We have an excepthook that logs uncaught exceptions for good
reason, but if printing --debug to stdout this exception gets
printed twice when we invoke the stock __excepthook__. Skip that
in the debug_stdout case.
Using these for long term TODO type items is not effective, however
it's nice to label things as FIXME during a coding session and have
pylint warn you about them before pushing.
This can help us find object leaks within the code. virConnectClose
is just a deference and will return 1 if other references are still
floating around.
Make check_support() accept a list of features.
This will let tests have more complex conditions on the features they
require.

Moves the libxml2 bits to a separate xmlapi file and class, a bunch
of cleanups to xmlbuilder internals dealing with XML stuff.
The main point is to experiment with different XML library impls,
since libxml2 is unfun to deal with and we are having python3
issues like
https://bugzilla.gnome.org/show_bug.cgi?id=776815
Currently the domain CPU class has a child property like:
siblings = XMLChildProperty(_CPUCellSibling)
If a user wants to add a new sibling, we add a convenience function:
def add_sibling(self):
obj = _CPUCellSibling(self.conn)
self.add_child(obj)
return obj
Rather than require every child property to define a similar matching
helper function, this adds infrastructure in xmlbuilder to do this
generically for every child property. Now callers can do
obj = guest.cpu.siblings.add_new()
In Python 2 the raise command can take 3 objects as arguments which
are used to specify the exception to be raise as well as detailed
information and traceback [1].
In Python 3 the sintax is changed and now the keyword "from" and
"with_traceback" keyworkds are used to specify this information. [2]
Example which has the same behaviour for both Python 2 and 3:
try:
a = 1/0
except Exception:
import sys
err = sys.exc_info()
try:
raise Exception("Test")
except:
pass
if sys.version_info[0] == 2:
exec("raise err[0], err[1], err[2]")
else:
raise
The `ipaddress` is available in Python 3.3+ [1] and backport for
Python 2 is available on PyPI [2].
The main differences between ipaddr and ipaddress are:
- ipaddress *Network classes are equivalent to the ipaddr *Network
class counterparts with the strict flag set to True.
- ipaddress *Interface classes are equivalent to the ipaddr *Network
class counterparts with the strict flag set to False.
- The factory functions in ipaddress were renamed to disambiguate them
from classes.
- A few attributes were renamed to disambiguate their purpose as well.
(eg. network -> network_address, numhosts -> num_addresses)
- A number of methods and functions which returned containers in ipaddr
now return iterators. This includes subnets, address_exclude,
summarize_address_range and collapse_address_list.
Another major difference is that in Python 2 the `ipaddress` module
must use unicode. [3]

Add vcpupin support to virt-install so that it can create guest
domains with statically allocated vcpu pinning towards a given cpuset.
Syntax: to pin vcpu=0 to cpuset="1,3" and vcpu=1 to cpuset=2
--cputune vcpupin0.vcpu=0,vcpupin0.cpuset=1,3,vcpupin1.vcpu=1,vcpupin1.cpuset=2
generates below XML description for the guest domain.
<cputune>
<vcpupin vcpu="0" cpuset="1,3"/>
<vcpupin vcpu="1" cpuset="2"/>
</cputune>
