Troubleshoot performance and isolate bottlenecks in Linux – Virtual Machines [1]

Troubleshoot performance and isolate bottlenecks in Linux. Performance issues occur in different operating systems or applications, and every issue requires a unique approach to troubleshoot
Each of these areas generates different symptoms (sometimes simultaneously) and requires a different diagnosis and solution.. There are instances where performance problems could be caused by a misconfiguration of the application/setup
This situation leads to more requests flowing back to the origin server, instead of being served by cache.. Another example would be when the redo log of a MySQL/MariaDB is located on the operating system (OS) disk or on a disk that is not up to the database requirements

Overview of virtual machines in Azure – Azure Virtual Machines [2]

Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets. Azure virtual machines are one of several types of on-demand, scalable computing resources that Azure offers
This article gives you information about what you should consider before you create a virtual machine, how you create it, and how you manage it.. An Azure virtual machine gives you the flexibility of virtualization without having to buy and maintain the physical hardware that runs it
– Development and test – Azure virtual machines offer a quick and easy way to create a computer with specific configurations required to code and test an application.. – Applications in the cloud – Because demand for your application can fluctuate, it might make economic sense to run it on a virtual machine in Azure

Common Hyper-V Problems and How to Fix Them [3]

Hyper-V has come a long way since its humble beginnings nearly a decade ago. Although Hyper-V has been improved in almost every way imaginable since its debut in Windows Server 2008, there are some common Hyper-V related issues that continue to affect virtualization administrators
As someone who has written multiple books about Hyper-V, I receive a lot of emails from readers, asking about various Hyper-V issues. One of the questions I am asked most frequently is why virtual machines run so slowly.
In other words, the host server has limited hardware resources available, and those resources must be shared among the virtual machines and by the hypervisor itself. Any time inadequate hardware resources are available, performance can suffer

Virtualization [4]

In computing, virtualization or virtualisation (sometimes abbreviated v12n, a numeronym) is the act of creating a virtual (rather than actual) version of something at the same abstraction level, including virtual computer hardware platforms, storage devices, and computer network resources.. Virtualization began in the 1960s, as a method of logically dividing the system resources provided by mainframe computers between different applications
Since then, the meaning of the term has broadened.[1]. Hardware virtualization or platform virtualization refers to the creation of a virtual machine that acts like a real computer with an operating system
For example, a computer that is running Arch Linux may host a virtual machine that looks like a computer with the Microsoft Windows operating system; Windows-based software can be run on the virtual machine.[2][3]. In hardware virtualization, the host machine is the machine that is used by the virtualization and the guest machine is the virtual machine

Chapter 1. First Steps [5]

Oracle VM VirtualBox is a cross-platform virtualization application. What does that mean? For one thing, it installs on your existing Intel or AMD-based computers, whether they are running Windows, macOS, Linux, or Oracle Solaris operating systems (OSes)
As an example, you can run Windows and Linux on your Mac, run Windows Server on your Linux server, run Linux on your Windows PC, and so on, all alongside your existing applications. You can install and run as many virtual machines as you like
Oracle VM VirtualBox is deceptively simple yet also very powerful. It can run everywhere from small embedded systems or desktop class machines all the way up to datacenter deployments and even Cloud environments.

Citrix Hypervisor 8.2 [6]

Use the following configuration limits as a guideline when selecting and configuring your virtual and physical environment for Citrix Hypervisor. The following tested and recommended configuration limits are fully supported for Citrix Hypervisor.
More information about supported hardware can be found on the Hardware Compatibility List. Consult your hardware manufacturers’ documented limits to ensure that you do not exceed the supported configuration limits for your environment.
Consult your guest OS documentation to ensure that you do not exceed the supported limits.. The maximum amount of physical memory addressable by your operating system varies

5 Benefits of Virtualization [7]

Virtualization is the foundation of cloud computing—what are some of the key benefits it can bring to your organization?. Many IT organizations deploy servers that are only running at a fraction of their capacity, often because they are dedicating their physical server to a specific application
In efforts to drive higher capacity utilization and reduce costs, virtualization was created. This article will provide an overview of virtualization and its key components and explain five of the (many) benefits your organization could enjoy through virtualization:
Move to be more green-friendly (organizational and environmental). Virtualization uses software to create an abstraction layer over the physical hardware

4.10. Memory Overcommitment [8]

In server environments with many VMs, the Guest Additions can be used to share physical host memory between several VMs. This reduces the total amount of memory in use by the VMs
The Guest Additions can change the amount of host memory that a VM uses, while the machine is running. Because of how this is implemented, this feature is called memory ballooning.
Memory ballooning does not work with large pages enabled. To turn off large pages support for a VM, run VBoxManage modifyvm

Characteristics of Virtualization [9]

Prerequisite – Virtualization In Cloud Computing and Types. The ability to control the execution of a guest program in a completely transparent manner opens new possibilities for delivering a secure, controlled execution environment
A virtual machine manager can control and filter the activity of the guest programs, thus preventing some harmful operations from being performed. Resources exposed by the host can then be hidden or simply protected from the guest
Example-1: Untrusted code can be analyzed in Cuckoo sandboxes environment.. The term sandbox identifies an isolated execution environment where instructions can be filtered and blocked before being translated and executed in the real execution environment.

Key metrics for monitoring VMware vSphere [10]

VMware’s vSphere is a virtualization platform that allows users to provision and manage one or more virtual machines (VMs) on individual physical servers using the underlying resources. With vSphere, organizations can optimize costs, centrally manage their infrastructure, and set up fault-tolerant virtual environments
VMware also provides VM cluster management tools like the Distributed Resource Scheduler (DRS), which uses vMotion to automatically distribute shared physical resources to VMs based on their needs. In cases where downtime is expected for a particular server (e.g., for maintenance) or a server is overburdened, vMotion can also be used to migrate a VM to another server with zero downtime
If your organization is using vSphere to run applications, it’s vital that you pay close attention to your environment’s overall performance and capacity at different layers, including the VMs running workloads and the underlying hosts. This helps ensure that available resources meet the demands of the applications and services running on your vSphere infrastructure.

Physical Servers vs. Virtual Servers: Which Works Best for Your Business? [11]

Virtual Servers: Which Works Best for Your Business?. Given today’s fast-paced, technology-driven environment, most IT decision-makers and business owners would agree that a server is the heart of their business
It is an essential element of an organization’s IT infrastructure. Installing a server is a no-brainer for businesses to stay competitive
As an IT pro, you must help make the decision-making process simple and easy for your organization. It is important that you understand your business’s unique goals and priorities in order to choose the right server configuration that will meet both current and future needs.

What Is a Virtual Machine? [12]

When most people think of virtual machines, they tend to think of those once-futuristic virtual reality sets or a way to play old video games on your modern computer. But those aren’t the virtual machines we’re talking about here
Whether you use macOS, Windows, Linux, iOS, or Android, you probably have a list of reasons why your operating system is superior. But, if you’re going to make it as a developer, you’ll have to explore other operating systems if you want your applications and web pages to work everywhere
And, after reading this article, you will too once you understand what they are, how they work, and why people use them.. Before we get into the details of virtual machines, it’s important first to understand what an operating system is and how it works.
