What Is Virtualization?

Virtualization can be an efficient and cost-effective solution to installing or running two operating systems on the same hardware, or troubleshooting problems with an application.

Liquid Web offers several Ubuntu server hosting plans. In this blog post, we’ll outline three techniques for setting up an Ubuntu server as a virtual machine (VM) host.

What is a virtual machine?

Virtual machines (VM) are software environments that function just like physical computers in many ways, from running applications and operating systems to viewing files, watching videos and connecting to the internet. A VM runs independently from its host computer so as not to utilize any processor, memory or storage resources that might otherwise be allocated by its host; by using VMs for these purposes you can reduce hardware costs while decreasing data center operating expenses; additionally they offer powerful security as if one VM becomes compromised it won’t impact other VMs running on it as much.

An physical server equipped with virtualization software such as Microsoft Hyper-V, Citrix XenServer or VMware vSphere can host numerous virtual environments thanks to virtualization software such as Hypervisor. A software layer called hypervisor allocates computing resources directly from its host machine into pools for guest virtual machines (VM). This ensures an end-user experience nearly identical to having your OS running directly on it.

As well as supporting third-party hypervisors, the Linux kernel also features its own virtualization module called KVM that offers a fast and efficient method for creating virtual machines without additional software installation. KVM utilizes minimal system resources when starting quickly – an excellent choice for isolating application environments.

Containers are another popular virtualization technology, being lightweight and requiring less resources than full VMs. Common uses for them include packaging and deploying applications; their creation on any platform doesn’t require an operating system installation and their provisioning can happen much more rapidly than traditional virtualization solutions.

Before choosing to utilize virtual machines (VMs), it’s important to consider both their benefits and drawbacks. Common advantages may include reduced hardware costs as VMs share one physical machine instead of multiple components; increased flexibility and scalability as they can easily be moved or copied between servers; enhanced security as they are completely separate from each other and independent from host system reliance; which may help boost performance.

Types of virtual machines

There are various kinds of virtual machines. Each offers unique benefits and uses, yet all virtual machines provide the same core functionality:

Virtual machines (VMs) can be an invaluable resource for testing software, creating multiple operating system environments, backing up data and performing other important tasks. They can be hosted both on-premises and in the cloud; and when best practices such as encryption, access controls and hypervisor patching are implemented for security they tend to remain highly reliable.

System and process virtual machines (VMs) are two primary types of virtual machines. System VMs emulate an entire physical environment and are usually employed for server consolidation and software testing purposes, as well as running multiple OS environments on one physical computer. Process VMs emulate individual processes in software.

Process virtual machines (VMs), on the other hand, only run one operating system or application at any one time – they’re typically used for cross-platform application execution and development, or testing patches or studying security vulnerabilities without placing their host operating system at undue risk.

Setting up a virtual machine on Ubuntu requires several different tools and approaches. The most straightforward option is using virt-manager, an easy-to-use interface for managing virtual machines. Or alternatively, use virt-install, part of the virtinst package, for a command line approach – to create one just type in “virt-install –name web_devel –ram 8192” into terminal window to create new virtual machine instance.

Virtual machines (VMs) are completely isolated from each other and the host computer, enabling them to be shut down or restarted easily without disrupting other VMs or the host OS. Furthermore, they can be quickly backed up and restored when disaster strikes; making VMs ideal for disaster recovery purposes. VMs are also highly flexible; you can configure them to meet specific business needs; such as automatically restarting when physical hardware fails or being deployed across an ecosystem for rigorous testing – this flexibility makes VMs perfect for modern computing!

KVM hypervisor

KVM (Kernel-based Virtual Machine) is an open source hypervisor that is capable of turning physical Linux servers into hosts capable of hosting multiple virtual machines independently. KVM utilizes hardware virtualization extensions like Intel VT-x and AMD-V to provide optimal performance and efficiency, as well as advanced memory management, scheduling, and I/O handling to maximize processing space and memory usage efficiency – making it highly scalable solution suitable for both small and large enterprise systems alike.

KVM also supports network namespaces and control groups, which serve to limit applications’ capabilities while isolating resource use from different processes on a system. This feature ensures that when one VM fails, its failure does not impact other virtual machines on that same machine, while simultaneously decreasing performance overhead while increasing security by restricting access to critical system resources.

KVM has many benefits that make it an appealing virtualization choice in the Linux ecosystem, especially applications requiring dedicated environments for testing or development. Furthermore, being part of Linux means it offers similar security and stability as proprietary solutions such as VMware without their increased costs, complexity or vendor lock-in risks.

Creating a virtual machine

Virtual machines (VMs) enable you to run different operating systems on one computer at the same time. Each VM acts like its own computer-in-a-computer with its own network card and disk drive simulated hardware; additionally, each can have its own memory and CPU.

Virtual machines allow you to test software applications or explore security vulnerabilities without placing the physical host operating system at risk. They’re an effective way of becoming acquainted with new operating systems while serving as development environments for software that you hope to deploy in production environments later.

Ubuntu supports several virtualization technologies, including KVM. KVM is a full virtualization solution that utilizes hardware abstractions in the kernel to provide full virtualization functionality, supported by the libvirt front end which offers both GUI and command line access for managing virtual machines using tools such as virt-install, virt-clone, and virt-viewer.

VirtualBox provides an easy way to create virtual machines (VMs). Once installed, VirtualBox features an easy graphical user interface which makes creating and starting up virtual machines effortless. VirtualBox supports Linux, Mac OS and Windows platforms and offers numerous configuration options; once configured you simply click on its green “start VM” button at the center of your screen to begin building or starting one up!

Once your VM boots up, you will be asked for a password. With that password in place, you can login remotely from other machines on your local network or use SSH to connect. However, be mindful that if SSH is used as part of the connection method to access the VM that the host may see your private SSH key which could result in an alert that authenticity of host cannot be verified.

To avoid this issue, you can convert your VM’s default network interface to a bridged network interface by editing the /etc/sol;hosts file using vi and adding an entry with both its IP address and hostname to it.

Once this has been accomplished, you can access your virtual machine (VM) from another computer by entering its IP address into an SSH client and connecting. When connected, basic commands like pinging and ifconfig will let you check whether everything is functioning as expected.
