Thanks for that, I did that, ran diff on /boot/grub/grub.cfg and found that the following 2 lines were the relevant ones: terminal_input console terminal_output console Knowing that I was able to Google how to do this in Nixos, which is to put the following in /etc/nixos/configuration.nix and run "nixos-rebuild switch". boot.loader.grub.extraConfig = "terminal_input console ; terminal_output console"; > BTW, for kvm you might also want to enable a serial console.

Currently I run my kvm VMs under screen and just use screen -r to get the console. Virsh has some benefits, but so far it hasn't seemed worth the pain. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list luv-main@luv.asn.au https://lists.luv.asn.au/cgi-bin/mailman/listinfo/luv-main
