Prerequisites

This guide assumes you have a basic working environment, run the kvm-ok command to sanity check...

root@kvm-host:# kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used

Install Media

You need to have a local copy of the appropriate ISO. If you have the ISO file already, upload to your KVM server, alternatively download from the site using wget

Create Virtual Machine

Parameter Example Usage
name VM-Name Name of virtual machine (typically this should match the intended hostname of the VM)
description "Test VM to be used for X" Description of virtual machine's purpose etc
os-type Linux OS family, can be Linux, Solaris, Unix or Windows
os-variant ubuntu16.04 Distribution type for the above (run osinfo-query os to view what is available)
ram 2048 vRAM in GB
vcpus 2 vCPUs (cores)
vcpus 2 vCPUs (cores)
disk path /vm-store/images/VM-Name.img,bus=virtio,size=50 Virtual disk path, using virtio bus and with a 50GB disk
graphics none If noneset, VM will be created with a serial display output (as opposed to VNC window)
cdrom /home/user/cdrom.iso Path to installation ISO
network bridge:br0 Network connection details

Create Server (no GUI)

Update paths to reflect where install ISO, and where VM disk files are intended to be

virt-install \
--virt-type=kvm \
--name server-name \
--ram 1024 \
--vcpus=1 \
--os-variant=ubuntu16.04 \
--network=bridge=virbr0,model=virtio \
--graphics none \
--disk path=/mnt/md0/kvm/vm/server-name.img,size=20,bus=virtio \
--extra-args "console=ttyS0" \
--location /mnt/md0/kvm/iso/ubuntu-16.04.3-server-amd64.iso
