    OpenStack has recently released Folsom.

  6. Citrix OpenStack Team take part in Xen Document Day

    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.
