Commit 55320c23 introduced a new test for VNC to test if
vnc_auto_unix_socket is set in qemu.conf, but forget to enable it in
qemuxml2argvtest.c.
This patch also moves the code in qemuxml2xmltest.c next to other VNC
tests and refactor the test so we also check the case for parsing active
XML.

All callers of cpuGetModels expect @models to be NULL-terminated. Once
both x86GetModels and ppc64GetModels were fixed to meet this
expectation, we can explicitly document it.

The architecture specific loaders are now called with a list of all
elements of a given type (rather than a single element at a time). This
avoids the need to reallocate the arrays in CPU maps for each element.

There's no reason for keeping the models in a linked list. Especially
when we know upfront the total number of models we are loading.
As a nice side effect, this fixes ppc64GetModels to always return a
NULL-terminated list of models.

For some disk types (SD), we want to emit the syntax
we used for disks before -device was available even
if QEMU supports -device.
Use the qemuDiskBusNeedsDeviceArg helper to figure out
whether to use the old or new syntax.
Name the validation function distinctively since it's called in the
parser. Later patches will add function that will validate disk
definitions that are invalid but need to be parsed to avoid losing
domains.
Seems recent versions of Coverity have (mostly) resolved the issue using
ternary operations in VIR_FREE (and now VIR_DISPOSE*) macros. So let's
just remove it and if necessary handle one off issues as the arise.
Rather than return 0/-1 and/or a pointer to some memory, adjust the
helper to just return the allocated structure or NULL on failure.
Adjust the callers in order to handle that

If we get to the error: label and clear out the *virtual_functions[]
pointers and then return w/ error to the caller - the caller has it's
own cleanup of the same array in the out: label which is keyed off the
value of num_virt_fns, which wasn't reset to 0 in the called function
leading to a possible problem.
Just clear the value (found by Coverity)

If the stats for a block device can't be acquired from qemu we've
fallen back to loading them from the file on the disk in libvirt.
If qemu is not cooperating due to being stuck on an inaccessible NFS
share we would then attempt to read the files and get stuck too with
the VM object locked. All other APIs would eventually get stuck waiting
on the VM lock.
Avoid this problem by skipping the block stats if the VM is online but
the monitor did not provide any stats.

Some Intel processor families (e.g. the Intel Xeon processor E5 v3
family) introduced some RDT (Resource Director Technology) features
to monitor or control shared resource. Among these features, MBM
(Memory Bandwidth Monitoring), which is build on the CMT (Cache
Monitoring Technology) infrastructure, provides OS/VMM a way to
monitor bandwidth from one level of cache to another.
With current perf framework, this patch adds support to perf event
for MBM.

Finally wire-up virAdmServer{Get,Set}ClientLimits APIs into virt-admin client.

Signed-off-by: Erik Skultety <eskultet@redhat.com>
Opposite operation to virAdmServerGetClientLimits. Understandably though,
setting values for current number of clients connected or still waiting
for authentication does not make sense, since changes to these values are event
dependent, i.e. a client connects - counter is increased. Thus only the limits
to maximum clients connected and waiting for authentication can be set. Should
a request for other controls to be set arrive (provided such a setting will
be first introduced to the config), the set of configuration controls can be
later expanded (thanks to typed params). This patch also introduces a
constraint that the maximum number of clients waiting for authentication has to
be less than the overall maximum number of clients connected and any attempt to
violate this constraint will be denied.
Signed-off-by: Erik Skultety <eskultet@redhat.com>
Enable retrieval of the number of maximum clients connected to all sockets
combined, as well as the number of maximum clients waiting for authentication,
in order to be successfully connected. These are the attributes configurable
through libvirtd.conf, however, it could be handy to not only know values for
these limits, but also the values for the current number of clients
connected and number of clients currently waiting for authentication which are
changing dynamically. This API does both, retrieves the limits as well as the
current dynamic values.
