[Openstack] [Cinder][VMWare]Not able see attached volume without instance reboot.

I am using the Debian VMDK image for testing Cinder with VMware vCenter
It seems by default the above debian vmdk image not configured to load
"acpiphp" kernel module at boot time.
Here is /etc/module file after instance launch
# cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.
# dmesg |grep acpiphp:
Because of this I am not able see attached volume in instance. After
attaching volume I did the below steps manually and still it requires VM
reboot to see attached volume.
# modprobe -v acpiphp
root at debian:~# dmesg |grep acpiphp:
[ 2614.352369] acpiphp: ACPI Hot Plug PCI Controller Driver version: 0.5
[ 2614.352765] acpiphp: Slot  registered
[ 2614.352873] acpiphp: Slot  registered
# echo “acpiphp” >> /etc/modules
My question is:
Is there any tool in Linux to edit the above VMDK and add acpiphp to load
at boot time?
what are other kernel module required to hotplug volume to running instance?
Thanks & Regards
