In the previous chapters, we explored the creation of KVM guest operating systems on an Ubuntu host using Cockpit and the virt-manager graphical tool. This chapter will focus on creating KVM-based virtual machines using the virt-install and virsh command-line tools. These tools provide all the capabilities of the virt-manager and Cockpit options with the added…

KVM-based virtual machines can easily be configured on Ubuntu using the virt-install command-line tool, the virt-manager GUI tool, or the Virtual Machines module of the Cockpit web console. This chapter will use Cockpit to install an operating system as a KVM guest on an Ubuntu host. The chapter titled Creating Ubuntu 22.04 KVM Virtual Machines…

Earlier versions of Ubuntu provided two virtualization platforms: Kernel-based Virtual Machine (KVM) and Xen. In recent releases, support for Xen has been removed, leaving KVM as the only bundled virtualization option supplied with Ubuntu. In addition to KVM, third-party solutions are available in products such as VMware and Oracle VirtualBox. Since KVM is supplied with…

Virtualization is generically defined as the ability to run multiple operating systems simultaneously on a single computer system. While not necessarily a new concept, Virtualization has come to prominence in recent years because it provides a way to fully utilize the CPU and resource capacity of a server system while providing stability (in that if…

Although Linux has made some inroads into the desktop market, its origins and future are very much server based. It is unsurprising, therefore, that Ubuntu can act as a file server. It is also common for Ubuntu and Windows systems to be used side by side in networked environments. Therefore, it is a common requirement…

Ubuntu provides two mechanisms for sharing files and folders with other systems on a network. One approach is to use technology called Samba. Samba is based on Microsoft Windows Folder Sharing and allows Linux systems to make folders accessible to Windows systems, and also to access Windows based folder shares from Linux. This approach can…

In the previous chapter, we looked at how to display the entire Ubuntu desktop on a remote computer. While this works well if you need to display the entire desktop remotely, it could be considered overkill if you only want to display a single application. Therefore, this chapter will look at displaying individual applications on…

Ubuntu can be configured to provide remote access to the graphical desktop environment over a network or internet connection. Although not enabled by default, it is relatively straightforward to display and access an Ubuntu desktop from a system anywhere else on a network or the internet. This can be achieved regardless of whether that system…

When an Ubuntu system is first installed, it is not configured by default to allow remote command-line access via Secure Shell (SSH) connections. When installed, SSH provides password-protected and encrypted access to the system for the root account and any other users added during the installation phase. This level of security is far from adequate…
