Some additional info: I tried the host machine reboot after installing a
qcow2 format ubuntu image as VM. And it works fine i.e. after power-cycling
the host node, the VM is able to boot again. I suspect either there is bug
with Grizzly release in handling certain type of ISO files or the ISO needs
to be built keeping certain things in mind. FYI, the ISO image that I am
using is an in-house custom built image which we have been using
successfully across multiple platforms as well as on Openstack Essex
release.
