Performed following steps;


# vi /etc/modprobe.d/xen
adding following line;
options loop max_loop=64


# rmmod -v loop
ERROR: Module loop does not exist in /proc/modules


# modprobe loop
FATAL: Module loop not found.


# grep -i loop /boot/config-`uname -r`
CONFIG_BLK_DEV_LOOP=y
CONFIG_BLK_DEV_CRYPTOLOOP=m
CONFIG_XEN_NETDEV_LOOPBACK=y


loop is not a module.  What can I do?  TIA
