Example Virtual Machine using virtio[edit]

virt-install --autostart --check all=on --name YOUR_VM_MACHINE --memory VM_MEMORY --vcpus VM_CPUs --os-variant ubuntu18.04 --cdrom VM_INSTALLATION_MEDIA --disk /path/libvirt/VM_STORAGE_POOL_NAME/YOUR_VM_MACHINE.qcow2 --noautoconsole --wait TIME_TO_WAIT --network type=direct,source=eno111,source_mode=bridge,model=virtio

virt-install 
 --autostart
 --check all=on
 --name YOUR_VM_MACHINE
 --memory VM_MEMORY
 --vcpus VM_CPUs
 --os-type linux
 --os-variant ubuntu20.04
 --graphics none
 --wait TIME_TO_WAIT
 --network type=direct,source=eno111,source_mode=bridge,model=virtio
 --disk /path/libvirt/VM_STORAGE_POOL_NAME/YOUR_VM_MACHINE.qcow2
 --cdrom PATH_TO_INSTALLATION_MEDIA

Example:

virt-install 
 --autostart
 --check all=on
 --name YOUR_VM_MACHINE
 --memory 8192
 --vcpus VM_2
 --os-type linux
 --os-variant ubuntu20.04
 --disk /srv/libvirt/YOUR_VM_MACHINE.qcow2,size=25
 --graphics none
 --network type=direct,source=eno111,source_mode=bridge,model=virtio

Other options:

--qemu-commandline

Using kickstart file:

--extra-args "ks=file:/ks.cfg console=ttyS0"
