[Openstack-devel] Building nova with XenServer / XCP support

[Thomas Goirand]

Hi Julien, Ghe and Loic!

I've been working with Jon and Mike from Citrix on packaging XCP in SID
(project Kronos). This is done since this week (the last 2 of a series
of 8 packages got in), and seem to work fine. Now, I'd like to test nova
with it, and I'm having a hard time (it's not easy as well since there's
very few documentation and howtos about it).

Is there some build-dependencies that should be added to nova? I'm
asking because I see such warnings that some python modules aren't
present when building.

My understanding is that nova-compute-xen just remote controls Xen-API,
and as such, doesn't need to depend on the hypervisor (which is
currently the case in SID, and maybe in Ubuntu as well). So please
remove that dependency. I think it doesn't even need libvirt at all
either by the way (to be checked).

When I run the test suite, I get:

test_delete_key_pair ./run_tests.sh: line 73: 27322 Segmentation fault
${wrapper} $NOSETESTS 2> run_tests.log

Is that expected?

nova-api segfaults too when I start it:

Has any of you seen this before? Could it be an issue in
python-greenlet? I've seen this:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=650293

What version of python-greenlet do you currently run with successful
installs?

Cheers,
