5baa463541 avoid malfunction when virFileResolveLink is applied to non-POSIX FS
The virFileResolveLink utility function relied on the POSIX guarantee
that stat.st_size of a symlink is the length of the value.  However,
on some types of file systems, it is invalid, so do not rely on it.
Use gnulib's areadlink module instead.
* bootstrap (modules): Add areadlink.
* src/util/util.c: Include "areadlink.h".
Let areadlink perform the readlink and malloc.
* configure.in (AC_CHECK_FUNCS): Remove readlink.  No need,
since it's presence is guaranteed by gnulib.

11f6cc3279 xm_internal.c: remove misleading dead code
* src/xen/xm_internal.c (xenXMConfigGetULong): Remove useless and
misleading test (always false) for val->str == NULL before code that
always dereferences val->str.  "val" comes from virConfGetValue, and
at that point, val->str is guaranteed to be non-NULL.
(xenXMConfigGetBool): Likewise.
* src/util/conf.c (virConfSetValue): Ensure that vir->str is never NULL,
not even if someone tries to set such a value via virConfSetValue.

d0857c0132 Fix install location for Python bindings
Commit 66137344fe changed the Python detection
mechanism in configure to use AM_PATH_PYTHON. This results in a changed
install location for the Python bindings, at least on Fedora 12 64bit systems.

Before this commit libvirt.py and libvirtmod.so were installed to

  /usr/lib64/python2.6/site-packages

After this commit they are installed to

  /usr/lib/python2.6/site-packages

Mixed Python packages (containing *.py and *.so files) should be installed to
the pyexecdir directory detected by AM_PATH_PYTHON.

This restores the install location from before the AM_PATH_PYTHON commit.

* configure.in: remove unnecessary pythondir export
* python/Makefile.am: switch from pythondir to pyexecdir

This patch fixes the problem reported in:

https://bugzilla.redhat.com/show_bug.cgi?id=509306

option, but that's not the case in the current head.  This patch makes
vol-path behave the same way as vol-delete

* tools/virsh.c: Modified vol-path to use the same logic as vol-delete,

  instead of restarting it if --crash is passed.

60e8977fdd Get QEMU pty paths from the monitor
This change makes the QEMU driver get pty paths from the output of the
monitor 'info chardev' command. This output is structured, and contains
both the name of the device and the path on the same line. This is
considerably more reliable than parsing the startup log output, which
requires the parsing code to know which order QEMU will print pty
information in.

Note that we still need to parse the log output as the monitor itself
may be on a pty. This should be rare, however, and the new code will
replace all pty paths parsed by the log output method once the monitor
is available.

* src/qemu/qemu_monitor.(c|h) src/qemu_monitor_text.(c|h): Implement
  qemuMonitorGetPtyPaths().

2597f8ecc9 Suppress cgroup error message on sucess startup
Even if qemudStartVMDaemon suceeds, an error was logged such as
'qemuRemoveCgroup:1778 : internal error Unable to find cgroup for'.

ensure that old cgroup does not remain. This workaround makes
sense but leaving an error message may confuse users.

5de41c06a4 retrieve paused/running state at migration start
This patch fixes the bug where paused/running state is not
transmitted during migration.  As a result, in the QEMU driver
for example the machine was always started on the destination
end.

In order to do so, just read the state and if it is appropriate and
set the VIR_MIGRATE_PAUSED flag.

* src/libvirt.c (virDomainMigrateVersion1, virDomainMigrateVersion2):
  Automatically add VIR_MIGRATE_PAUSED when appropriate.
* src/xen/xend_internal.c (xenDaemonDomainMigratePerform): Give a nicer

4ecf9c653e remove iptablesReloadRules() and related code
We don't use this method of reloading rules anymore, so we can just
kill the code.

3b3305d859 remove all traces of lokkit support
Long ago we tried to use Fedora's lokkit utility in order to register
our iptables rules so that 'service iptables restart' would
automatically load our rules.

There was one fatal flaw - if the user had configured iptables without
lokkit, then we would clobber that configuration by running lokkit.

We quickly disabled lokkit support, but never removed it. Let's do
that now.

The 'my virtual network stops working when I restart iptables' still
remains. For all the background on this saga, see:

  https://bugzilla.redhat.com/227011

* src/util/iptables.c: remove lokkit support

* configure.in: remove --enable-lokkit

* libvirt.spec.in: remove the dirs used only for saving rules for lokkit

534664c372 reload iptables rules on libvirtd restart
This is the expected behaviour, I think - reloading libvirtd should
be a subset of restarting it.

Note, we reload the rules after we've determined which networks
are active (because we only add the rules for active networks)
and before we start autostart networks (to avoid re-adding the
rules).

98895e9386 reload iptables rules simply by re-adding them
Currently, when we add iptables rules, we keep them on a list so that
we can easily reload them on e.g. 'service libvirtd reload'.

However, we don't save this list to disk, so if libvirtd is restarted
we lose the ability to reload the rules.

The fix is simple - just re-add the damn things on reload.

Note, we delete the rules before re-adding them, just like the current
behaviour of iptRulesReload().

* src/network/bridge_driver.c: re-add the iptables rules on reload.

cce1998a64 Make QEMU text monitor parsing more robust
The QEMU 0.10.0 release (and possibly other 0.10.x) has a bug where
it sometimes/often forgets to display the initial monitor greeting
line, soley printing a (qemu).  This in turn confuses the text
console parsing because it has a '(qemu)' it is not expecting. The
confusion results in a negative malloc. Bad things follow.

This re-writes the text console handling to be more robust. The key
idea is that it should only look for a (qemu), once it has seen the
original command echo'd back. This ensures it'll skip the bogus stray
(qemu) with broken QEMUs.

* src/qemu/qemu_monitor.c: Add some (disabled) debug code
