The Crossbow project software, combined with next generation network interfaces like xge and bge, enable network virtualization and resource control for a single system. By combining VNICs with features such as exclusive IP zones or the Sun xVM hypervisor, system administrators can run applications on separate virtual machines to improve performance and provide security.
^ Exceptional for lightweight, paravirtualized, single-user VM/CMS interactive shell: largest customers run several thousand users on even single prior models. For multiprogramming OSes like Linux on IBM Z and z/OS that make heavy use of native supervisor state instructions, performance will vary depending on nature of workload but is near native.
The latter had been a separate software package in earlier history. By 2007 the term Solaris Containers came to mean a Solaris Zone combined with resource management controls. Later, there was a gradual move such that Solaris Containers specifically referred to non-global zones, with or without additional Resource Management.
SmartOS is a free and open-source SVR4 hypervisor based on the UNIX operating system that combines OpenSolaris technology with bhyve and KVM virtualization. [2] Its core kernel contributes to the illumos project. [3]
Oracle VM Server for x86 is a server virtualization offering from Oracle Corporation.Oracle VM Server for x86 incorporates the free and open-source Xen hypervisor technology, supports Windows, Linux, and Solaris [3] guests and includes an integrated Web based management console.
The Guest Additions for Windows, Linux, Solaris, OpenSolaris, and OS/2 guests include a special video-driver that increases video performance and includes additional features, such as automatically adjusting the guest resolution when resizing the VM window [38] and desktop composition via virtualized WDDM drivers.
The only operating system supported by the vendor for running within logical domains is Solaris 10 11/06 and later updates, and all Solaris 11 releases. There are operating systems that are not officially supported, but may still be capable of running within logical domains: Debian ports [12] version; OpenSolaris 2009.06; Illumos-derived releases
When multiple VMs are concurrently running on the hard drive of the actual host, adjunct virtual machines may exhibit a varying and/or unstable performance (speed of execution and malware protection). This depends on the data load imposed on the system by other VMs, unless the selected VM software provides temporal isolation among virtual machines.
