OpenNebula just uses vCenter for live migration purposes. If this is the
usual configuration of VMware, then we can think about housekeeping the
vCenter. What do you use vCenter for?

We've taken the decision of not erasing the port groups because we thought
that it doesn't affect performance (but it imposes a penalty on the delete
operation). Do you know if keeping them there hinders performance? If so,
we will erase them.

Thanks a lot for your feedback! This is the useful stuff that helps
OpenNebula to grow.
