Commit 06f81c63 attempted to make
QEMU driver ignore the failure to relabel 'stdin_path' if it was
on NFS. The actual result was that it ignores *all* failures to
label any aspect of the VM, unless stdin_path is non-NULL and
is not on NFS.

* src/qemu/qemu_driver.c: Treat all relabel failures as terminal

They only popped up during --disable-nls build. Without this configure
option, gcc wasn't able to detect them.

* src/util/util.h
* src/util/util.c
* src/libvirt_private.syms

* docs/drvqemu.html.in (qemu): Fix typo.

* src/xen/xend_internal.c (xenDaemonFormatSxpr): Hoist verify
outside of function to avoid a -Wnested-externs warning.
* src/xen/xm_internal.c (xenXMDomainConfigFormat): Likewise.
Reported by Daniel P. Berrange.

With this file in place, opening any source file in libvirt will set up
Emacs for proper indentation.

Make sure that the QEmu process within the cgroup can access the device
file for the USB device that has to be connected to the virtual domain.

* src/xen/xen_hypervisor.c (MAX_VIRT_CPUS): Move...
* src/xen/xen_driver.h (MAX_VIRT_CPUS): ...so all xen code can see
same value.
* src/xen/xend_internal.c (sexpr_to_xend_domain_info)
(xenDaemonDomainGetVcpusFlags, xenDaemonParseSxpr)
(xenDaemonFormatSxpr): Work if MAX_VIRT_CPUS is 64 on a platform
where long is 64-bits.
* src/xen/xm_internal.c (xenXMDomainConfigParse)
(xenXMDomainConfigFormat): Likewise.

Only build statstest and reconnect if they should be used, so add them
behind the ENABLE_XEN_TESTS conditional.

Add dump_image_format[] to qemu.conf and support compressed dump
at virsh dump. coredump compression is important for saving disk space
in an environment where multiple guests run.

In general, "disk space for dump" is specially allocated and will be
a dead space in the system. It's used only at emergency. So, it's better
to have both of save_image_format and dump_image_format. "save" is done
in scheduled manner with enough calculated disk space for it.

This code reuses some of save_image_format[] and supports the same format.

Changelog:
 - modified libvirtd_qemu.aug
 - modified test_libvirtd_qemu.aug
 - fixed error handling of qemudSaveCompressionTypeFromString()

When we mount any cgroup without "-o devices", we will fail to start vms:

error: Failed to start domain vm1
error: Unable to deny all devices for vm1: No such file or directory

When we mount any cgroup without "-o cpu", we will fail to get schedinfo:
Scheduler      : posix
error: unable to get cpu shares tunable: No such file or directory

We should only use the cgroup controllers which are mounted on host.
So I add virCgroupMounted() for qemuCgroupControllerActive()

* configure.ac libvirt.spec.in: new version
* docs/news.html.in: update news page and improve format
* po/*.po*: Update po again

This is actually a workaround, to unbreak make check on systems
without VirtualBox.

This partly reverts df90ca76.

Don't disable the VirtualBox driver when configure can't find
VBoxXPCOMC.so, rely on detection at runtime again instead.

Keep --with-vbox=/path/to/virtualbox intact, added to for:
https://bugzilla.redhat.com/show_bug.cgi?id=609185

Detection order for VBoxXPCOMC.so:

1. VBOX_APP_HOME environment variable
2. configure provided location
3. hardcoded list of known locations
4. dynamic linker search path

Also cleanup the glue code and improve error reporting.

Updated the descriptions for managedsave and start in virsh and
the virsh man page, and also for managedsave-remove in the virsh
man page.

fix warning
  CC     libvirt_util_la-virtaudit.lo
cc1: warnings being treated as errors
util/virtaudit.c: In function 'virAuditEncode':
util/virtaudit.c:146: error: implicit declaration of function 'virAsprintf' [-Wimplicit-function-declaration]
util/virtaudit.c:146: error: nested extern declaration of 'virAsprintf' [-Wnested-externs]

The 2nd and 3rd hunk show the only double-closed file descriptor code part that I found while trying to clean up close(). The first hunk seems a harmless cleanup in that same file.

https://bugzilla.redhat.com/show_bug.cgi?id=638285 - when migrating
a guest, it was very easy to provoke a race where an application
could query block information on a VM that had just been migrated
away.  Any time qemu code obtains a job lock, it must also check
that the VM was not taken down in the time where it was waiting
for the lock.

* src/qemu/qemu_driver.c (qemudDomainSetMemory)
(qemudDomainGetInfo, qemuDomainGetBlockInfo): Check that vm still
exists after obtaining job lock, before starting monitor action.

During virtual network startup, the iptables rule that allows tftp
traffic is only added if network->def->tftproot is non-empty, but when
the virtual network is destroyed, we had been unconditionally trying
to delete the rule. This was harmless, except that it created a bogus
error message.

This patch conditionalizes the delete command in the same manner that
the insert command is already conditionalized.

* docs/api_extension/{0013,0014}*.patch: Rename to shorter files.
* docs/api_extension.html.in: Reflect rename.

Reordered the bindings into alphabetical order, added a link to
the php-libvirt source on Github, plus gave the direct package
names needed for Python usage on RHEL/Fedora, and Ubuntu.

Commit 9bd3cce0 added virFork and
virDriverLoadModule to libvirt_private.syms, but virFork didn't have
a body on Win32 and virDriverLoadModule was already correctly
exported conditional via libvirt_driver_modules.syms.

Add auditing of all initial disk/net assignments to QEMU guests
at startup. Add auditing for all hotplug & unplug events and
disk media changes.

* src/qemu/qemu_driver.c: Add disk/net resource auditing

Add auditing of the allocated security label in the QEMU driver
VM startup code

* src/qemu/qemu_driver.c: Audit security label

Add audit hooks to report all start and stop events on QEMU
guest domains.

* src/qemu/qemu_driver.c: Audit start/stop events

* src/util/virtaudit.h: Add printf format attribute annotation

Add a helper API for ecscaping the value in audit log
messages

* src/util/virtaudit.h, src/util/virtaudit.c,
  src/libvirt_private.syms: Add virAuditEncode

This reverts commit b8e2de88
The hooks will be re-added in the QEMU driver itself.

* src/security/security_selinux.c: Remove audit hooks

Revert most of commit a8b5f9bd.
The audit hooks will be re-added directly in the QEMU driver code
in a future commit

* daemon/remote.c: Remove all audit logging hooks
* src/qemu/qemu_driver.c: Remove all audit logging hooks

*src/xen/xend_internal.c: fix a couple of comments in function descriptions

There are a 58 docs files, so adding an autogenerated Table Of
Contents to them all will take some time.  This is the first
piece of the work done.

* tools/virsh.c (opts_memtune): All other options in virsh use -
for separating words.

A missing shell was noisy, and the use of command to decipher a
shell's absolute path requires "" rather than ''.

* configure.ac (lv_cv_wrapper_shell): Fix logic errors if candidate
shell is not available.
* .gitignore: Ignore file created when /bin/sh is old dash.
Reported by Matthias Bolte.

* cfg.mk (sc_prohibit_trailing_blank_lines): Delete; this is
adequately covered by maint.mk's sc_prohibit_empty_lines_at_EOF.
* .x-sc_prohibit_empty_lines_at_EOF: New file, to exempt raw
patches.
* Makefile.am (EXTRA_DIST): Include new exemption.

* docs/api_extension/*: Replace example files.
* docs/api_extension.html.in: Rewrite to match new example files.
