Sun xVM was a product line fromSun Microsystems that addressed virtualization technology onx86 platforms.[1] One component was discontinued before theOracle acquisition of Sun; the remaining two continue under Oracle branding.
Sun originally announced the xVM product family in October 2007. The brand at one time encompassedSun xVM Server,Sun xVM Ops Center, andSun xVM VirtualBox,[2] but the latter two products abandoned the "xVM" branding in late 2009, and are now calledOracle Enterprise Manager Ops Center andOracle VM VirtualBox.[1]
TheSun xVM hypervisor was a component ofSolaris based on work that was being done in theOpenSolarisXen community.[1] It was integrated into the OpenSolaris source base, and was available in OpenSolaris OS distributions, providing the standard features of a Xen-based hypervisor onx86-based systems.[3]
Sun xVM Server was based on the xVM hypervisor project. Sun planned to supportMicrosoft Windows,Linux, andSolaris as guestoperating systems.
Various features from Sun'sOpenSolaris OS underlay the guest OS as part of the hypervisor environment, including Predictive Self Healing,ZFS,DTrace, advanced network bandwidth management (from the OpenSolarisCrossbow project) as well as security enhancements.[4]
Instead of having its own disk image format, Sun xVM Server was intended to import/exportVMDK andVHD images to facilitate interoperation withVMware ESX Server and Microsoft'sHyper-V.[5]
In early May 2009, theXen community at OpenSolaris.org announced that separate xVM Server development would be discontinued as such, with the Xen/OpenSolaris project filling its role and the team that previously worked on xVM Server refocusing on Ops Center as the principal means of managing multiple hypervisors on multiple physical machines from a single point of control.[citation needed] Sun VP Steve Wilson said that xVM hypervisor support would not be part of commercial Solaris.[6]
