By indenting code inside of comments, it gets recognized as a
code block when generating the HTML documentation.

See libvirt-libvirt.html#virStreamSend for the effect.

Wrap pre-formatted example code in <code> elements. This works
similar to Markdown[1] code blocks[2]:

Every line indented with at least 2 spaces is considered a code
block and gets wrapped in <pre> and <code> tags.

Look at the documentation for e.g. virStreamSend for before-and-after
effects.

The following sequence

 1. Define a persistent QMEU guest
 2. Start the QEMU guest
 3. Stop libvirtd
 4. Kill the QEMU process
 5. Start libvirtd
 6. List persistent guests

At the last step, the previously running persistent guest
will be missing. This is because of a race condition in the
QEMU driver startup code. It does

 1. Load all VM state files
 2. Spawn thread to reconnect to each VM
 3. Load all VM config files

Only at the end of step 3, does the 'virDomainObjPtr' get
marked as "persistent". There is therefore a window where
the thread reconnecting to the VM will remove the persistent
VM from the list.

The easy fix is to simply switch the order of steps 2 & 3.

In addition to this though, we must only attempt to reconnect
to a VM which had a non-zero PID loaded from its state file.

The 'error' cleanup block in qemuProcessReconnect() had a
'return' statement in the middle of it. This caused a leak
of virConnectPtr & virQEMUDriverConfigPtr instances. This
was identified because netcf recently started checking its

The QEMU backend was disabled on Mac OS X without a reason in the code
and due to refactors its difficult to understand when/why it was
disabled. With QEMU being supported on Mac OS X there is no reason to
disable QEMU on this platform.

To ensure proper processing by virGetUserID() and virGetGroupID()
of a uid/gid add a "+" prior to the uid/gid to denote it's really
a uid/gid for the label.

The rbd code had a confusing typedef ending in Ptr that was not
actually a pointer, which made the rest of the code harder to
read.  This fixes things to actually pass by pointer rather than
by copy.

For inexplicable reasons, many of the 3rd party package deps
were left against the 'libvirt-daemon' RPM when the drivers
were split out. This makes a minimal install heavier that
it should be. Push them all down into libvirt-daemon-driver-XXX
so they're only pulled in when truly needed

With this change applied, a minimal install of just the
libvirt-daemon-driver-lxc RPM is reduced by 41 MB on a
Fedora 19 host.

Commit '922b7fda' resulted in two DEADCODE warnings from Coverity in
remoteDispatchAuthPolkit and virAccessDriverPolkitFormatProcess.
Commit '604ae657' modified the daemon.c code to remove the deadcode
issue, but did not do so for viracessdriverpolkit.c. This just mimics
the same changes

Commit e962a579 added 'attach-disk --shareable', even though we
already had 'attach-disk --mode=shareable'.  Worse, if the user
types 'attach-disk --mode=readonly --shareable', we create
non-sensical XML.  The best solution is just to undocument the
duplicate spelling, by having it fall back to the preferred

On RHEL 5, make syntax-check was failing because even strings like
'int isTempChain' matched the 'int i' rule.  To be honest, I haven't
found the root cause, but the change added makes it work as expected
and keeps the proper behavior on newer systems as well.

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.

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

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?
