In this blog post, we’ll guide you through step-by-step instructions on creating a virtual machine in VMware vSphere Client – let’s get started!

How to Create a Virtual Machine in VMware Vsphere Client

Overview of Virtualization and VMware vSphere

Virtualization is creating a virtual version of something, such as an operating system, a server, or a storage device. VMware vSphere is a powerful server virtualization platform that consolidates your physical servers into fewer machines and improves your data center efficiency. This article will show you how to create a virtual machine in VMware vSphere Client.

What is a Virtual Machine?

A virtual machine is a software computer that, like a physical computer, runs an operating system and applications. The major difference between a physical computer and a virtual machine is that the virtual machine exists within a layer of abstraction on top of the physical hardware.

This layer is known as the hypervisor. On top of the hypervisor, multiple virtual machines can be created, each running its own operating system and applications.

The benefits of using virtual machines include improved utilization of hardware resources and flexibility regarding hardware configuration, scalability, portability, and safety.

Regarding resource utilization, because multiple virtual machines can share physical hardware resources, they can be used more effectively than if they were dedicated to a single physical machine.

For example, suppose two virtual machines are each configured to use one processor core, but both are idle most of the time. In that case, the processor cores can be employed by other virtual machines with a greater need for processing power.

In addition, virtual machine technology makes it possible to change the configuration of hardware resources assigned to a particular virtual machine without powering down or rebooting it.

For example, if a virtual machine requires more memory than was originally allocated, that memory can be added dynamically while the virtual machine is still running. This increased flexibility can result in greater efficiency in utilizing hardware resources.

Step-by-Step Guide to Creating a Virtual Machine in VMware Vsphere Client

This section will describe, step-by-step, how to create a virtual machine in VMware vsphere Client.

1) Log into the VMware vSphere Client.

2) In the left-hand pane, select the host to create the virtual machine.

3) Right-click on the host and select “New Virtual Machine…” from the context menu.

4) The “Create New Virtual Machine” wizard will appear. On the first screen, give the VM a name and select where it will be stored. Then click “Next.”

5) Select the datastore where you want to store the VM files. Click “Next.”

6) Select the OS Type and Version for your VM. Click “Next.”

7) Specify how much memory you want to allocate to the VM. Click “Next”.

8) Select whether you want to create a new or use an existing disk. If creating a new disk, select its size. Then click “Next.”

9) Review your settings and click “Finish” to create the virtual machine.

Choosing the Right System Resources for Your VM

When creating a virtual machine, you must specify the number of system resources the VM can use. These resource allocations are made when you create the VM, and they cannot be changed without deleting and recreating the VM.

There are four types of system resources that you can allocate to a VM: CPU, memory, storage, and networking.

CPU: The CPU allocation specifies the number of virtual CPUs (vCPUs) that the VM can use. A vCPU is a synthetic CPU the VM uses, not a physical CPU core from the host server.

The number of vCPUs you can allocate to a VM depends on the type of processor in the host server and the version of VMware vSphere you are using.

Memory: The memory allocation specifies the amount of physical RAM (in GB) the VM can use. Memory allocations for VMs must be made in increments of 256 MB.

The maximum amount of memory you can allocate to a VM depends on the type of processor in the host server and the version of VMware vSphere you are using.

Storage: The storage allocation specifies the maximum amount of disk space (in GB) that the VM can use. Storage allocations for VMs must be made in increments of 1 GB. There is no limit to the amount of storage you can allocate to a VM.

However, keep in mind that each additional GB of storage allocated to a VM will increase the amount of disk I/O that the host server must perform.

Networking: The networking allocation specifies the maximum network bandwidth (in Mbps) the VM can use. Networking allocations for VMs must be made in increments of 1 Mbps.

No limit exists to how much network bandwidth you can allocate to a VM. However, be aware that any excess network traffic generated by the VM may impact other VMs running on the same host server.

Advanced Configuration Options for Your VM

Several advanced configuration options can be applied to your VM in VMware vSphere Client.

These options can be found in your VM’s “Advanced Settings” dialog, accessible from the “Edit Settings” dialog. Some of the most commonly-used advanced settings are:

  • Memory reservation: This setting lets you specify how much memory should be reserved for your VM. Setting a higher memory reservation is recommended if you run memory-intensive applications on your VM.
  • CPU cores per socket: Each virtual CPU is treated as a separate core by default. However, you can change this setting to allow multiple virtual CPUs to be grouped together into a single socket. This can improve performance for specific workloads.
  • Enable nested virtualization: Nested virtualization allows you to run a hypervisor within your VM. This can be useful for testing and development purposes. However, it comes with some performance penalties and should only be enabled if absolutely necessary.

These are just a few advanced configuration options available in VMware vSphere Client. Experiment with different settings to see what works best for your particular workloads and use cases.

Tips for Creating Multiple VMs

If you need to create multiple virtual machines (VMs) in VMware vSphere, there are a few things to remember to make the process as efficient as possible.

  1. When creating multiple VMs, it’s best to use templates. This will allow you to quickly provision new VMs without going through the entire creation process each time.
  2. If you’re creating VMs with similar specifications, consider using clones. Clones can be created from existing VMs, saving you time by pre-populating many settings.
  3. Make sure to size your VM disk images properly. If you plan on storing a lot of data on the VM, allocate enough disk space accordingly. Otherwise, you may run into performance issues down the road.
  4. Lastly, don’t forget to apply any necessary updates and patches to your templates and VMs before rolling them out into production. This will help ensure your systems are up-to-date and secure from potential threats.

Troubleshooting Virtual Machine Creation Issues

A few potential issues can arise when creating a virtual machine in VMware vSphere Client. Fortunately, there are also a few simple troubleshooting steps that can be taken to address these issues.

One common issue is that the VM may fail to power on after creation. This can be due to several factors, such as incorrect settings or insufficient resources.

Another potential issue is that the VM may be unable to connect to the network. This can again be due to incorrect settings or insufficient resources.

Fortunately, these issues can be addressed by simply checking the VM settings and ensuring all necessary resources are available. If the problem persists, it may be necessary to contact VMware support for assistance.


Creating a virtual machine in VMware vSphere Client is easy and straightforward. With the Cloud Management Suite, you can quickly set up and manage your cloud infrastructure to give your users the best performance and reliability.

This powerful feature will help you save time and money while offering a secure environment for your virtual machines.

We hope our guide has given you some insight into creating a virtual machine in VMware vSphere Client – now it’s time to get started!
