How to Configure a Virtual Machine Host

Virtual machines offer an ideal way to explore different operating systems and run production applications.

Install virt-manager and bridge-utils on your Ubuntu host computer, then add users to the libvirt group so they can create and start virtual machines (VMs).

Next, choose a disk location for the virtual machine (VM). This space will be allocated specifically to this VM on your host computer and should be visible.

What is virtualization?

Virtualization is the practice of creating an abstract layer over physical hardware to allow multiple operating systems and applications to run simultaneously on it, increasing efficiency while decreasing costs and improving reliability.

To achieve this, virtual machines (VMs) are granted access to all of the same physical system resources as their host machine, but interact with these resources through software emulation rather than physical access. This ensures that VM operations do not get disrupted by processes running on either of them simultaneously, nor other VMs on that same system.

Virtual machines (VMs) act like completely separate computers, enabling desktop users to run applications intended for different operating systems without switching computers or rebooting. For servers, virtualization enables multiple application programs to be stacked onto one physical server as virtual servers – reducing server needs while optimizing resource utilization – while IT administrators can quickly clone or backup entire servers to quickly recover from catastrophic failures or test changes on production systems.

Installing Ubuntu on VMware

Ubuntu can be installed as a virtual guest operating system on VMware by selecting File > New Virtual Machine and choosing Custom (advanced). Next, in the next window select Ubuntu ISO image then Click Browse button.

As soon as Ubuntu boots, it will take you through a series of relatively quick setup screens. It will ask what kind of keyboard you are using and whether or not to download updates during installation, among other questions.

At the conclusion of this process, your Ubuntu VM should automatically boot and log you into its GUI. If you want to enhance its performance further, VMware Tools are available that can enhance video resolution and mouse movement – but they may also consume resources. Therefore, for optimal results it’s best to install them once your configuration of your VM has been finalised and remove them later as desired; they can always be reinstalled later if required.

Configuring a virtual network interface

After installing Ubuntu, a virtual machine host can accept network traffic. To do this, configure the virtual network interface of your VM in much the same manner as configuring physical network connections.

First, log into the VM and open a terminal window. Type “pwd” to determine your path; then “ifconfig” and receive a list of network configuration settings such as its MAC address and IP address.

The default VM network setup permits communication between virtual machines (VMs) and locations outside their host, increasing security but also creating problems on other hosts. To reduce this risk, a VLAN can help by adding tags to network packets so as to group hosts together – perfect when controlling access to resources available within VMs.

Configuring a serial port

Many operating systems provide serial console login, allowing users to gain access to virtual machines (VMs) without the need for SSH connectivity. It is important to keep in mind that this connection could be cut by anyone with physical access to the device and therefore it is vital that a strong password-based authentication scheme be put into place for added protection.

To configure a serial console on a VMware virtual machine, start by configuring an application on the host system to send its output through a named pipe. A program such as HyperTerminal, Putty or TeraTerm which runs across platforms and emulates VT102 is ideal. Next, test out login programs on both sides; in Ubuntu this could include screen or byobu; as long as booting with on-dtr-low enabled (this disables a script which would otherwise disconnect users), rebooting will not result in them automatically logging out automatically logging out automatically!
