Change:
migrated from python branch issue tracker
I have tested = true; and that works for me. virt-manager could use some improvements regarding permissions though. I'm thinking about letting users in group "libvirtd" get access to the libvirtd daemon socket, instead of having it only available to root. This is what Ubuntu does.
I'm closing this as virt-manager seems to work just fine. (And users in the "libvirtd" group now have access.)

<ins> ** Status The code in master as of June 2015 should be able to prepare a bootable NixOS for Raspberry PI 2. There are still some drawbacks: NixOS does not provide a /boot/config.txt (the FAT32 partition). Making NixOS work in the Raspberry PI 2 is mainly the result of the recent work of ambro718, Dezgeg and viric (#nixos@irc.freenode.net). ** Download If you want to test, you can flash this 4GB SD image (DOS partition table + fat32 + ext4 rootfs): magnet:?xt=urn:btih:0def3f6acb3bceddb22cb24098f58e40e2853ec2&dn=rpi2-nixos-4b09501f2-img.xz&tr=udp%3A%2F%2Fopen.demonii.com%3A1337&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80 Then you should be able to nixos-rebuild any configuration.nix changes. The image is the result of a "nixos-install" alone. No root password has been set, and it does not include a nixpkgs checkout or channel. In fact I (viric) created the FS into a NBD, not a real SD, to create this image. </ins>
