Now my grub.conf looks like this, default 0 timeout 5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz title Gentoo Xen-2.6.32 root (hd0,0) kernel /boot/xen.gz dom0_mem=4000M module /boot/kernel-2.6.32-xen root=/dev/sdy1 title Gentoo Linux 2.6.32-r7 root (hd0,0) kernel /boot/kernel-2.6.32-gentoo-r7 root=/dev/sdy1 real_root=/dev/sdy1 Gentoo booted fine but i still get the same error whenever i try to create a virtual machine xm create -c /etc/xen/sl4.7-32bits.cfg Using config file "/etc/xen/sl4.7-32bits.cfg".
