kolla-ansible xen fails with package.

[James]

Xen-hypervisor fails with a package not installing, package: python-os-xenapi should be changed to pip: os-xenapi. Also, xen doc could update noting a few dependencies that are necessary.

[Michal Nasiadka (mnasiadka)]

James - can you please add more insight to the bug, like is it caused by some backlevel version of python-os-xenapi package? On which distributions?

[Mark Goddard (mgoddard)]

Also, which images? Source/binary? Container OS? Host OS? Release of kolla/kolla-ansible?

What do you mean by the 'package not installing'? Here is part of the log you posted in IRC:

Given the python path, it looks like these are binary images. I can't see any explicit mention of os_xenapi package in the dockerfiles, so I assume it is pulled in via a package dependency, if at all.

For binary images we should not be installing packages via pip - only using the distro packages. If those packages need updating, that is an issue to bring up with the distro packagers.
