You had better starting to read oVirt Administrator Guide at
http://www.ovirt.org/OVirt_Administration_Guide

For you particular questions the answer is almost yes for all and you can
read about them at 6.7.1 8.13 and 8.14
VMware FT (fault tolerance), as you describe in your scenario, is not
available (yet) as far as I know...
