{"name":"xen","summary":"Type-1 hypervisor intended for embedded and hyperscale use cases","description":"The Xen Project Hypervisor is a virtualisation technology defined as a *type-1\nhypervisor*, which allows multiple virtual machines, known as domains, to run\nconcurrently with the host on the physical machine. On a typical *type-2\nhypervisor*, the virtual machines run as applications on top of the\nhost. NixOS runs as the privileged **Domain 0**, and can paravirtualise or fully\nvirtualise **Unprivileged Domains**.\n\nUse with the `qemu_xen` package.\n\nIncludes:\n* `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.\n* `xen-4.22.0`: The Xen Project's multiboot binary, available on the `boot` output of this package.\n* `seabios`: Support for the SeaBIOS boot firmware on HVM domains.\n* `ovmf`: Support for the OVMF UEFI boot firmware on HVM domains.\n* `ipxe`: Support for the iPXE boot firmware on HVM domains.","homepage_url":"https://xenproject.org/","license":"CC-BY-4.0","attribute_paths":["xen"],"releases":[{"version":"4.22.0","last_updated":"2026-10-06T17:11:02Z","platforms":[{"arch":"x86-64","os":"Linux","system":"x86_64-linux","attribute_path":"xen","commit_hash":"e2ccecbf30866802b1db536246e0939eccbd7bfb","date":"2026-10-06T17:11:02Z","outputs":[{"name":"out","path":"/nix/store/hnvys8sm9qfxka50wrrdm9nis62kiryi-xen-4.22.0","default":true},{"name":"man","path":"/nix/store/3kaik0a350i17qr53zzfxq9y6vrdd0jx-xen-4.22.0-man","default":true},{"name":"boot","path":"/nix/store/af81p0p9qv65r83957wksy4l380zmlhn-xen-4.22.0-boot"},{"name":"dev","path":"/nix/store/zif17yvjas3cda8f7sya8sciwx3pwz4y-xen-4.22.0-dev"},{"name":"doc","path":"/nix/store/39hrjskwmzpx1zv34wlw2vd420f5hk1z-xen-4.22.0-doc"},{"name":"ocaml","path":"/nix/store/swabhvgnsqcbk2nbb2zswlca203c27rb-xen-4.22.0-ocaml"}],"broken":false,"insecure":false}],"platforms_summary":"Linux","outputs_summary":"man
