Hardware Virtual Machine (HVM) in Cloud Computing
Hardware Virtual Machine (HVM):
Dedicated software called hypervisor is used to make machines virtual to share resources. Hypervisors make multiple virtual hardware isolated from each other and create virtual machines that run various operating systems such as Unix, Linux or Windows operating systems on the same physical device. Virtualization reduces the need for physical machines and the maintenance cost of hardware, energy consumption and cooling consumption. Maintenance of virtual machines is effortless. Disaster recovery, backups or various administration tasks are also easy with virtual machines.
Hardware virtualization is a developing technology which can turn out to be foremost, particularly for server platforms. Virtual hardware behaviour comprises EFI and BIOS, accessible virtual PCI slots, the highest number of CPUs, the greatest memory design and other features typical to hardware. When you generate a virtual machine.
1. To register testing and instalment in a virtual environment.
2. If you do not require the facilities of the newer edition.
3. To maintain compatibility with previous hosts.
