Having a daemon/ directory makes little sense from a code structure
point of view, as 90% of the code that is built into libvirtd already
lives in the src/ directory. The virtlockd and virlogd daemons also live
entirely in src/{locking,logging} directories. This moves the source
code for libvirtd into src/remote/, alongside the client code.

A long time ago we imported the keymaps.csv file from GTK-VNC so we
can do conversions between keycode sets. Meanwhile lots of bug fixes
have gone into this CSV file and libvirt hasn't kept in sync. The
keymaps.csv file and associated generator script has been pulled out
of GTK-VNC into a dedicated GIT repo for use as a submodule. This
allows GTK-VNC, SPICE-GTK, QEMU and libvirt to share the same master
database and tools and pushing updates merely requires a submodule
commit update as with gnulib.
The test suite is updated to cover some extra boundary conditions.

Currently, building the NEWS file involves using a XSLT stylesheet
to extract information from the same HTML file that's used on the
libvirt website.
The process works, but it's quite fiddly in that it requires the
source HTML to be formatted in a very precise way, and a single
missing newline can mess up the resulting plain text considerably.
Moreover, the XSLT stylesheet itself encodes a lot of the details
of converting to plain text in a way that's not necessarily easy
to understand, tweak or fix.
To improve the process, move all existing entries to a new XML
file that contains exactly the information we care about in a
simple structured format, and start generating both the HTML and
plain text versions of the release notes using XSLT stylesheets
that can now afford to be almost trivial.
Just like we are running 'virsh self-test' from within our test

A new hidden command for virsh that will iterate over

This involves running vshCmddefOptParse so we can get an error if

This allows us to produce releases that are roughly a third in
size, have no limitation on path length, and are still readable
by all supported platforms.
All the accesses to files outside our build or source directories
are now identified and appended into a file for later processing.
The location of the file that contains all the records can be

We shouldn't advertise libvirtd.socket activation, since currently

We tried to find a middle ground by installing the config file without

without one... or at least it did do that; presently on f24 it allows
activating the socket quite happily. This also caused user confusion[1]

This patch introduces virt-admin client which is based on virsh client,
but had to reimplement several methods to meet virt-admin specific needs
or remove unnecessary virsh specific logic.
As it turned out, we need to share some enums and declarations between
libvirt.h and libvirt-admin.h, but since our policy forbids direct includes of
libvirt*.h, there has to be some header exempt from this rule. This patch moves
the relevant part of code from libvirt.h.in to libvirt-common.h.in. Moreover,
since there is no need to have libvirt.h generated anymore, introduce a new
header libvirt.h which was previosly ignored from git and make the common
header ignored and generated instead.
Copy the virtlockd codebase across to form the initial virlogd
code. Simple search & replace of s/lock/log/ and gut the remote

and listens for connections, but does nothing with them.

Introduce a Xen xl parser
This parser allows for users to convert the new xl disk format and
spice graphics config to libvirt xml format and vice versa. Regarding
the spice graphics config, the code is pretty much straight forward.
For the disk {formating, parsing}, this parser takes care of the new
xl format which include positional parameters and key/value parameters.
In xl format disk config a <diskspec> consists of parameters separated by
commas. If the parameters do not contain an '=' they are automatically
assigned to certain options following the order below
target, format, vdev, access
The above are the only mandatory parameters in the <diskspec> but there
are many more disk config options. These options can be specified as
key=value pairs. This takes care of the rest of the options such as
devtype, backend, backendtype, script, direct-io-safe,
The positional paramters can also be specified in key/value form
for example
/dev/vg/guest-volume,,hda
/dev/vg/guest-volume,raw,hda,rw
format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume
are interpleted to one config.
In xm format, the above diskspec would be written as
phy:/dev/vg/guest-volume,hda,w
The disk parser is based on the same parser used successfully by
the Xen project for several years now. Ian Jackson authored the
scanner, which is used by this commit with mimimal changes. Only
the PREFIX option is changed, to produce function and file names
more consistent with libvirt's convention.

It would be nice if we have an example to inspire people. And that's

I've chosen this one as I think it show explicitly what users need to

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.

Doing DBus method calls using libdbus.so is tedious in the

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

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) {

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,

virObjectUnref(mgr);
if (rv == 0)
virReportError(VIR_ERR_ACCESS_DENIED, NULL);
return -1;
}
virObjectUnref(mgr);

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.

consequently (from 1.13 in my case) started leaving these files behind
along with '<testname>.log' files as well (which we already ignore).

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.

There are many aspects of the guest XML which result in the
SELinux driver applying file labelling. With the increasing
configuration options it is desirable to test this behaviour.
It is not possible to assume that the test suite has the
ability to set SELinux labels. Most filesystems though will
support extended attributes. Thus for the purpose of testing,
it is possible to extend the existing LD_PRELOAD hack to
override setfilecon() and getfilecon() to simply use the
'user.libvirt.selinux' attribute for the sake of testing.

To avoid confusion between the LXC driver <-> controller
monitor RPC protocol and the libvirt-lxc.so <-> libvirtd public
RPC protocol, rename the former to lxc_monitor_protocol.x
