Hi bob,

I don't agree with this view. If there's no XCP in Debian, I don't see
the point in supporting it in OpenStack. (and no, adding support for the
"magical" Citrix CentOS appliance blackbox isn't something I wish to do...)

Also, there's the need of python-xenapi in OpenStack, which was provided
by the xen-api sources. As I wrote, in Debian, I removed XCP support in
OpenStack (in fact, in Nova) a long time ago, because xen-api was
removed from testing, which therefore was blocking Nova to migrate to
testing. So even if I wanted to support something which isn't in Debian,
I wouldn't be able because of the lack of the XenAPI python module.

Again, I'm unhappy about this situation, and hope it can be solved. I
warmly welcome Citrix to work with me (again) to fix this quickly.

Cheers,
