It was first published by Novell in March 2005 to succeed their NetWare product. Unlike NetWare, OES is a Linux distribution—specifically, one based on SUSE Linux Enterprise Server. The first major release of Open Enterprise Server (OES 1) could run either with a Linux kernel (with a NetWare compatibility layer) or Novell's NetWare kernel (with a Linux compatibility layer). Novell discontinued the NetWare kernel prior to the release of OES 2, but NetWare 6.5 SP7, and later SP8, can run as a paravirtualized guest inside the Xen hypervisor (officially supported until 7 March 2012, Novell self-supported until 7 March 2015). OES 1 and OES 2 Novell released OES 1, the first version of OES, on 25 March 2005. Since
