Update | Update <code>location</code> path to reflect where your install ISO is located, and the <code>disk</code> path for where VM disk files are intended to be. | ||
The <code>--extra-args "console=ttyS0"</code> option allows a local console to be accessed from the host machine (to allow OS install etc before the VM is on a network), though note that it can't be used with <code>--cdrom</code>, so <code>--location</code> has been used instead. | The <code>--extra-args "console=ttyS0"</code> option allows a local console to be accessed from the host machine (to allow OS install etc before the VM is on a network), though note that it can't be used with <code>--cdrom</code>, so <code>--location</code> has been used instead. Note that where installing Ubuntu guests v22.04 and upwards the kernel and initrd paths on the ISO need to be specified with the ISO location. | ||

You should be presented with the console of the VM as it installs, however if you lose connection etc, connect to the console of the server using <code>virsh console <server-name></code>. Make sure you set a static IP and install SSH during setup (select '''OpenSSH server''' during ''Software selection'' section). Once installation is completed, SSH to the server and setup normal console access (as the instructions in the section below). Its highly recommended that you follow the steps below to ensure that Console access is available via the KVM host if needed. | You should be presented with the console of the VM as it installs, however if you lose connection etc, connect to the console of the server using <code>virsh console <server-name></code>.
