[Nix-dev] GRUB install error during 'nixos-install'

[Mait]

Hi, all nix-dev.

I've tried to install nixos to kvm virtual machine. But GRUB install 
failed at last stage of 'nixos-install'.

I've found some related link from google but didn't help. 
https://lists.gnu.org/archive/html/help-grub/2012-04/msg00075.html

Host OS is Ubuntu 13.10. This is output from nixos-install and vm's 
disk, partition info.
