OpenStack has great support for XenServer (and XCP), but one of the stumbling blocks has been the lack of documentation in some crucial areas.
Over recent weeks we have made some great improvements to the documentation. Please take a look, but do let us know your ideas on where you would like us to focus our next efforts: http://docs.openstack.org/
For a closer look at what we have planned, take a look at the bugs we have raised: http://bugs.launchpad.net/openstack-manuals
Today was my first day, joining with other members of the Xen development community, to dedicate one day a month to improving documentation. My plan, over the coming months, is to continue to take part in the Xen community’s drive to improve their documentation, focusing on where we can improve documentation around OpenStack.
