VMware VMFS (Virtual Machine File System) is VMware, Inc.'s clustered file system used by the company's flagship server virtualization suite, vSphere. It was developed to store virtual machine disk images, including snapshots. Multiple servers can read/write the same filesystem simultaneously while individual virtual machine files are locked.
vCenter Server Appliance (VCSA) is the centralized management utility for VMware, and is used to manage virtual machines, multiple ESXi hosts, and all dependent components from a single centralized location. VMware vMotion and svMotion require the use of vCenter and ESXi hosts.
Some other products such as VMware and Virtual PC use similar approaches to Bochs and QEMU, however they use a number of advanced techniques to shortcut most of the calls directly to the CPU (similar to the process that JIT compiler uses) to bring the speed to near native in most cases.
VirtualBox emulates hard disks in three formats: the native VDI (Virtual Disk Image), [36] VMware's VMDK, and Microsoft's VHD. It thus supports disks created by other hypervisor software. VirtualBox can also connect to iSCSI targets and to raw partitions on the host, using either as virtual hard disks.
In computing, a virtual machine (VM) is the virtualization or emulation of a computer system.Virtual machines are based on computer architectures and provide the functionality of a physical computer.
GPU virtualization refers to technologies that allow the use of a GPU to accelerate graphics or GPGPU applications running on a virtual machine.GPU virtualization is used in various applications such as desktop virtualization, [1] cloud gaming [2] and computational science (e.g. hydrodynamics simulations).
Open Virtualization Format (OVF) is an open standard for packaging and distributing virtual appliances or, more generally, software to be run in virtual machines.. The standard describes an "open, secure, portable, efficient and extensible format for the packaging and distribution of software to be run in virtual machines".
For example, in 2008, a vulnerability (CVE-2008-0923) in VMware discovered by Core Security Technologies made VM escape possible on VMware Workstation 6.0.2 and 5.5.4. [3] [4] A fully working exploit labeled Cloudburst was developed by Immunity Inc. for Immunity CANVAS (a commercial penetration testing tool). [5]
