Virtualization software for Linux

Server virtualization – emulation of server resources that includes individual physical servers, processors, and operating systems.

It is very important for a virtualization server nowaday as you do not need to worry about the physical server hardware problem.

Today I want to discuss the Virtualization software type of Linux OS,

is a hypervisor that supports x86-64, Itanium, PowerPC 970, and IA-32 architectures. It can run a number of guest operating systems on a single computer hardware simultaneously. Xen utilizes a form of virtualization known as paravirtualization, which means guests run a modified operating system using a special hypercall ABI in place of specific architectural features. Because of this, Xen can achieve high performance even on x86 host architecture that is known to have an issue with traditional virtualization procedures.

Based on the Linux kernel and operating system, OpenVZ is an operating system-level virtualization technology. OpenVZ features a physical server than runs multiple isolated operating system instances, known as containers, Virtual Private Servers (VPSs), or Virtual Environments (VEs). Every container is an isolated entity, and functions extensively as a physical server would.

VirtualBox supported guest OS are BSDs, OS/2 Warp, Windows, Solaris, Haiku, Syllable, ReactOS and SkyOS. VirtualBox supports hardware virtualization for both the Intel VT-x and the AMD AMD-V extensions. Hard disks are emulated in one of three disk image formats: VirtualBox Virtual Disk Image (VDI); VMware Virtual Machine Disk Format (VMDK); and Microsoft Virtual PC VHD format. This means that a VirtualBox virtual machine can use disks that were created in VMware or Microsoft Virtual PC aside from its own native disk format.
