On RHEL 5, I got:

Add necessary handling code for the new s390 CCW address type to
virDomainDeviceInfo. Further, introduce  memory management, XML
parsing, output formatting and range validation for the new
virDomainDeviceCCWAddress type.

Adjustment for 'c059cdea' due to older compiler complaint about pm
not being initialized even though the j&7 == 0 does the trick.

This just simply changes nodeDeviceLookupByWWN to be not static,
and its name into nodeDeviceLookupSCSIHostByWWN. And use that for
udev and HAL backends.

Like virNodeDeviceCreateXML, virNodeDeviceLookupSCSIHostByWWN
has to be treated specially when generating the RPC codes. Also
new rules are added in fixup_name to keep the name SCSIHostByWWN.

Since the name (like scsi_host10) is not stable for vHBA, (it can
be changed either after recreating or system rebooting), current
API virNodeDeviceLookupByName is not nice to use for management app
in this case. (E.g. one wants to destroy the vHBA whose name has
been changed after system rebooting, he has to find out current
name first).

Later patches will support the persistent vHBA via storage pool,
with which one can identify the vHBA stably by the wwnn && wwpn
pair.

So this new API comes.

The security manager drivers are not allowed to call back
out to top level security manager APIs, since that results
in recursive mutex acquisition and thus deadlock. Remove
calls to virSecurityManagerGetModel from SELinux / AppArmor
drivers

Turns out the issue regarding ptr_arith and sign_exension weren't false
positives. When shifting an 'unsigned char' as a target, it gets promoted
to an 'int'; however, that 'int' cannot be shifted 32 bits which was how
the algorithm was written. For the ptr_arith rather than index into the
cpumap, change the to address as necessary and assign directly.

Arguments for driver entry points are checked in libvirt.c, so no need to
check again. Make function entry points consistent. Don't type caste the
privateData.

Commit id '87b4c10c' moved the VIR_ALLOC_N, but didn't check if 'cpuset'

Currently the APIs for managing the shared disk list take
a virHashTablePtr as the primary argument. This is bad
because it requires the caller to deal with locking of
the QEMU driver. Switch the APIs to take the full
virQEMUDriverPtr instance

Add locking to virSecurityManagerXXX APIs, so that use of the
security drivers is internally serialized. This avoids the need
to rely on the global driver locks to achieve serialization

To enable locking to be introduced to the security manager
objects later, turn virSecurityManager into a virObjectLockable

From qemu's point of view these are still just tap devices, so there's
no reason they shouldn't work with vhost-net; as a matter of fact,
Raja Sivaramakrishnan <srajag00@yahoo.com> verified on libvir-list
that at least the qemu_command.c part of this patch works:

(the hotplug case is extrapolation on my part).

The virNetworkObjUpdateParseFile() function was not freeing the xml
variable, leaving us with a memory leak.

The 'driver->caps' pointer can be changed on the fly. Accessing
it currently requires the global driver lock. Isolate this
access in a single helper, so a future patch can relax the
locking constraints.

To avoid confusion between 'virCapsPtr' and 'qemuCapsPtr'
do some renaming of various fucntions/variables. All
instances of 'qemuCapsPtr' are renamed to 'qemuCaps'. To
avoid that clashing with the 'qemuCaps' typedef though,
rename the latter to virQEMUCaps.

The virCgroupPtr instance APIs are safe to use without locking
in the QEMU driver, since all internal state they rely on is
immutable. Update the comment to reflect this.

We are wrapping it in ignore_value() anyway.

We are requesting for stderr catching for all cases in
virFileWrapperFdNew(). There is no need to have a separate
function just to report an error, esp. when we can do it in
virFileWrapperFdClose().

Need to initialize 'usage' and 'critical' since the VIR_DEBUG will
attempt to use them.

The qemuParseGlusterString() replaced dst->src without a VIR_FREE() of
what was in there before.

The qemuBuildCommandLine() did not properly free the boot_buf depending
on various usages.

The qemuParseCommandLineDisk() had numerous paths that didn't clean up
the virDomainDiskDefPtr def properly. Adjust the logic to go through an
error: label before cleanup in order to free the resource.

The 'virtPortInterfaceID' was not VIR_FREE()'d

The 'trunk' is filled in with virXPathString() value, but was
never VIR_FREE()'d.

Coverity noted that in the retry logic loop if res had been set, then
it could be leaked so add a VIR_FREE(res) prior to retry.
