In this 6-video skill, CBT Nuggets trainer Garth Schulte covers the purpose and features of Microsoft Hyper-V. Gain an understanding of the App Compatibility feature in Windows Server 2019. Learn how to install and configure Hyper-V, how to create virtual machines by using graphical tools and PowerShell, and how to manage and monitor virtual machines and hosts. Watch this new Microsoft Windows Server training.
Networking, in particular, also can get hairy. Your CompTIA Network+ training will remind you that a well-built virtual environment will have several VLANs and subnets to segment out, running a management network for your physical hosts, and a storage network to communicate with shared storage, as well as multiple networks for your virtual servers as needed for security. If we remove the abstraction of VLANS, you have several physical ports on each server for each network, all of which have to be configured correctly on both the host and on the switch, or communication won't happen.
We mentioned VMware and Hyper-V earlier. Both are hypervisors, the software layer that actually abstracts your physical host's CPU, RAM, and storage to allow virtual machines to use those resources. While there are many flavors of hypervisors available, the two most popular are VMware's vSphere and Microsoft's Hyper-V.
Either way, CBT Nuggets has you covered for all your training needs. Microsoft covers Hyper-V thoroughly in its MCSA and MCSE server track certifications, and VMware's VCP-DCV certification is a deep dive into vSphere.
You got the skills, the platform, and the certs, so you're well on your way to becoming a virtualization pro. As you grow out your virtual infrastructure, the biggest key feature of your hypervisor to leverage will be high availability. This allows for automatic failover of virtual machines from one physical host to another when one goes offline.
Q: From a learner perspective, what did you keep in mind when creating this course?One of the objectives was to allow the learner to not only understand the concepts but to also get hands-on practice in our virtual labs, which will both reinforce the training and build the learner's skills as well.
While there aren't any prerequisite certs, knowledge of Cisco networking is expected. If you have your CCNA Routing and Switching (R&S) cert, then you're all set. If you don't, then you can get up to speed with our CCENT/CCNA 100-105 ICND1 and Cisco CCNA Routing and Switching 200-105 ICND2 training courses.
Beyond VMware, Microsoft, and Cisco, we're talking about players with small market shares in the virtualization space. In each case, these are products based on open source hypervisors like Xen and KVM. Certifications in this space may promise higher salaries, but that's probably because with fewer installations, job candidates may be thinner on the ground.
Our final "best of the rest" virtualization certification is the Red Hat Certified Specialist (RHCS) Virtualization. This cert is for SysAdmins who implement and manage virtual infrastructures that run on Red Hat Linux. Red Hat Virtualization is based on the KVM hypervisor that both AWS and Google use in their cloud services.
Although there are no formal prerequisites, you'd better be proficient in Linux administration. Ideally, you'd be a Red Hat Certified System Administrator (RHCSA). At a minimum, you should know the material covered in our Linux Foundation Certified Sysadmin training. The RHCS Virtualization exam (EX318) is a three-hour classroom exam that costs $400 USD.
In professional production environments, you're much more likely to encounter Type 1 virtualization. With Type 1 virtualization, a lightweight operating system known as a hypervisor is installed on a physical computer or server. The physical box is often called "bare metal" and Type 1 hypervisors are often called "bare metal hypervisors." Common examples of bare metal hypervisors are VMware's ESXi, KVM (Kernel-based Virtual Machine), and Microsoft's HyperV.
Once you install a bare metal hypervisor, you can then install multiple "traditional" operating systems on top of it. For example, with ESXi installed, you could run Windows Server 2016, CentOS 7.6, and Ubuntu 18.04 on the same hardware. ESXi provides virtual compute, storage, and memory to the operating systems.
Type 2 hypervisors, a.k.a. "hosted hypervisors," operate a bit differently. As opposed to being installed on top of bare metal hardware, they're installed on top of a standard operating system. Oracle's VirtualBox and VMware's VMware Player are popular examples of hosted hypervisors.
With a hosted hypervisor, you can run a second isolated operating system from within your main operating system. Suppose you want to run Linux Mint, but don't want to uninstall Windows from your PC or use dual boot. With a hosted hypervisor you can run an isolated instance of Linux Mint within your Windows PC.
Side note: For those familiar with Windows Server Operating Systems, describing HyperV as a Type 1 hypervisor may be confusing. It seems like HyperV runs on top of another operating system, which would make it a Type 2. However, when you get down to the nuts and bolts, HyperV runs beneath the operating system and accesses the hardware. The answers in this SuperUser post do a good job explaining the details.

While containers are generally used with *nix operating systems, they are available for Windows as well. If you're looking to dive into containers and Windows, check out our Implement Windows Containers training.
In this intermediate Microsoft Server 2016 training, Keith Barker, Anthony Sequeira, and Garth Schulte prepare learners to take the 70-740, 70-741, and 70-742 exams, which are the three exams required to earn the MCSA: Windows Server 2016 certification.
After completing this Microsoft training, you'll know how to use these new features as well as how to install Server 2016, manage Server 2016 software-defined networking products, and configure Active Directory Domain Services (AD DS). By completing this Server 2016 course, systems administrators will prove they're ready to advance into positions that lead to higher-level administrator roles and eventually systems engineer.
This Server 2016 training is considered associate-level Microsoft training, which means it was designed for systems administrators. This 70-740, 70-741, and 70-742 course is valuable for new IT professionals with at least a year of experience with Microsoft servers and experienced systems administrators looking to validate their Microsoft skills.
New or aspiring systems administrators. The MCSA from Microsoft is an entry-level certification and a great way to start an IT career. Since Microsoft products are ubiquitous in the market, our MCSA: Server 2016 training will make you a better candidate for sysadmin positions. Ideally suited for systems administrators with one year of experience, this exam can give your new career the boost needed for quick advancement.
Most hypervisors have something called dynamic memory, including Hyper-V. So, here's where life gets tricky. If you look under the Dynamic Memory area of the Hyper-V settings window, you'll notice a minimum and maximum setting. Hyper-V can adjust the amount of memory a VM uses in real-time. But, of course, things get muddy here.
For instance, if this VM is a mission-critical VM, you might want to give it a 30% buffer. That means the hypervisor will assign 8Gb of memory to the VM plus 30% just in case it needs it. That way, other greedy VMs don't come and take that valuable RAM space from our mission-critical virtual machine.
Finally, we have a setting for weight. This setting states where this VM falls in the pecking order. If the VM is super important, it gets a higher weight. That way, the hypervisor knows whom to service first. VMs with a lower weight are considered second-class citizens and only get resources after VMs with a higher weight are taken care of first.
So, learn how to implement Hyper-V the right way. Hyper-V is a fantastic tool that also happens to be free. It's included with Pro versions of Windows, Server versions of Windows, and as a standalone bare-metal hypervisor.
In fact, even at a very basic level, words such as hypervisor or virtual machine can be confusing. Are these the same thing? What runs on top of what? What is a type-1 or type-2 hypervisor? Fear not! We dive into the differences between the two and clear up the confusion.
For example, VMware, the market leader in virtualization, features its ESXi hypervisor platform. ESXi runs as a base operating system that can be installed onto a physical server. Once ESXi is running, an administrator can assign a network IP address to it, and then can proceed to manage it from a web interface or Java-based client. From the management interface, you also can provision virtual machines (also known as guests).
Virtual machines, therefore, can be defined as the servers that are created, installed, and run on top of a hypervisor. These virtual machines can be Windows servers, Linux servers, or any other supported OS type. All the resources that a virtual machine uses such as CPU and RAM are controlled and managed by the underlying hypervisor.
ESXi is known as a type-1 hypervisor, meaning that it gets installed directly onto a physical server. Type-2 hypervisors are different in that they get deployed on top of an already existing operating system.
So, If you want to enable the type-2 hypervisor that Microsoft offers, the Hyper-V feature can be added to this Windows 2012 server, enabling you to use the virtualization platform. After Hyper-V is enabled, a systems administrator can use the Windows-based tool Hyper-V Manager to create, install, and allocate virtual machines onto the Windows 2012 server running Hyper-V. Like VMware, Hyper-V supports virtual machines running Windows, Linux, (you read that correctly) and other supported OS platforms. 2b1af7f3a8
