Domain Creation

A domain is really the virtual machine. Creating a new domain is just one simple command. virt-install. It takes a lot of parameters though, it is adviseable to read the virt-install manpage.

Creation

Use the following script to create your domains.

createdomain.sh

NAME="stretch-template"
RAM="1024"
LVM_SIZE="4G"
LVM_GROUP="vg2"
GRAPHICS_PROTOCOL="spice" #spice, vnc
OS="debian9"
MEDIA="/mnt/media/debian/stretch/debian-9.1.0-amd64-netinst.iso"

if [ $# -eq 0 ]
then
        echo "${0}: domain-name"
else
        NAME=${1}
fi
LVM_NAME="kvm_${NAME}_vda"

if [ ! -e /dev/${LVM_GROUP}/${LVM_NAME} ]
then

        # create lvm partition
        lvcreate --size ${LVM_SIZE} --name ${LVM_NAME} ${LVM_GROUP}

        # create the virtual machine
        virt-install --name ${NAME} --memory ${RAM} --disk /dev/${LVM_GROUP}/${LVM_NAME},bus=virtio,format=raw --os-variant ${OS} --network bridge=br0,model=virtio --cdrom ${MEDIA} --graphics ${GRAPHICS_PROTOCOL},listen=192.168.1.33,password=${NAME} --noautoconsole --virt-type kvm
else
        echo "${0}: refusing to overwrite existing domain"
fi

Parameters

--name

Give the domain its name. This name is used byt the virsh software as a reference to the domain.

--memory

The amount of memory for the domain. Setting a high value to make the istallation run smoother can be a good idea. It is possible to lower the memory later on.

--disk

The place where the domain has its virtual disk. Here it is an lvm volume using the raw format, but other formats can be used.

--os-variant

Determines the OS running in the domain.

--network

Configure the network interface.

--cdrom

Set the installation media.

--graphics

Configure the guest console.

--noautoconsole

Do not try to connect to the guest console, just start the domain.

--virt-type

Set the hypervisor.
