Sekarang saatnya kita merubah default konfigurasi grub agar pada waktu kita reboot, kernel yang dipake adalah kernel xen.
Pastikan untuk mengisi default=0 (penggunaan kernel virtualization) di dalam file grub.conf
# vim /boot/grub/grub.conf

Setelah langkah di atas berhasil saatnya untuk mencoba menginstall OS virtual, di sini kita menggunakan virt-install, biasakan melakukan pengetikan disertai dengan tab, sehingga akan muncul command-command yang lain seperti ketik virt- [klik tab] akan muncul

There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:

2) booting and partitioning software from other OSs
