Answer these 3 questions....
Assuming that the IT operations of your organization were a heterogeneous environment which included a variety of operating systems, what might be some potential limitations of using Hyper-V as a virtualization platform? Is there a way to create a Hyper-V virtual machine other than using the New Virtual Machine Wizard? If so, what is it? Look through the settings options for one of your virtual machines. What options does Hyper-V provide for overprovisioning resources on the Hyper-V host or dynamically allocating additional resources to the guest VM on demand?Explanation / Answer
Answer to question 9:
There are a lot of potential limitations of using Hyper-V over other virtualization platforms. Following are the reasons:
1) Unlike VMware, Microsoft's main business is not virtualiztion or any other technology but it's all about selling operating system licenses. Hence the main Hyper-V disadvantage is that Microsoft owns Hyper-v and microsoft wants to sell operating systems, not virtualiztion technology per se. When you start using hyper-v, you are indirectly agreeing to buy operating systems in not so distant future.
2) Some people actually speculate that the only reason why microsoft jumped into virtualiztion was to sell more windows servers. While it is correct that hyper-v server is a free operating system, when you read the terms and conditions and a have look at what the license permits and what not, and what features are not part of hyper-v server, but requires a windows server instead, you realize its an entry path to purchasing a windoes server
3) Another major disadvantage is that the graphical user interface is missing. As you dig deeper you you realise in order to run a bigger virtual platform you need a domain controller and lots of other things, so you are quickly adding up costs.
4) While hyper-v is in fact the best choice for many businesses, some businesses fall into a trap without knowing what's ahead. Here are some scenarios:
a)You spend a lot of time figuring out how to use hyper-v server because its free and because everyone is doing it. You give it up because it doesnt have a user interface, or you discovered some other missing parts and decide to switch to a windows server.
b) Hyper-v and windows server is being upgraded all the time.So you suddenly find out it no longer supports some operating systems. So you need to upgrade VM's just because microsoft wants you to do so.
c) A new Windows version comes out. The older Hyper-v wont let you do certain things with the newer VM OS. Hence you need to upgrade your Hper-v. Once you do that, the newer hper-v no longer supports the older VM OSes you have got.
5) Hyper-V(2012 R2) supports a limited number of guest OS choices. Some of them are Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows Server 2003 SP2, etc
6) Another disadvantage is poor or missng support for RemoteFX and Service Templates in System Center Virtual Machine Manager 2012 R2.
7) Some of the design disadvantages of hyper-v are follows:
a) Controlling Layer requires an installed OS before hyper-v can operate.
b) If controlling layer OS crashes, all VM's crash
c) Controlling layer requires more overhead.
d) Security depends on the application of Microsoft security updates, which requires all VMS to be taken offline or moved to a different node to avoid downtime.
8) Another disadvantage is hyper-v doesnt support live migration of VMs between servers and doent allow administrators to over-commit memory which is provided by VMware
There is nothing legally wrong with all of the above, its just that by the time most people find out whats going on and how it translates to future costs, they have already heavily invested into Microsoft technologies, in terms of time and labor as well as money.
