Please confirm if I am right : 

#!/bin/sh 

cat << EOF 
menuentry "Xen 3.5 / Ubuntu, 2.6.31.6-xen1" { 
    insmod ext2 

    set root=(hd0,1) 
    multiboot /boot/xen-3.5.gz <- This is the Xen VMM proper ???
    module /boot/vmlinuz-2.6.31.6-xen1 dummy=dummy dom0_mem=1024M root=/dev/sda1 ro <- This is linux kernel with pvops right ???

    module /boot/initrd.img-2.6.31.6-xen1 
} 

EOF
so in my case , I have compiled Linux kernel containing pvops ; Now , I also need Xen VMM ?? right ??

Please confirm

Thank you very very much,

You need to build the hypervisor as well. Look at:
