48 +# Converting OVA images for use with libvirt

50 +OVA images can be [imported](https://www.redhat.com/en/blog/importing-vms-kvm-virt-v2v) into libvirt using the `virt-v2v` utility (from the `libguestfs-tools` Ubuntu package).
51 +
52 +They can be imported directly using the `libvirt` output method, but I prefer only generating the necessary files, using the `local` output method. This way, I can easily adjust the VM settings before importing them into libvirt.
53 +
54 +```bash
55 +virt-v2v -i ova /path/to/source.ova -o local -of qcow2 -os /path/to/destination/dir

57 +
58 +This will create an XML file with the VM configuration and a QCOW2 file for each disk in `/path/to/destination/dir`. The XML file can be adjusted and then imported using `virsh define`.
