Unlike NetWare, Novell OES is a [[Linux distribution]]—specifically, one based on [[SUSE Linux Enterprise Server]]. <ref>{{Cite web |last=Rouse |first=Margaret |date=December 21, 2011 |title=Open Enterprise Server |url=https://www.techopedia.com/definition/26069/open-enterprise-server-oes |url-status=live |archive-url=https://web.archive.org/web/20230810085220/https://www.techopedia.com/definition/26069/open-enterprise-server-oes |archive-date=August 10, 2023 |access-date=October 31, 2023 |website=Techopedia}}</ref>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 (operating system)|kernel]] (with a [[Linux]] compatibility layer).<ref name="Morgan" /> Novell discontinued the NetWare kernel prior to the release of OES 2, but NetWare 6.5 SP7, and later SP8 can run as a [[Paravirtualization|paravirtualized]] [[Hardware virtualization#Paravirtualization|guest]] inside the [[Xen]] [[hypervisor]] (Officially supported until 7 March 2012, Novell self-supported until 7 March 2015).

=={{anchor|1.01|2.03}}OES 1 and OES 2 ==

Novell released OES 1, the first version of OES, on 25 March 2005.<ref name="Morgan" /> Since some users wanted [[backward compatibility]] with NetWare, Novell offered two installation options: OES-NetWare and OES-Linux. These are two different operating systems with different kernels and different [[User space#Overview|userlands]].

OES-NetWare is NetWare v6.5 equipped with [[NetWare Loadable Module]]s for various Novell services (such as [[NetWare Core Protocol]], [[Novell eDirectory]], [[Novell Storage Services]], and [[iPrint]]) and [[open-source software]] (such as [[OpenSSH]], [[Apache Tomcat]], and the [[Apache HTTP Server]]).<ref>{{Cite web |last=Hewlett Packard Enterprise |date=October 21, 2005 |title=Open Enterprise Server (OES) |url=https://www.hpe.com/psnow/doc/c04283233 |url-status=live |archive-url=https://web.archive.org/web/20220717064800/https://www.hpe.com/psnow/doc/c04283233.html |archive-date=July 15, 2022 |access-date=October 31, 2023 |website=Hewlett Packard Enterprise |type=Imbedded PDF |format=PDF}}</ref>

OES-Linux is based on the [[SUSE Linux Enterprise Server]] (SLES) with added NetWare services ported to the Linux kernel: e.g. the NetWare Core Protocol, Novell eDirectory, Novell Storage Services, and iPrint.
