Introduces support for virDomainSetMemory. This also serves an an
example for how to use the new method invocation API with a more
complicated method, this time including an EPR and embedded param.
This commit adds support for virDomainSendKey. It also serves as an
example of how to use the new method invocation APIs with a single
"simple" type parameter.
Update the generator to generate basic property type information for
each CIM object representation. Right now, it generates arrays of
hypervCimType structs:
struct _hypervCimType {
const char *name;
const char *type;
bool isArray;
};
This commit introduces functionality for creating and working with
invoke parameters. This commit does not include any code for serializing
and actually performing the method invocations; it merely defines the
functions and API for using invocation parameters in driver code.
HYPERV_DEFAULT_PARAM_COUNT was chosen because almost no method
invocations have more than 4 parameters.
Functions added:
* hypervInitInvokeParamsList
* hypervFreeInvokeParams
* hypervAddSimpleParam
* hypervAddEprParam
* hypervCreateEmbeddedParam
* hypervSetEmbeddedProperty
* hypervAddEmbeddedParam
* hypervFreeEmbeddedParam

Convert HAVE_DBUS to WITH_DBUS

The default conf files, for example libvirtd.conf, virtlockd.conf, and
virtlogd.conf, should be located under the directory "/etc/libvirt" when

When one has a non-blocking stream and aborts or finishes it without
removing the callback, any event loop invocation will trigger that
callback, but it cannot be removed any more. We cannot remove the
callback automatically from virStream{Abort,Finish} functions due to
forward-compatibility. So let's at least document this behaviour,
because it is not easy to find out the reason for.

Add support for vgaconf driver configuration. In domain xml it looks like
this:
<video>
<driver vgaconf='io|on|off'>
<model .../>
</video>
It was added with bhyve gop video in mind to allow users control how the
video device is exposed to the guest, specifically, how VGA I/O is
handled.
One can refer to the bhyve manual page to get more detailed description
of the possible VGA configuration options:
https://www.freebsd.org/cgi/man.cgi?query=bhyve&manpath=FreeBSD+12-current
The relevant part could be found using the 'vgaconf' keyword.
Also, add some tests for this new feature.

Despite being a generated file, HACKING has been tracked in
the git repository along with actual source files. As far as
I'm aware, it's the only generated file for which that happens.
Times and times again, people[1] have committed changes to
the source file without refreshing the generated copy at the
same time.
The rationale for tracking the generated file is to help out
people who just cloned the git repository looking to contribue;
however, README-hacking already contains enough information to
get perspective contributors to a place where they can simply
look at docs/hacking.html instead.

If a remote call fails during event registration (more than likely from
a network failure or remote libvirtd restart timed just right), then when
calling the virObjectEventStateDeregisterID we don't want to call the
registered @freecb function because that breaks our contract that we
would only call it after succesfully returning. If the @freecb routine
were called, it could result in a double free from properly coded
applications that free their opaque data on failure to register, as seen
in the following details:
Program terminated with signal 6, Aborted.
#0 0x00007fc45cba15d7 in raise
#1 0x00007fc45cba2cc8 in abort
#2 0x00007fc45cbe12f7 in __libc_message

The double dereference of 'pyobj_cbData' is triggered in the following way:
(1) libvirt_virConnectDomainEventRegisterAny is invoked.
(2) the event is successfully added to the event callback list
(virDomainEventStateRegisterClient in
remoteConnectDomainEventRegisterAny returns 1 which means ok).
(3) when function remoteConnectDomainEventRegisterAny is hit,
network connection disconnected coincidently (or libvirtd is
restarted) in the context of function 'call' then the connection
is lost and the function 'call' failed, the branch
virObjectEventStateDeregisterID is therefore taken.
(4) 'pyobj_conn' is dereferenced the 1st time in
libvirt_virConnectDomainEventFreeFunc.
(5) 'pyobj_cbData' (refered to pyobj_conn) is dereferenced the
2nd time in libvirt_virConnectDomainEventRegisterAny.
(6) the double free error is triggered.
Resolve this by adding a @doFreeCb boolean in order to avoid calling the
freeCb in virObjectEventStateDeregisterID for any remote call failure in
a remoteConnect*EventRegister* API. For remoteConnect*EventDeregister* calls,
the passed value would be true indicating they should run the freecb if it
exists; whereas, it's false for the remote call failure path.
Patch based on the investigation and initial patch posted by

The function to check if -chardev is supported by QEMU was written a
long time ago, where adding chardevs did not make sense on the fixed ARM
platforms. Since then, we now have a general purpose virt platform,
which should support plugging in any device over PCIe which is supported
in a similar fashion on x86.

As it turns out the volume create, build, and refresh path was not peeking
at the meta data, so immediately after a create operation the value displayed
for capacity was still incorrect. However, if a pool refresh was done the
correct value was fetched as a result of a meta data peek.
The reason is it seems historically if the file type is RAW then peeking
at the file just took the physical value for the capacity. However, since
we know if it's an encrypted file, then peeking at the meta data will be
required in order to get a true capacity value.
So check for encryption in the source and if present, use the meta data
in order to fill in the capacity value and set the payload_offset.
Similarly to commit 5da28cc306 this check
actually does not make sense since duplicate WWNs are used e.g. when
multipathing disks.
This reverts commit 780fe4e4ba.

When fetching stats for a vhost-user type of interface, we run
couple of ovs-vsctl commands and parse their output. However, not
all stats exist at all times, for instance "rx_dropped" or
"tx_errors" can be missing. Thing is, we ask for a bulk of
statistics and if one of them is missing an error is reported
instead of returning the rest. Since we ignore errors, we fail to
set statistics. Fix this by asking for each piece alone.
