Misconceptions about Hyper-V
Hyper-V has been always in demand from the day it entered into the market because of Virtualization technology base. Virtualization has prove itself to be a very effective element for the IT Business. As effective and useful as virtualization has proven to be for business IT, a number of Hyper V server virtualization myths are still in circulation, and widely believed by many IT pros.
There are always a thin line between the misconceptions and the confusion regarding any product, following are some of the misconceptions :
Basically the Windows Update Agent which reports that the updates are needed on a particular machine and not the “WSUS”. The WSUS console merely reports what it has been told. A seemingly trivial semantic point, but actually very critical in understanding the process so that failures can be accurately diagnosed. When the update is needed (i.e. Not Installed), does not mean that the Windows Update Agent can actually access that update in order to install it. The W U Agent reports status for *ALL* updates contained in the catalog of the WSUS Server, but the WSUS server, initially, only has the Update Definition, not the actual Update, so the Windows Update Agent is unable to download/install any updates just because the Update Definition exists on the WSUS server.
Generally people consider that Virtualization is only good for server consolidation. In some respects, virtualization has become a victim of its own success. Server consolidation via virtualization has saved many IT departments millions of dollars in hardware and power costs, but also contributes to the perception among some IT pros that virtualization is just a server-side solution.
There have been many aspects which has been considered before collaborating the the misconceptions. Another myth consists of that the VMware doesn’t take advantage of multi-core systems. It has been years since this myth is been circulating,and VMware’s Anderson indicates that the ESX Server family of products has been taking advantage of multi-core processors for a long time. While multi-core support in ESX server.
There can be many advantages too to be considered while people still have some little misconception regarding those as well like Virtualization is said to be a silver bullet. Virtualization can do wonders when it comes to increasing efficiency and power savings, but it can’t do it all. Some IT pros don’t research the downside of virtualization fully, which leads to the misconception that virtualization is a silver bullet that can solve all your IT problems. “Some believe it can take away all the pain, that it’s a magic pill,”
There has been a different approach towards the application scenario of virtualization like as Virtualization doesn’t work for high I/O applications. The conventional wisdom used to be that virtualization wouldn’t work well with apps that had high I/O demands. Anderson agrees that this may have been an issue in the early days of virtualization, but virtualization technology has made great strides in this area over the last five years.
Myths and misconceptions are the regular talk in the IT industry considering the fact that every product has pros and cons. There has been one major myth that to use VMware you need to know Linux. In the early days of VMware, several of VMware’s products required use of a Linux command line console to access some management functions. While that command line support is still available, most VMware customers will never need to touch a command line to perform management functions. “We have many Windows-based installations where administrators never have to use those command line features.
