AlmaLinux Versions

Creating a VM

You can create a VirtualBox VM using an AlmaLinux 9 Minimal ISO, which is suitable for most general lab environments and server-based testing.

During creation, you can configure the VM name, OS type, memory, CPU, and disk according to your lab requirements.

For more information, please see Setting Up.

Network Configuration: v8 vs v9

AlmaLinux 8 uses legacy network-scripts, while AlmaLinux 9 uses *NetworkManager- with .nmconnection files. Because of this change, some familiar settings (like BOOTPROTO) no longer exist in EL9 systems.

Configuration File Locations:

Version	Configuration Location
AlmaLinux 8	/etc/sysconfig/network-scripts/ifcfg-*
AlmaLinux 9	/etc/NetworkManager/system-connections/*.nmconnection

Common Setting Differences:

AlmaLinux 8	AlmaLinux 9	Description
BOOTPROTO=dhcp	method=auto	DHCP configuration
BOOTPROTO=none	method=manual	Static IP configuration
IPADDR	address1=	Static IP address
PREFIX	/xx in address	Network prefix
GATEWAY	gateway=	Default gateway
DNS1	dns=	DNS server

Example mapping:

• AlmaLinux 8:

  BOOTPROTO=none
  IPADDR=192.168.1.130
  PREFIX=24
  GATEWAY=192.168.1.1
  DNS1=8.8.8.8

• AlmaLinux 9:

  [ipv4]
  address1=192.168.1.130/24
  gateway=192.168.1.1
  dns=8.8.8.8;
  method=manual

Notes

• BOOTPROTO is deprecated in AlmaLinux 9.
• NetworkManager manages all interfaces by default.
• Static IP configuration uses method=manual.
