Posted: 2024-01-06 In the previous chapters, we explored the creation of KVM guest operating systems on an AlmaLinux 9 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…

Posted: 2024-04-22 The previous chapter explored how to create KVM virtual machines on AlmaLinux 9 using the Cockpit web tool. With the caveat that virt-manager may one day be discontinued once the Virtual Machines Cockpit extension is fully implemented, this chapter will cover using this tool to create new virtual machines. Starting the Virtual Machine…

Posted: 2024-04-08 KVM-based virtual machines can easily be configured on AlmaLinux 9 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 AlmaLinux 9 host. The chapter titled “Creating KVM…

Posted: 2024-03-18 Earlier versions of Red Hat Enterprise Linux (on which AlmaLinux is based) 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 AlmaLinux 9. In addition to KVM, third-party solutions are available in products…

Posted: 2024-02-26 Although Linux has made some inroads into the desktop market, its origins and future are very much server-based. It is unsurprising, therefore, that AlmaLinux 9 can act as a file server. It is also common for AlmaLinux and Windows systems to be used side by side in networked environments. Therefore, it is a…

Posted: 2024-02-14 AlmaLinux 9 provides two mechanisms for sharing files and folders with other systems on a network. One approach is to use a technology called Samba. Samba is based on Microsoft Windows Folder Sharing and allows Linux systems to make folders accessible to Windows systems and access Windows-based folder shares from Linux. This approach…

Posted: 2024-02-28 In the previous chapter, we looked at how to display the entire AlmaLinux 9 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…

Posted: 2024-02-25 AlmaLinux 9 can be configured to provide remote access to the graphical desktop environment over a network or internet connection. Although not enabled by default, displaying and accessing an AlmaLinux 9 desktop from a system anywhere else on a network or the internet is relatively straightforward. This can be achieved regardless of whether…

Posted: 2024-02-22 When an AlmaLinux 9 system is first installed, it is configured by default to allow remote command-line access via Secure Shell (SSH) connections. SSH provides password-protected and encrypted access to the system for the root account and any other users added during the installation phase. However, this level of security is inadequate and…

Posted: 2024-02-14 A firewall is vital in protecting a computer system or network of computers from external attacks (typically from an external source via an internet connection). For example, any computer connected directly to an internet connection must run a firewall to protect against malicious activity. Similarly, any internal network must have some form of…
