[2] 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).
[2] Since some users wanted backward compatibility with NetWare, Novell offered two installation options: OES-NetWare and OES-Linux.
[4] 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.
It was the first SLES-Linux-kernel-only OES, but it retained the OES-NetWare operating system option, as NetWare 6.5 SP7 can run as a paravirtualized guest inside the Xen hypervisor.
[10] Breaking with previous convention, OES 23.4 (rather than SP1) was released in October 2023, and was rebranded to OpenText,[11] after their purchase of Micro Focus earlier in the year.
