Operating system Solaris
Type Virtual machine monitor

Sun xVM is a product group from Sun Microsystems that addresses virtualization technology on x86 platforms.[1]


Sun originally announced the xVM product family in October 2007 as a broader product line. The brand at one time encompassed Sun xVM Server, Sun xVM Ops Center, and Sun xVM VirtualBox,[2] but the latter two products no longer use "xVM" branding.[1]


Sun xVM hypervisor

The Sun xVM hypervisor is a component of the Solaris Operating System based on the work that was being done in the OpenSolaris Xen community.[1] It was integrated into the OpenSolaris source base, and was available in OpenSolaris OS distributions. It provided the standard features of a Xen-based hypervisor on x86-based systems.[3]

Sun xVM Server

Sun xVM Server is based on the xVM hypervisor project. Sun plans to support Microsoft Windows, Linux, and Solaris as guest operating systems.

Various features from Sun's OpenSolaris OS underlie the guest OS as part of the hypervisor environment, including Predictive Self Healing, ZFS, DTrace, advanced network bandwidth management (from the OpenSolaris Crossbow project) as well as security enhancements.[4]

Instead of having its own disk image format, Sun xVM Server will import/export VMDK [5] and VHD images to facilitate interoperation with VMware ESX Server and Microsoft's Hyper-V.

In early May 2009, the Xen community at 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.
