Top 10 Hypervisor Types Should Be Aware

Hyper-V (Hypervisor Technology) has been well received by some Microsoft critics and is made even more attractive with the release of a standalone version. Deb Shinder covers


Hypervisor technology is software that can run multiple virtual machines, where the hypervisor layer controls the hardware and allocates resources to individual VM operating systems. Hyper-V is a virtualization platform  included in Windows software server 2008. Microsoft recently also  released a standalone version2008. It can be downloaded for free  from Microsoft's website. As server virtualization becomes increasingly important  as a cost-cutting and security solution for enterprises and  Hyper-V becomes a major player in the virtualization space,  IT professionals can see how  technology works and what it can  do with it. It's important to understand what you can't do.


 This article describes 10 things you need to know about Hyper-V when considering deploying a virtualization solution in your network environment.

 

  • Host or Not  Host?

Hyper-V is a "type 1" or "native" hypervisor. This means that you have direct access to the hardware of the physical machine. This is different from Virtual Server 2005, which is a "type 2" or "hosted" virtualization product that must be run on the host operating system. B. Windows Server 2003 & # 41; You do not have direct access to the hardware.  The standalone version of HyperV is "bare metal". That is, it does not need to be installed on the underlying host operating system. This can be cheap. However, you lose the ability to perform additional server roles on the physical computer. Also, without a Windows Server 2008 host, there is no graphical interface. Standalone HyperV servers must be managed from the command line.


Standalone Hyper-V does not include support for high memory  (more than 32 GB of RAM) and  more than 4 processors available in the Enterprise and db Center editions of Windows Server 2008. You also cannot take advantage of the  high availability clustering and quick migration features included in the Enterprise and DataCenter editions.

 

  • System Requirements

Please note that HyperV Server 2008 is 64-bit software only  and can only be installed  on 64-bit hardware with Intel VT or AMDV Virtualization Acceleration Technology enabled. Supported processors include Intel's Pentium 4, Xeon,  Core 2 DUO, AMD's Opteron, Athlon 64, and Athlon X2.  DEP (Data Execution Prevention) must be activated (Intel XD bit or AMD NX bit). A processor of 2GHz or higher is recommended.

 

  • License requirements

Windows Server 2008 Standard Edition allows you to install  physical instances in devops online training and virtual machines of the operating system. The Enterprise Edition can run up to 4 VMs, and the DataCenter Edition license has no limit on the number of VMs.

 

  • File Format Compatibility

HyperV saves each virtual machine to a file with a .VHD extension. This is the same format used by Microsoft Virtual Server 2005 and Virtual PC 2003 and 2007.  VHD files created by Virtual Server and Virtual PC can be used with HyperV, but there are some differences in  virtual hardware (especially graphics cards). And network cards).

 

HyperV Management The HyperV Management Tool (MMC snap-in)


Vista allows you to  manage HyperV remotely from your Vista desktop. You must install SP1  before you can install and use the administration tools. You can download it to either 32-bit Vista or 64-bit Vista.

 

  • Emulated and Synthetic Devices

Users will not see this term in the user interface, but it is an important difference if you want to get the best  performance from your HyperV virtual machine as a best course for devops. Device emulation is a familiar way for virtualization software to handle hardware devices in Virtual Server and Virtual PC. The emulation software runs on the parent partition (the partition where you can call the hypervisor and request the creation of a new partition).

 

  • Integration component

After installing the operating system on the HyperV virtual machine, you need to install the integration component. This is a group of drivers and services that make synthetic devices available to guest operating systems. You can install it on Windows Server 2008 by Infrastructure as a Service (IaaS) selecting Insert Integration Services Installation Disc from the  HyperV Console Actions menu. Some operating systems require you  to go to your CD drive and manually install the components.

 

  • Virtual network

There are three types of virtual networks that can be created and used by the HyperV server. Private networks only allow communication between virtual machines. The internal network allows communication between the virtual machine and the physical machine (host or root operating system) on which Hyper-V is installed.

 

  • Virtual MAC address

If the VM on the same Hyper-V server has a duplicate MAC address, the second computer will not start because the MAC address is already in use. You will receive an error message informing you that  you are trying to access an invalid address.

`      

  • Using RDP with Hyper-V

When connecting to a Hyper-V server using Remote Desktop Connection, the mouse or pointing device may not be available within the guest operating system and keyboard input may not work properly prior to installation. Integrated service.

 

Conclusion

Hyper-V has also been well received by some experts who like anti-Microsoft trends. The release of the standalone version makes it even more attractive. IT professionals interested in the details can explore Microsoft learning resources in cloud computing online training related to HyperV technology, such as training and certification paths, on the Microsoft Virtualization Learning Portal.
