Install CentOS 8 in Text Mode on a KVM Guest

Install CentOS 8 in Text Mode on a KVM Guest

We have configured a KVM virtualization host in CentOS 8. Now, we are creating a KVM guest and installing CentOS 8 operating system in text mode.

 

Table of Contents:

 

Environment Specification:

We are using a pre-configured KVM virtualization host with following specification.

  • CPU - 3.4 Ghz (2 cores)
  • Memory - 2 GB
  • Storage - 60 GB
  • Operating System - CentOS 8.0
  • Hostname - kvm-virtualization-01.recipes.com
  • IP Address - 192.168.116.206 /24

Install CentOS 8 in Text Mode on a KVM Guest

Create a VM on our KVM Virtualization Host:

To create a CentOS 8 virtual machine, we are required the CentOS 8 ISO file on our KVM virtualization host.

Create a directory to store operating systems’ ISO files.

# mkdir /var/lib/libvirt/iso

Transfer the CentOS 8 ISO file to the KVM virtualization host using WinSCP.

Connect with kvm-virtualization-01.recipes.com using ssh as root user.

# ls /var/lib/libvirt/iso -alh
total 7.0G
drwxr-xr-x.  2 root root   80 Dec 30 14:39 .
drwxr-xr-x. 10 root root  117 Dec 30 14:20 ..
-rw-r--r--.  1 root root 330M Mar  1  2013 CentOS-6.3-x86_64-minimal.iso
-rw-r--r--.  1 root root 6.7G Sep 26 03:36 CentOS-8-x86_64-1905-dvd1.iso

Create a CentOS 8 virtual machine using following command.

# virt-install --name kvm-guest-01 \
> --memory 512 \
> --vcpus 1 \
> --disk size=20 \
> --os-variant rhel8.0 \
> --location /var/lib/libvirt/iso/CentOS-8-x86_64-1905-dvd1.iso \
> --graphics none \
> --extra-args='console=ttyS0'

A virtual machine will be created and the Anaconda installer will be launched automatically.

 

Installing CentOS 8 in Text Mode on a KVM Guest:

After scrolling through a lot of information and messages, the Anaconda installer will take you to the main installation menu.

Starting installer, one moment...
anaconda 29.19.0.40-1.el8 for CentOS Linux 8.0.1905 started.
 * installation log files are stored in /tmp during the installation
 * shell is available on TTY2
 * if the graphical installation interface fails to start, try again with the
   inst.text bootoption to start text installation
 * when reporting a bug add logs from /tmp as separate text/plain attachments
