Konsep Virtualisasi

Jenis Aplikasi Populer Virtualisasi VMware KVM Xen

VMwareOnly available version 5.5 workstation for

LinuxMax Performance in MS Windows

Enviroment Very popular VM

KVM Support build in Kernel Linux Fully Open Source Easy of installation and configuration

using Proxmox

XenMemiliki Teknologi PV (Paravirtualization)

dan HVM (Hardware Virtual Machine) Has a free and paid version (Citrix

XenServer) Amazon, AMD, Cisco, Citrix, Intel, Oracle,

Samsung, and Verizon Use it.

Arsitektur Xen

Komponen Xen The Xen HypervisorGuest Domains/Virtual Machines The Control Domain (or Domain 0) Toolstack and Console: Domain 0 Xen-enabled operating systems

Xen PV Advantages Runs a full unmodified OS, excluding

bootloader + kernel Can compile and load your own kernel

modules Highly scalable, low overheads Easy OS reloads with precreated templates Direct allocations of RAM + HDD, not oversold

and cannot be used by other VPS Easily upgraded/downgraded or migrated to

another host machine if required

Xen PV Disadvantages Supports Linux only Limited to only the precreated OS

templatesCan't modify the OS options during installCan't compile and install a custom kernel

unless using Pygrub Fixed two filesystem layout with two

partitions, one for hdd one for swap

Xen HVM AdvantagesComplete and secure isolation Run Linux, Unix, BSD or WindowsCustomize your kernel, and even your

partition layouts Behaves exactly like a real physical server Large ISO library updated reguraly

Xen HVM Disadvantages Slower / more time comsuming re-installs Higher overheads than Xen PVMore dificult to upgrade/downgrade or

migrate to another host machine if required
