The reconnect attribute for chardev devices in QEMU is used to
configure the reconnect timeout in seconds.  Setting '0' value disables
the reconnect functionality thus we don't allow to set '0' for QEMU.
To disable the reconnect user should use <reconnect enabled='no'/>.

3 out of 4 uses of gl_WARN_ADD() were incorrectly adding "" around
the argument, which in turn resulted in the argument being used
unquoted (configure had gl_positive=""-fstack-protector-all"",
rather than the intended gl_positive="-fstack-protector-all").

Commit 94c465d0 refactored the logging setup phase but introduced an
issue, where the daemon ignores verbose mode when there are no outputs
defined and the default must be used. The problem is that the default
output was determined too early, thus ignoring the potential '--verbose'
option taking effect. This patch postpones the creation of the default
output to the very last moment when nothing else can change. Since the
default output is only created during the init phase, it's safe to leave
the pointer as NULL for a while, but it will be set eventually, thus not
affecting runtime.
Patch also adjusts both the other daemons.

We can't retrieve the isolation group of a device that's not present
in the system. However, it's very common for VFs to be created late
in the boot, so they might not be present yet when libvirtd starts,
which would cause the guests using them to disappear.

Moreover, for other architectures and even ppc64 before isolation
groups were introduced, it's considered perfectly fine to configure a
guest to use a device that's not yet (or no longer) available to the
host, with the obvious caveat that such a guest won't be able to
start before the device is available.

In order to be consistent, when a device's isolation group can't be
determined fall back to not isolating it rather than erroring out or,
worse, making the guest disappear.

While formatting disk or chardev element they both uses
virDomainDiskSourceDefFormatSeclabel() function which also closes
the source element.  This is not extendable.

Use the new virXMLFormatElement() to properly format the source
element with possible child elements.

As a side effect it fixes a bug in disk source formatting.

Fix the warning generated on PPC by virt-host-validate for IOMMU.
In case of PPC, IOMMU in the host kernel either has it or it's not
compiled in. The /sys/kernel/iommu_groups check is good enough to

When parsing the config, we look for the SCSI controllers one by one,
remembering their models, then let virDomainDefAddImplicitDevices
add them if any SCSI disk is using them.

Since these controllers are not really implicit (they are present
in the source config), add them explicitly.

This patch maintains the behavior of not adding a controller
if it was present in the config, but no disk was using it.

This also resolves the memory leak of virVMXParseConfig overwriting
the video device added by calling virDomainDefAddImplicitDevices
before the parsing is finished.

For selected hostdev types, we validate that the address type
matches the subsystem type when parsing the XML.

Move it to the validation phase, to allow extending the checks
to other subsystem types without making existing domains disappear.

If we jump to the error: label and @secbuf is allocated, then it's not
free'd at all.

At the time the check was written virtuozzo did not use disabled items in boot
order configuration. Boot items were always enabled. Now they can be disabled
as well. Supporting such items is easy - they just should be ignored.

HTML5 obsoletes the 'name' attribute in favor of 'id',
and our TOC generator apparently follows the recommendation
to the letter, resulting in a broken TOC if you use the
old-school attribute.

When parsing bootable devices, we maintain a bitmap of used
<boot order=""> elements. Use it in the post-parse function
to figure out whether the user tried to mix per-device and
per-domain boot elements.

This removes the need to count them twice.

Rename the original function to virDomainDefPostParseInternal
to allow adding arguments that will be only used by the internal
version.
