Virtio[1] is the main platform for IO virtualization in KVM


Example Virtual Machine using virtio:

  • 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


Migrate to virtio[edit]

Replace:

<target dev='hda' bus='ide'/>
<address type='drive' controller='0' bus='0' target='0' unit='1'/>

New options:

<target dev='vda' bus='virtio'/>
