# libvirt

## virtio drivers for Windows guests

* https://github.com/virtio-win/virtio-win-pkg-scripts/blob/master/README.md

## Create storage pool

```
# mkdir /var/lib/libvirt/Appliances
# virsh pool-define-as Appliances --type dir --target /var/lib/libvirt/Appliances
# virsh pool-start Appliances

# virsh pool-autostart Appliances
```

Or use GUI...

## Import OVA into libvirt/KVM

```
# virt-v2v \
     -i ova /root/third_party_appliance.ova \ 
     -o libvirt -of qcow2 \
     -os Appliances -n default

```

The options read as:

* `-i ova /root/third_party_appliance.ova` ==  input is an ova file called `/root/third_party_appliance.ova`
* `-o libvirt -of qcow2` == output a libvirt VM in a qcow2 file format
* `-os Appliances` == place the output VM in the Appliances pool
* `-n default` == configure the VM to use the default network
