- Several of the methods do not implement memory barriers
- The methods do not implement compiler re-ordering barriers
- There is no Win32 native impl
The GLib library has a nice LGPLv2+ licensed impl of atomic
ops that works with GCC, Win32, or pthreads.h that addresses
all these problems. The main downside to their code is that
the pthreads impl uses a single global mutex, instead of

single RPC message defined thus far, an asynchronous "EXIT"
event that is emitted just before the LXC controller process
exits. This provides the LXC driver with details about how
the container shutdown - normally, or abnormally (crashed),
thus allowing the driver to emit better libvirt events.
Emitting the event in the LXC controller requires a few
little tricks with the RPC service. Simply calling the
virNetServiceClientSendMessage does not work, since this
merely queues the message for asynchronous processing.
In addition the main event loop is no longer running at
the point the event is emitted, so no I/O is processed.
Thus after invoking virNetServiceClientSendMessage it is
necessary to mark the client as being in "delayed close"
mode. Then the event loop is run again, until the client
completes its close - this happens only after the queued
message has been fully transmitted. The final complexity
is that it is not safe to run virNetServerQuit() from the
client close callback, since that is invoked from a
context where the server is locked. Thus a zero-second
timer is used to trigger shutdown of the event loop,
causing the controller to finally exit.
* src/Makefile.am: Add rules for generating RPC protocol
files and dispatch methods
* src/lxc/lxc_controller.c: Emit an RPC event immediately
before exiting
* src/lxc/lxc_domain.h: Record the shutdown reason

If from a clean GIT checkout 'make -j 8' is run, the ESX
and Hyper-V code will be generated multiple times over.
This is because there are multiple files being generated
from one invocation of the generator script. make does not
realize this and so invokes the generator once per file.
This doesn't matter with serialized builds, but with
parallel builds multiple instances of the generator get
run at once.

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>
To work right this patch parses the output of collie,
so it relies on the raw output option. There recently was a bug which caused
size information to be reported wrong. This is fixed upstream already and
will be in the next release.

The Mingw32 toolchain is broadly obsoleted by the Mingw64 toolchain.
The latter has been adopted by Fedora 17 and newer. Maintaining a
RPM spec for Mingw32 is a needless burden, so switch to a Mingw64

Without this fix, a VPATH build (such as used by ./autobuild.sh)

Since the test files are not part of the tarball, we can generate

libvirt.git/src.

When adding new config file parameters, the corresponding

Also there are augeas test cases, these don't catch the

The daemon-conf test script continues to be very fragile to
changes in libvirt. It currently fails 1 time in 3/4 due
to race conditions in startup/shutdown of the test script.
Replace it with a proper test case tailored to the code
being tested
* tests/Makefile.am: Remove daemon-conf, add libvirtdconftest
* tests/daemon-conf: Delete obsolete test
* tests/libvirtdconftest.c: Test config file handling
Otherwise, 'make check' breaks since commit bc1ff160 deleted
qparams.h. A later patch will ensure that viruri takes over
what qparams used to do.
* tests/qparamtest.c (mymain): Delete, now that we have viruri.
* tests/Makefile.am (check_PROGRAMS, TESTS, qparamtest_SOURCES):
Delete old test.
* .gitignore: Add recent test additions.
The file daemon/probes.h used to be generated as part of a build, but
is no longer used. However, a stale copy of it lying around could
cause a build to fail. Removing it from .gitignore will make it more
likely someone will notice that they have it lying around.
QMP commands don't need to be escaped since converting them to json
also escapes special characters. When a QMP command fails, however,
libvirt falls back to HMP commands. These fallback functions
(qemuMonitorText*) do their own escaping, and pass the result directly
to qemuMonitorHMPCommandWithFd. If the monitor is in json mode, these
pre-escaped commands will be escaped again when converted to json,
which can result in the wrong arguments being sent.
For example, a filename test\file would be sent in json as
test\\file.
This prevented attaching an image file with a " or \ in its name in
qemu 1.0.50, and also broke rbd attachment (which uses backslashes to
escape some internal arguments.)

The keepalive program has two procedures: PING, and PONG.
Both are used only in asynchronous messages and the sender doesn't wait
for any reply. However, the party which receives PING messages is
supposed to react by sending PONG message the other party, but no
explicit binding between PING and PONG messages is made. For backward
compatibility neither server nor client are allowed to send keepalive
messages before checking that remote party supports them.

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

this have been posted upstream.
I did 'git add .' while in the middle of 'make syntax-check', and
it picked up a temporary file that should not be committed.
* .gitignore: Ignore sc_* from syntax check.
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.

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.

This patch defines the basics of a generic RPC protocol in XDR.
This is wire ABI compatible with the original remote_protocol.x.

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

Setting this to /dev/null avoids an otherwise harmless diagnostic.
This makes it so we record (via a git submodule)
a snapshot of whatever version of gnulib we're using,
and none of gnulib sources are in the libvirt repository.
The result is that we have as much reproducibility as when
we version-controlled imported copies of the gnulib sources,
but without the hassle of the manual process we used when
syncing with upstream.
Note that when you clone libvirt, you get only the libvirt
repository, but when you first run ./bootstrap, it clones
gnulib (at the SHA1 recorded via the submodule), creating
the .gnulib/ hierarchy. Then, the bootstrap script runs
gnulib-tool to populate gnulib/ with the files that make
up the selected modules.
