Testing found an inventive way to cause an error at shutdown by providing the
parent name for the fc host creation using the "same name" as the HBA. Since
the code thus assumed the parent host name provided was the parent HBA and
just extracted out the host number and sent that along to the vport_destroy
this avoided checks made for equality.
So just add the equality check to that path to resolve.
While most of the APIs are okay with 16M messages, the bulk stats API
can run into the limit in big configurations. Before we devise a new
plan for this, bump this limit slightly to accomodate some more configs.
If the first console is just a copy of the first serial device we
don't need to iterate over the same device twice in order to perform
actions like security labeling, cgroup configuring, etc.
Currently only security SELinux manager was aware of this fact.

Setting the 'group_name' for a disk would falsely trigger a error path
as in commit 4b57f76502 we did not properly check the return value of
VIR_STRDUP.
Attempting to start a domain with USB hostdevs but no USB controllers
fails with the rather cryptic error
libxl: error: libxl_qmp.c:287:qmp_handle_error_response: received an
error message from QMP server: Bus 'xenusb-0.0' not found
This can be fixed by creating default USB controllers. When no USB
controllers are defined, create the number of 8 port controllers
necessary to accommodate the number of defined USB devices.
Note that USB controllers are already created as needed in the
domainAttachDevice code path. E.g. a USB controller will be created,
if necessary, when attaching a USB device with
'virsh attach-device dom usbdev.xml'.
This reverts commit 2841e675.
It turns out that adding the host_mtu field to the PCI capabilities in
the guest bumps the length of PCI capabilities beyond the 32 byte
boundary, so the virtio-net device gets 64 bytes of ioport space
instead of 32, which offsets the address of all the other following
devices. Migration doesn't work very well when the location and length
of PCI capabilities of devices is changed between source and
destination.
This means that we need to make sure that the absence/presence of
host_mtu on the qemu commandline always matches between source and
destination, which means that we need to make setting of host_mtu an
opt-in thing (it can't happen automatically when the bridge being used
has a non-default MTU, which is what commit 2841e675 implemented).
I do want to re-implement this feature with an <mtu auto='on'/>
setting, but probably won't backport that to any stable branches, so
I'm first reverting the original commit, and that revert can be pushed
to the few releases that have been made since the original (3.1.0 -
3.3.0)

If a VNC listen address is not specified in domXML, libxl
will default to 127.0.0.1, but this is never reflected in the domXML.
In the case of spice, a missing listen address resulted in listening
on all interfaces, i.e. '0.0.0.0'. If not specified, set the listen
address in virDomainGraphicsDef struct to the libxl default when
creating the frame buffer device. Additionally, set default spice
listen address to 127.0.0.1.
The current README file contents has almost no useful info, and that
which does exist is very outdated.

There's a slight problem with the current function. Assume we are
currently in a data section and we have say 42 bytes until next
section. Therefore, just before (handler) is called to fill up
the buffer with data, @want is changed to 42 to match the amount
of data left in the current section. However, after hole is
processed, we are back in data section but with incredibly small
@want size. Nobody will ever reset it back. This results in
incredible data fragmentation.

The code causes the 'offset' variable to be overwritten (possibly with
NULL if neither of the vCPUs is halted) which causes a crash since the
variable is still used after that part.
Additionally there's a bug, since strstr() would look up the '(halted)'
string in the whole string rather than just the currently processed line
the returned data is completely bogus.
Rather than switching to single line parsing let's remove the code
altogether since it has a commonly used JSON monitor alternative and
the data itself is not very useful to report.
The code was introduced in commit cc5e695bde

Start discovering the mediated devices on the host system and format the
attributes for the mediated device into the XML. Compared to the parent
device which reports generic information about the abstract mediated
devices types, a child device only reports the type name it has been
instantiated from and the IOMMU group number, since that's device
specific compared to the rest of the info that can be gathered about
mediated devices at the moment.
This patch introduces both the formatting and parsing routines, updates
nodedev.rng schema, adding a testcase as well.
The resulting mdev child device XML:
<device>
<name>mdev_4b20d080_1b54_4048_85b3_a6a62d165c01</name>
<path>/sys/devices/.../4b20d080-1b54-4048-85b3-a6a62d165c01</path>

The reason for introducing two capabilities, one for the device itself
(cap 'mdev') and one for the parent device listing the available types
('mdev_types'), is that we should be able to do
'virsh nodedev-list --cap' not only for existing mdev devices but also
for devices that support creation of mdev devices, since one day libvirt
might be actually able to create the mdev devices in an automated way
(just like we do for NPIV/vHBA).
