No, I am using 64-bit vm (qemu-kvm) on 64 bit kernel (Ubuntu 8.04 LTS)
And as I am using kvm, it directly expose hardware to guest, without
I have built 64 bit LFS (v 6.3) on 64 bit host, with multilib.

I know this should go in another discussion but I think It's worth noting
My grub is also not working properly. If I press any key other than enter,
grub freezes, and have to restart kvm. However If I press enter than
kernel boots normally.
