Check if NTP is correctly configured and the hosts are within a reasonable tolerance of the expected time using "ntpstat -s". The value should ideally be around 200 milliseconds or less.

If that doesn't help, you may need to run "xe pool-sync-database" from the pool master to force all hosts to be synchronized to the master's DB.

The first one still shows up in Xen Center as disconnected. I actually tried a network reset from the console and that seemed to resolve one of my other hosts.

Messages about hosts that can't be contacted sounds like they are having trouble reaching each

other. Does ping between all of the management interfaces seem okay ? Are you doing bonds 

on the management interfaces ? If so you might want to back off to just a single management 

interface across your pool if their is issues between your bonding and your switches.
