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.
Independently of VMware, several startups also began to provide VM-aware storage products using existing virtual infrastructure management interfaces. These storage products are designed to support the same VM abstractions and allow storage management at the granularity of VMs. VMware announced its own vSphere storage appliance in 2011. [8]
Resolved an issue about shared folder when the user read and write file using two threads. Resolved an issue that caused Linux virtual machines to see stale file contents when using shared folders. Resolved the virtual machine performance issues when using the E1000e adapter. Resolved an issue preventing Workstation from starting on Ubuntu 14.04.
VMware's storage and availability products are composed of two primary offerings: VMware vSAN (previously called VMware Virtual SAN) is software-defined storage that is embedded in VMware's ESXi hypervisor. [149] [150] The vSphere and vSAN software runs on industry-standard x86 servers to form a hyper-converged infrastructure (or HCI).
Support for Windows 11 guest: UEFI Secure Boot and emulation of TPM 1.2 and 2.0 chips [26] Intel and AMD IOMMU emulation; Full VM encryption (in previous VirtualBox releases only VM disks could be encrypted) available via CLI [26] 3D acceleration with DirectX 11 on Windows, and DXVK on other hosts [26] Dark mode for UI currently implemented ...
User-mode Linux (UML) is a virtualization system for the Linux operating system based on an architectural port of the Linux kernel to its own system call interface, which enables multiple virtual Linux kernel-based operating systems (known as guests) to run as an application within a normal Linux system (known as the host).
VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware, a subsidiary of Broadcom, for deploying and serving virtual computers.As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel.
In theory, a virtual machine is a "completely isolated guest operating system installation within a normal host operating system", [2] but this isn't always the case in practice. 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.
