Xen devel - Dec 2006 - [resend] [PATCH] [XS-TEST] Support for Xen-API authenticated session

I am adding a tool ''xapi-setup.py'' to the xm-test suite for
being able
to setup authentication credentials needed for automatically running
Xen-API - related tests. The username and password information is stored
in cleartext in lib/XmTestLib/xapi_auth.py.
In the one test using the Xen-API I add another check for availability
of the python PAM module. The test is skipped if the module is not
available on the system.

Ah, sorry, I''d forgotten about this one.

There is now a configuration file for xm (see
tools/examples/xm-config.xml) so would it make sense to pull the
username and password from there?  If you look at xen/xm/main.py,
there''s code for parsing the config file, and also for using the XenAPI
session manager and server proxy -- you ought to be able to import that
code now rather than using ServerProxy, and then there will be less for
xapi.py to do, because it will be sharing with xm.

Cheers,

Ewan.

I had not seen this file, but it seems not to be copied into /etc/xen/ by 
default. Would it be ok for now if I adapted the XML format and have 
xapi.py try to get username/password from the xm-config.xml file first and 
if it does not exist read the file created by the tool that I add to the 
xm test suite (xapi-setup.py) ?

No, it doesn''t go in by default at the moment, because it arrived quite
late
in the 3.0.4 run-up, so I decided not to activate it by default.  Sorry that
you''d missed it.  I''m going to change the Makefile in unstable
now so that it
gets put in there by default.

You could if you want to, but you''ll have a lot less code to write if
you just
import the relevant bits from xm:

~ # python
Python 2.4.4 (#2, Oct 19 2006, 23:03:48)
[GCC 4.1.2 20061007 (prerelease) (Debian 4.1.1-16)] on linux2
Type "help", "copyright", "credits" or
"license" for more information.
>>> import sys
>>> sys.path.append(''/usr/lib/python'')
>>> import xen.xm.main
>>> xen.xm.main.serverType
u''Xen-API''
>>> xen.xm.main.serverURI
u''http://localhost:9363/''
>>> xen.xm.main.parseAuthentication()
(u''ewan'', u''letmein'')


Connecting to the server should be a lot easier now too:
>>> from xen.xm import XenAPI
>>> session = XenAPI.Session(xen.xm.main.serverURI)
>>> session.login_with_password(*xen.xm.main.parseAuthentication())
>>> session.xenapi.VM.get_all()
[''00000000-0000-0000-0000-000000000000'',
 ''2f8dada9-387c-d981-0e51-6f5e2732d752'',
 ''53a01d42-c8c8-e561-6939-e2bc750454f7'']


It would be best, I think, if xm-test shares those bits of code with xm.

It''s possible that xm-test doesn''t need that code at all, in
the long run,
because it ought to be able to drive xm from the outside (that''s the
whole
point of xm-test after all -- its an end-to-end test).  What you seem to be
writing is tests for the API, but that don''t test xm itself. 
That''s great, if
xm itself will never have the bits of functionality under test.  The plan is
for xm to move over to using the new API throughout, so for the majority of
the functionality, we ought to be doing the full end-to-end test, and prodding
xm from the outside, rather than using ServerProxy.

Coverage from both aspects -- the raw API and the xm-sanitised version --
would be best, of course, but we''re already struggling to get enough
people
writing tests, so it''d be best to concentrate on the end-to-end tests
for now.

On my system I had quite a few problems when I copied the xm-config.xml 
file to /etc/xen. Probably you should change its contents so it does not 
use Xen-API by default, yet, since for example Fedora core installs
don''t
come with a pyhton PAM module - at least I could not find it and many 
others might not have installed the package, either.

The patch I sent before was due to me trying to create a VM using the 
Xen_API and the ramdisk not becoming available. So I think there is a need 
for testing the 
raw Xen-API as well. I wrote a basic test case for this and put it into a 
new directory tests/xapi into the xm-test suite.

Thanks. This is helpful for raw xen-api testing.

I understand, but functionality of xm will likely not cover the whole 
xen-api and so I think that separate tests for the raw xen-api can be 
useful.

Agreed.

The version I''ve just committed keeps the config settings at their
defaults,
yes.

For full authenticated access, you need Python-PAM, yes.  As an
alternative, you can now set your Xen-API server up to use no
authentication, with something like this in xend-config.sxp:

(xen-api-server ((127.0.0.1:9363 none)))

This will open TCP port 9363, listening only on the local interface, using no
authentication.

Certainly, I''d like to see tests that hit the raw API too. 
It''s still a
moving target, of course, but things are starting to settle down a bit,
so comprehensive test suites, either through the Python bindings, or
even the C bindings or the CIM providers would all be good.

Cheers,

Ewan.
