I recently added a new host to me ESXi 5.0 cluster and i am receiving the following 'info' messages within vcentre:
Alarm 'Network connectivity lost': an SNMP trap for entity mvm01 was sent
This error has been pretty steady since the host has been up and added to the cluster.
I am unable to find any network issue's and responses to and from the host look good with no latency.
Don't know if this is any help after so long; I found this post while investigating a similar problem, which I've now managed to resolve.
The critical status alert for "Network Connectivity Lost" appears to be configured to repeat forever by default. To change it:
Hope this helps.

Since this is the ESXi 5 forum these links will not be applicable. It is very nice to try to be helpful, but it is also good to do some verifying that the information seems to be relevant.
I have seen similar errors when DNS is not functioning properly and that it is configured properly both on the ESX hosts and the vCenter server (I usually go as far as adding the enteries into the HOSTS file on the vCenter server).
I would verify name pings to-and-from on the hosts as well as the vCenter server. This type of problem in particular may cause bigger issues as well.
