Commit ddd6bef4 switched to the ustar format to fix an issue where
'make dist' fails to create a tarball because we have files with
relative names longer than 100 bytes by the time you include a
'libvirt-0.9.13' prefix.  Unfortunately, even with ustar format,
the use of 'tar -ch' tries to convert symlinks to hard links,
also with a name too long (omitting the -h works, but automake
automatically passes -h); such symlinks were added in commit
6dcf98c8, which resulted in 'make dist' breaking again.  The
solution is to rename the offending symlinks to something shorter,
by shortening the entire nodeinfodata naming scheme.

* tests/nodeinfotest.c (mymain): Shorten test names.
(linuxTestNodeInfo): Accommodate new names.
* tests/nodeinfodata/*: Rename files accordingly.

Commit a56c3470 introduced a use of random numbers into seclabel
handling, but failed to initialize the random number generator
in the testsuite.  Also, fail with usual status, not 255.

* tests/seclabeltest.c (main): Initialize randomness.

used by the upcoming domainGetHostname implementation.

to query the guest's hostname.

to query a guests's hostname. Containers like LXC and OpenVZ allow to
set a hostname different from the hosts name and QEMU's guest agent
could provide similar functionality.

When reporting a system error (VIR_ERR_SYSTEM_ERROR) via
virReportSystemError, we should copy the errno value into
the 'int1' field of the virErrorPtr struct. This allows
callers to detect certain errno conditions & discard the
error

* src/util/virterror.c: Place errno value in int1 field

The previous check for YAJL would have many undesirable
consequences, the most important being that it caused the
capabilities XML to lose all <guest> elements. There is
no user visible feedback as to what is wrong in this respect,
merely a syslog message. The empty capabilities causes
libvirtd to then throw away all guest XML configs that are
stored.

This changes the code so that the check for YAJL is only
performed at the time we attempt to spawn a QEMU process

error: Failed to start domain vm-vnc
error: unsupported configuration: this qemu binary requires libvirt to be compiled with yajl

Instead of using an O(n) efficiency linked list for storing
MCS labels, use a hash table. Instead of having the list
be global, put it in the SELinux driver private data struct
to ensure uniqueness across different instances of the driver.
This also ensures thread safety when multiple hypervisor
drivers are used in the same libvirtd process

Running libvirtd unprivileged results in a warning message from
the NWFilter driver

Update the legacy Xen drivers to use virReportError instead of

The xenHypervisorInit method was called from two different
locations, during initial driver registration and also while
opening a Xen connection. The former can't report any useful
errors to the end user/app, so remove it. To ensure thread
safety use a VIR_ONCE_GLOBAL_INIT call to invoke
xenHypervisorInit from the xenHypervisorOpen method.

As per the comment, the Xen hypervisor driver is considered to
be mandatory when running privileged. When it fails to open,
we should thus return an error, not ignore it.

ensures that initialization will always take place when it is
needed, and guarantees it only occurs once. The problem is that
the code to setup a global initializer with proper error
propagation is tedious. This introduces VIR_ONCE_GLOBAL_INIT
macro to simplify this.

The Xen driver had a number of error reports which passed a

useful piece of info (the errno) was being discarded
