Q13. Explain About Virtual Machine Architecture?

Virtual Server

The virtual system sessions running in Microsoft Virtual Server are applied as a hard and fast of COM gadgets which might be available through the Virtual Server COM API. The digital machine classes are isolated from every different and may be viewed as absolutely separate hardware environments.

A new virtual system session is initialized whilst an IVMVirtualMachine item is created the usage of VMVirtualServer::CreateVirtualMachine. The IVMVirtualMachine item carries a standardized set of emulated hardware, apart from any virtual hard disks or networks which need to be created separately and then attached to the IVMVirtualMachine item. A digital gadget session is the equal of a bodily hardware machine and have to be regarded as a separate computer in regards to troubles concerning running system and application software installation and licensing.

The operating kingdom of a virtual device session is managed via the IVMVirtualMachine's Startup, TurnOff, Reset, Save, Pause, and Resume methods. Access to the virtual device's emulated hardware is through the various assets values of the IVMVirtualMachine item, which include either characteristic values of the virtual gadget or suggestions to other COM gadgets which put in force the numerous emulated hardware gadgets consisting of serial ports, network cards, and so forth.

There isn't any get admission to to a digital system's running machine or application software unless the Virtual Machine Additions software module is installed in the virtual system consultation. Installing Additions enables most of the techniques and homes of the IVMGuestOS object associated with the virtual gadget consultation. IVMGuestOS lets in Virtual Server to execute software applications in the virtual machine session, carry out an orderly Shutdown of the virtual device's working system, and to generate a regular "tick" or "heartbeat" occasion which allows Virtual Server to reveal the working country of the digital system.

Q14. What Is The Process Of Creating A Virtual Network?

To create a virtual community virtual machines are required that must be configured for the accessing.

Virtual community is supported by using virtual server to attach many virtual machines that may be shared with many computer systems within the community.

Virtual community require community adapter to be configured and hooked up to a physical computer, this manner any pc can get entry to the resources from every other computer.

Virtual server makes use of DHCP server to dynamically assign the IP address to the computer systems in an effort to connect with other systems. Virtual server in this case has digital DHCP that lets in system to be uniquely identified. 

Multiple Virtual community can be configured on a single network adapter by way of growing and associating the virtual community with a network adapter. After the stairs digital machines may be added to the virtual community of host working gadget.
 

Q15. Can You Explain What Are The Benefits Involved In Virtual Server Host Clustering?

The benefits which might be concerned in digital server host clustering are as follows:

Server consolidation: permit virtual servers to consolidate more than one servers into one on the way to be clean to track and keep digital machines at one server together.

Increased availability: virtual server host clustering will increase the supply of consolidated server because of which if any failure happens then any other server can soak up the activity this is being served with the aid of the primary server.
