xen

The Xen Project Hypervisor is a virtualisation technology defined as a *type-1 hypervisor*, which allows multiple virtual machines, known as domains, to run concurrently with the host on the physical machine. On a typical *type-2 hypervisor*, the virtual machines run as applications on top of the host. NixOS runs as the privileged **Domain 0**, and can paravirtualise or fully virtualise **Unprivileged Domains**. Use with the `qemu_xen` package. Includes: * `xen-4.22.0.efi`: The Xen Project's [EFI binary](https://xenbits.xenproject.org/docs/4.22-testing/misc/efi.html), available on the `boot` output of this package. * `xen-4.22.0`: The Xen Project's multiboot binary, available on the `boot` output of this package. * `seabios`: Support for the SeaBIOS boot firmware on HVM domains. * `ovmf`: Support for the OVMF UEFI boot firmware on HVM domains. * `ipxe`: Support for the iPXE boot firmware on HVM domains.
