Hyper-V virtual service Overview (1)

Virtualization Technology Hyeper-V) is a very important technology currently. It can run multiple virtual machines on one physical machine. The functions of virtual machines are the same as those of physical machines. The Windows Server 2008 R2 operating system supports virtualization, known as the Hyper-V service, "virtual service technology ". The operating systems used by physical computers and virtual machines running Hyper-V services are uniformly on the underlying Hypervisor.

Hyper-V Overview

Hyper-V is an underlying virtual machine program that allows multiple operating systems to share one hardware. It is located between the operating system and the hardware and is a thin software layer, it does not contain the underlying hardware driver. Hyper-V directly takes over VM management and divides system resources into multiple partitions. The partition where the primary operating system is located is called the parent partition, And the partition where the virtual machine is located is called the subpartition.

Features of Hyper-V

In Windows Server 2008, Hyper-V only adds one role, which is identical to the DNS, DHCP, and IIS roles. Hyper-VZ adds a Hyper-V layer between the operating system and the hardware layer. Hyper-V is a virtual machine technology based on Hyper-V.

Main features of Hyper-V:

1. virtual machines based on the 64-bit System Computer Virtual Machine Management Program.

2. It can run both 32-bit and 64-bit virtual machines.

3. Single-processor and multi-processor virtual machines.

4. VM snapshots capture the status of the running Vm and record the system status so that the VM can be restored to the previous status.

5. Large VM memory is supported.

6. Support for Virtual LAN.

7. Microsoft Management Console MMC) 3.0 management tool.

Hyper-V system requirements

Basic hardware requirements for installing Windows Server 2008 Hyper-V

1. The cpu must be at least 1 GHz. 2 GHz and faster CPU is recommended.

2. The minimum memory is 512 MB. 1 GB is recommended. 2 GB memory is recommended for Windows Server 2008 installation.

3. Install the 64-bit Standard Edition, which supports up to 32 GB memory.

4. Disk: Windows Server 2008 is fully installed. 40 GB disk space is recommended.

Hyper-V has high hardware support and focuses on the CPU:

1. The CPU must support Virtualization of hardware, such as Interl VT technology, AMD-V technology.

2. the CPU must support X64 bit technology.

3. The CPU must support the hardware DEP technology, that is, the CPU anti-virus technology.

4. The hardware virtualization function must be enabled for BIOS settings of the system. By default, the virtualization function of the CPU is disabled.

5. Windows Server 2008 must use X64. X86 does not support virtualization.

To understand the above overview, we can install Hyper-V below.
