[Nix-dev] xen nixos guest on a debian host

[Marco Maggesi]

Hello,

I'm trying to use xen on nixos.
I have two problems one for the host, one for the guest:

For the host: I have a 32 bit machine.  When I try to install a nixos
xen host I get the following error during nixos-rebuild

building arch/x86/vdso/vdso32/vdso32.lds

For the guest: When I try to install the nixos xen guest the
nixos-install scripts fails with the message:

error: selector `nixos' matches no derivations

Thanks,
Marco
