When I quit the process which only register VIR_DOMAIN_EVENT_ID_REBOOT,
I got error like:
"libvirt: XML-RPC error : internal error: domain event 0 not registered".
Then I add the following code, it fixed.

Commit d76227be added functions virDomainCreateWithFiles and
virDomainCreateXMLWithFiles, but there was a little piece missing in
python bindings.  This patch fixes proper passing of file descriptors
in the overwrites of these functions.

On systems where gnutls uses libgcrypt, I'm seeing the following
build failure

libvirt.c:314: error: variable 'virTLSThreadImpl' has initializer but incomplete type
libvirt.c:319: error: 'GCRY_THREAD_OPTION_PTHREAD' undeclared here (not in a function)
...

Fix by undefining WITH_GNUTLS_GCRYPT in config-post.h

After commit 3e2f27e1, I've noticed build failures of virt-login-shell
when libapparmor-devel is installed on the build host

CCLD     virt-login-shell
../src/.libs/libvirt-setuid-rpc-client.a(libvirt_setuid_rpc_client_la-vircommand.o):
In function `virExec':
/home/jfehlig/virt/upstream/libvirt/src/util/vircommand.c:653: undefined
reference to `aa_change_profile'
collect2: error: ld returned 1 exit status

I was about to commit an easy fix under the build-breaker rule
(build-fix-1.patch), but thought to extend the notion of SECDRIVER_LIBS
to SECDRIVER_CFLAGS, and use both throughout src/Makefile.am where it
makes sense (build-fix-2.patch).

Should I just stick with the simple fix, or is something along the lines
of patch 2 preferred?

Regards,
Jim

Subject: [PATCH] build: fix virt-login-shell build with apparmor

With libapparmor-devel installed, virt-login-shell fails to link

CCLD     virt-login-shell
../src/.libs/libvirt-setuid-rpc-client.a(libvirt_setuid_rpc_client_la-vircommand.o): In function `virExec':

collect2: error: ld returned 1 exit status

Fix by linking libvirt_setuid_rpc_client with previously determined
SECDRIVER_LIBS in src/Makefile.am.  While at it, introduce SECDRIVER_CFLAGS
and use both throughout src/Makefile.am where it makes sense.

The libvirt.so library has far too many library deps to allow
linking against it from setuid programs. Those libraries can
do stuff in __attribute__((constructor) functions which is
not setuid safe.

The virt-login-shell needs to link directly against individual
files that it uses, with all library deps turned off except
for libxml2 and libselinux.

Create a libvirt-setuid-rpc-client.la library which is linked
to by virt-login-shell. A config-post.h file allows this library
to disable all external deps except libselinux and libxml2.

Care must be taken accessing env variables when running
setuid. Introduce a virGetEnvAllowSUID for env vars which
are safe to use in a setuid environment, and another
virGetEnvBlockSUID for vars which are not safe. Also add
a virIsSUID helper method for any other non-env var code
to use.

The virConnectDomainXMLToNative API should require 'connect:write'
not 'connect:read', since it will trigger execution of the QEMU
binaries listed in the XML.

Also make virConnectDomainXMLFromNative API require a full
read-write connection and 'connect:write' permission. Although the
current impl doesn't trigger execution of QEMU, we should not
rely on that impl detail from an API permissioning POV.

(cherry picked from commit 15fac93b)

Since 76b644c3 when the support for RAM filesystems was introduced,
libvirt accepted the following XML:
<source usage='1024' unit='KiB'/>

This was parsed correctly and internally stored in bytes, but it
was formatted as (with an extra 's'):
<source usage='1024' units='KiB'/>
When read again, this was treated as if the units were missing,
meaning libvirt was unable to parse its own XML correctly.

The usage attribute was documented as being in KiB, but it was not
scaled if the unit was missing. Transient domains still worked,
because this was balanced by an extra 'k' in the mount options.

This patch:
Changes the parser to use 'units' instead of 'unit', as the latter
was never documented (fixing persistent domains) and some programs
(libvirt-glib, libvirt-sandbox) already parse the 'units' attribute.

Removes the extra 'k' from the tmpfs mount options, which is needed
because now we parse our own XML correctly.

Changes the default input unit to KiB to match documentation, fixing:

(cherry picked from commit 3e8343e1)

This fixes the following error:
  error : virGetUserEnt:703 : Failed to find user record for uid '32654'

'32654' (it's random and varies) comes from getsockopt with
LOCAL_PEERCRED option. getsockopt returns w/o error but seems
to not set any value to the buffer for uid.

For Mac OS X, LOCAL_PEERCRED has to be used with SOL_LOCAL level.
With SOL_LOCAL, getsockopt returns a correct uid.

Note that SOL_LOCAL can be found in
/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/sys/un.h.

(cherry picked from commit 5a468b38)

The virConnectPtr is passed around loads of nwfilter code in
order to provide it as a parameter to the callback registered
by the virt drivers. None of the virt drivers use this param
though, so it serves no purpose.

Avoiding the need to pass a virConnectPtr means that the
nwfilterStateReload method no longer needs to open a bogus
QEMU driver connection. This addresses a race condition that
can lead to a crash on startup.

The nwfilter driver starts before the QEMU driver and registers
some callbacks with DBus to detect firewalld reload. If the
firewalld reload happens while the QEMU driver is still starting
up though, the nwfilterStateReload method will open a connection
to the partially initialized QEMU driver and cause a crash.

So far the virNetDevBandwidthEqual() expected both ->in and ->out items
to be allocated for both @a and @b compared. This is not necessary true
for all our code. For instance, running 'update-device' twice over a NIC
with the very same XML results in SIGSEGV-ing in this function.

Commit 27e81517 set the payload size to 256 KB, which is
actually the max packet size, including the size of the header.

Reduce this by VIR_NET_MESSAGE_HEADER_MAX (24) and set
VIR_NET_MESSAGE_LEGACY_PAYLOAD_MAX to 262120, which was the original
value before increasing the limit in commit eb635de1.

The problem is described by [0] but its effect on libvirt is that
starting a container with a full distro running systemd after having
stopped it simply fails.

The container cleanup now calls the machined Terminate function to make
sure that everything is in order for the next run.

The memory size in virNodeGetInfo python API binding is reported in MiB

simply fix it. Document this sad fact as known bug.

Add support for VMware Fusion in the existing VMware driver.  Connect

Currently the VMware version check code only supports two types of
VMware backends, Workstation and Player. But in the near future we will
have an additional one so we need to support more. Additionally, we
discover and cache the path to the vmrun binary so we should use that
path when using the corresponding binary from the VMware VIX SDK.

On some systems (linux, cygwin and gnukfreebsd) rpcgen generates files

Hence, on those systems we need to post-process the files by the
rpc/genprotocol.pl perl script. At the beginning of the script the OS is
detected via $^O perl variable. From my latest build on FreeBSD I see we
need to fix the code there too. On FreeBSD the variable contains
