Comment 5 for bug 1471934

LaTeX is running during the docs build because of the .. math:: directives in the hyperv code here:

https://github.com/openstack/nova/blob/master/nova/virt/hyperv/vhdutilsv2.py#L129

That's built through the sphinx.ext.pngmath extension here:

https://github.com/openstack/nova/blob/master/doc/source/conf.py#L33

But to build that stuff, you need latex and some other package for the utf8x.def file:

debs:

texlive (for latex)
texlive-latex-extra (for utf8x.def)

rpms:

texlive (for latex)
texlive-latex (for utf8x.def)

Alternatively we could just not support math in the docstrings and update the hyper-v module. I doubt that latex is on the nodes that build the nova-python-docs job, so that would be a dependent update to the job config in project-config if they aren't there.
