Introduce use of a virDomainDefPtr in the domain lifecycle
APIs to simplify introduction of ACL security checks.
The virDomainPtr cannot be safely used, since the app
may have supplied mis-matching name/uuid/id fields. eg
the name points to domain X, while the uuid points to
domain Y. Resolving the virDomainPtr to a virDomainDefPtr
ensures a consistent name/uuid/id set.

Commit f60a50c7 intended to remove the warning only, but not with
the "return 0" together.

The shunloadStart function didn't check the status of virInitialize which
was flagged by Coverity.  Adjust the function and shunloadtest in order
to handle the situation.

The return from virInitialize() needs to be checked.

In 84c59ffa I've tried to fix changing ejectable media process. The
process should go like this:

1) we need to call 'eject' on the monitor
2) we should wait for 'DEVICE_TRAY_MOVED' event
3) now we can issue 'change' command

However, while waiting in step 2) the domain monitor was locked. So
even if qemu reported the desired event, the proper callback was not
called immediately. The monitor handling code needs to lock the
monitor in order to read the event. So that's the first lock we must
not hold while waiting. The second one is the domain lock. When
monitor handling code reads an event, the appropriate callback is
called then. The first thing that each callback does is locking the
corresponding domain as a domain or its device is about to change
state. So we need to unlock both monitor and VM lock. Well, holding
any lock while sleep()-ing is not the best thing to do anyway.

Got lost in commit e6ab1009.

To ensure we don't regress and cause the need for further
cleanups, add a 'make syntax-check' rule that ensures new
files have proper copyright contents.

You should also include a copy of the license itself somewhere in the

GNU programs the license is usually in a file called COPYING.

If you are releasing your program under the LGPL, you should also
include the text version of the LGPL, usually in a file called
COPYING.LESSER. Please note that, since the LGPL is a set of

both licenses so users have all the materials they need to understand

Several files called out COPYING or COPYING.LIB instead of using

Currently, the openvzDomainSetNetwork function constructs an
array of strings representing a command line for VZCTL binary.
This is a overkill since our virCommand APIs can cover all the
functionality. Moreover, the function is not following our
structure where return value is set to -1 initially, and after
all operations succeeded then it is set to zero.

Since 0d70656a, it starts to access the sysfs files to build
the qemu command line (by virSCSIDeviceGetSgName, which is to find
out the scsi generic device name by adpater:bus:target:unit), there
is no way to work around, qemu wants to see the scsi generic device
like "/dev/sg6" anyway.

And there might be other places which need to access sysfs files
when building qemu command line in future.

Instead of increasing the arguments of qemuBuildCommandLine, this
introduces a new callback for qemuBuildCommandLine, and thus tests
can register their own callbacks for sysfs test input files accessing.

* src/qemu/qemu_command.h: (New callback struct
                            qemuBuildCommandLineCallbacks;
                            extern buildCommandLineCallbacks)
* src/qemu/qemu_command.c: (wire up the callback struct)
* src/qemu/qemu_driver.c: (Use the new syntax of qemuBuildCommandLine)
* src/qemu/qemu_hotplug.c: Likewise
* src/qemu/qemu_process.c: Likewise
* tests/testutilsqemu.[ch]: (Helper testSCSIDeviceGetSgName;
                             callback struct testCallbacks;)
* tests/qemuxml2argvtest.c: (Use testCallbacks)
* src/tests/qemuxmlnstest.c: (Like above)

Changes:
  * Remove useless comments
  * Remove useless blank lines
  * If the struct member is a enum type, comment it like
    /* enum fooBar */
  * Break the long lines
  * Prefer the common function style for the inline function

Uses the 4 spaces for indention.

Changes:
  * Remove the useless space in "for" statement (e.g.
    for (i = 0 ; i < something ; i++)

  * Change the function's style to:
    void
    foo(bar)
    {
        printf("foo is not bar\n");
    }

  * Don't lose "{}" for "if...else" branches if one of the branch
    has more than one line block. Example of the old ones:
    if (a) {
        printf("a is not funny");
    } else
        printf("a is funny");

  * Remove the 1 space before "goto" label.

  * Remove the useless blank line(s)

  * Add blank line if it can make the code more clear to eyes.

As the name parameter can be NULL the error message can only contain it
conditionally.

 #kill -STOP `pidof qemu-kvm`
 #virsh destroy $guest --graceful
 error: Failed to destroy domain testVM
 error: An error occurred, but the cause is unknown

With --graceful, SIGTERM always is emitted to kill driver
process, but it won't success till burning out waiting time
in case of process being stopped.
But domain destroy without --graceful can work, SIGKILL will
be emitted to the stopped process after 10 secs which always
kills a process even one that is currently stopped.
So report an error after burning out waiting time in this case.

Just like previous patches, this changes qemuCheckSharedDisk
into qemuCheckSharedDevice, which takes a virDomainDeviceDefPtr
argument instead.

Running make check in a VPATH configured build directory fails
in fchosttest as the test data files are searched for relative to

Change bbe97ae9 caused the
QEMU driver to ignore ENOENT errors from cgroups, in order
to cope with missing /proc/cgroups. This is not good though
because many other things can cause ENOENT and should not
be ignored. The callers expect to see ENXIO when cgroups
are not present, so adjust the code to report that errno
when /proc/cgroups is missing

This reverts commit 940c6f10.

libxl expects the event handler to free the event passed to it.  From
libxl_event.h:

   event becomes owned by the application and must be freed, either
   by event_occurs or later

Xen 4.3 fixes a mistake in the libxl event handler signature where the
event owned by the application was defined as const.  Detect this and
define the libvirt libxl event handler signature appropriately.
