This example allows to use the guest agent event and metadata to track
vCPU count set via the guest agent (agent-based onlining/offlining) and
keep it persistent accross domain restarts.
The daemon listens for the agent lifecycle event, and if it's received
it looks into doman's metadata to see whether a desired count was set
and issues the guest agent command.

When called without parameters, sanitytest.py doesn't touch sys.path and
locates itself the patch to the libvirt-api.xml file using pkg-config.
This change makes possible to run sanitytest.py from tox.

Add support for the libvirt_virDomainGetIOThreadsInfo method. This
code mostly follows the libvirt_virDomainGetVcpuPinInfo method, but
also takes some from the libvirt_virNodeGetCPUMap method with respect
to building the cpumap into the returned tuple rather than two separate
tuples which vcpu pinning generates
Assuming two domains, one with IOThreads defined (eg, 'iothr-gst') and
one without ('noiothr-gst'), execute the following in an 'iothr.py' file:
import libvirt
con=libvirt.open("qemu:///system")
dom=con.lookupByName('iothr-gst')
print dom.ioThreadsInfo()
dom2=con.lookupByName('noiothr-gst')
print dom2.ioThreadsInfo()
$ python iothr.py
[(1, [False, False, True, False]), (2, [False, False, False, True]), (3, [True, True, True, True])]

The libvirt API has in the name "virDomain" but it's correctly mapped

In some cases, it is very easy for downstream distros to backport
enum values without requiring a .so bump. Keying the conditional
code off of the upstream version where the enum value was added
is not ideal, because downstream then has to patch that the feature
is available in their build that still reports an earlier version
number. For example, if RHEL 7 backports events from 1.2.11 into
a build based on 1.2.8, building the python bindings would warn:
libvirt-override.c: In function ‘libvirt_virConnectDomainEventRegisterAny’:
libvirt-override.c:6653:5: warning: enumeration value ‘VIR_DOMAIN_EVENT_ID_TUNABLE’ not handled in switch [-Wswitch]
switch ((virDomainEventID) eventID) {
^
libvirt-override.c:6653:5: warning: enumeration value ‘VIR_DOMAIN_EVENT_ID_AGENT_LIFECYCLE’ not handled in switch [-Wswitch]
The solution is simple - use feature-based probes instead of
version probes. Since we already scrape the XML API document of
whatever libvirt build we are binding, and that XML already
documents any downstream enum additions, we can use those as the
features for gating conditional compilation.
* generator.py (enum): Track event id names.
(buildStubs): Output define wrappers for events.
* libvirt-override.c

This returns the raw C pointer to the underlying object, eg:
conn = libvirt.open(None)
print "0x%x" % conn.c_pointer() # returns virConnectPtr of the connection
dom = conn.lookupByName("test")
print "0x%x" % dom.c_pointer() # returns virDomainPtr of the domain
The reason behind this is to allow us to transparently pass Python dom
objects through the libguestfs Python API.

When use blockCopy, flags cannot get a right value, because
PyArg_ParseTuple want to get 6 parameters and blockCopy only
pass 5. Flags will get a unpredictable value, this will make
the function fail with error:

When 'flags' is set to
'libvirt.VIR_CONNECT_GET_ALL_DOMAINS_STATS_ENFORCE_STATS,
python will report a error:
OverflowError: signed integer is greater than maximum
as VIR_CONNECT_GET_ALL_DOMAINS_STATS_ENFORCE_STATS is defined as 1<<31.
This happens as PyArg_ParseTuple's formatting string containing 'i' as a
modifier expects a signed integer.
With python >= 2.3, 'I' means unsigned int and 'i' means int so we
should use 'I' in the formatting string.

The override function was copied&pasted from virConnectGetAllDomainStats
and the function name after the colon was not changed. Fix the issue as
an invalid name would appear in the error message.
When give a nonzero flags to getTime, c_retval will get -1 and goto
cleanup. But py_retval still is NULL, so set py_retval = VIR_PY_NONE.
This will make the output message more correct.

Commit c58c7f362a fixed 32-bit python
build but broke build with python3 due to the lack of 'long' in the
newer version of python. This patch aims to fix it with a simple
string comparison of sys.version and '3'.

On 32-bit systems, one new flag that has the value of 1 << 31, namely
VIR_CONNECT_GET_ALL_DOMAINS_STATS_ENFORCE_STATS, fails to fit into an
'int' on python and is therefore of type 'long'. Fix sanitytest to
count with such fact in order to avoid build failures on 32-bit systems.

However that changed after the commit. So now we don't free any

The python documentation clearly advise us to call free() [2]. From
an example in their docs:
PyObject *res;
char *buf = (char *) malloc(BUFSIZ); /* for I/O */
if (buf == NULL)
return PyErr_NoMemory();
...Do some I/O operation involving buf...
res = PyString_FromString(buf);
free(buf); /* malloc'ed */
return res;
Moreover, instead of using VIR_FREE() (which we are not exporting),
I'll just go with bare free().
