1. no downtime should happen, as you can upgrade hosts by moving them to 
maintenance, which will live migrate VMs running on them.

2. fedora 18 is EOL, so 'yum update' isn't going to help here.

3. re-install host should refresh vdsm and its dependent packages if the 
repo's configured have newer versions. when the host is in maint, you 
can simply run 'yum update' on the host, then re-activate it (of course 
reboot if kernel got updated, etc.)
