Make the decision based on the usage of childBuf buffer.
This fixes the oddity in the test case introduced by commit c1c4d0d
where we would format an empty pair tag.
We need to decide whether to format <controller> as a single tag
or if it has any subelements.
Rewrite the function to use a separate buffer for subelements,
to make adding new options easier.
After some discussion on and off the linux-audit mailing list, we
should use different fields for the audit messages.

The memset() was resetting only 30 bytes in the array (size of the

let's just reset it by its size.

When searching for an NPIV capable fc_host, not only does there need to
be an "fc_host" capability with the specified wwnn/wwpn or fabric_wwn,
but that scsi_host must be vport capable; otherwise, one could end up
picking an exising vHBA/NPIV which wouldn't be good.
Currently not a problem since scsi_hosts are in an as found forward linked
list and the vport capable scsi_hosts will always appear before a vHBA by
definition. However, in the near term future a hash table will be used to
lookup the devices and that could cause problems for these algorithms.

Alter the algorithm to return a list of matching names rather than a

Also alter the error message on failure to include the mac that wasn't
found.

for i in `seq 0 1`; do
echo 63 > /sys/class/net/<interface>/device/sriov_numvfs
done
libvirtd will then report "udev_monitor_receive_device returned NULL"
error because the netlink socket buffer is not big enough (using GDB on
libudev confirmed this with ENOBUFFS) and thus some udev events were
dropped. This results in some devices being missing in the nodedev-list
output. This patch overrides the system's rmem_max limit but for that,
we need to make sure we've got root privileges.

QEMU will likely report the details of it shutting down, particularly
whether the shutdown was initiated by the guest or host. We should
forward that information along, at least for shutdown events. Reset

extra constants that might not be used. It can be added later on.

The number of records that virConnectGetAllDomainStats can return per
domain is currently limited to 4096. This is quite low -- for
example, a single guest with ~320 disks will hit this limit. This
increases the limit to make it much larger. Note that
VIR_NET_MESSAGE_MAX still protects the total message size in the case
where there are many domains and many disks per domain.
I tested this using a guest with 500 disks with no issues.
