+++ This bug was initially created as a clone of Bug #918961 +++
Description of problem:
No size check prior running install (set swap size to > disk size,
should check and stop)
A validation should check if enough space is available and must block the user from continuing if the requested space exceeds the available space.
Also missed "validate the requested sizes page" in rhev-hypervisor6-6.5-20130222.0.auto1707.el6.iso,
so need clone it from upstream bug Component to downstream Component in order to also track it in rhev-h
