Hi,
I have a configured cluster with 2 hosts. (ESXi4 and VC 4.0) I installed virtual machines, it's working, and i can ping management network for all host, but when i configure HA, i get the following message: Cannot complete the configuration of the HA agent on the host. See the task details for additional information. Misconfiguration in the host network setup.
Have ideea what is wrong?
Check in the task history to see the reason for the configuration problem.

Be sure that your have shared storage, a pingable default gateway, that your can ping each COS IP, that DNS resolution is working fine, ...
Also you will have (when HA comes up) a warning cause you lack of redoundancy on COS interface.
