# Internal drivers

- Hypervisor drivers
- Storage drivers
- Node device driver
- Secret driver

The libvirt public API delegates its implementation to one or more internal drivers, depending on the connection URI passed when initializing the library. There is always a hypervisor driver active, and if the libvirt daemon is available there will usually be a network and storage driver active.

## Hypervisor drivers

The hypervisor drivers currently supported by libvirt are:

- LXC - Linux Containers
- OpenVZ
- QEMU
- Test - Used for testing
- VirtualBox
- VMware ESX
- VMware Workstation/Player
- Xen
- Microsoft Hyper-V
- Virtuozzo
