Come across something I've never seen in vSphere 5.0 where powered on guest machines are not able to be vMotioned or Migrated from host1 to any other host within the same Cluster. Though the other hosts 2,3,and 4 can all vMotion to each other. Migration/vMotion fails with the error. Powered off guests however are able to be migrated off to other hosts in the Cluster.
"Failed to start migration pre-copy. Error: The ESX hosts failed to connect over the VMotion network.
vMotion migration [167905794:1447172268721836] failed to create a connection with remote host <10.2.1.64>: The ESX hosts failed to connect over the VMotion network
Migration [167905794:1447172268721836] failed to connect to remote host <10.2.1.64> from host <10.2.10.2>: Network unreachable
The vMotion failed because the destination host did not receive data from the source host on the vMotion network. Please check your vMotion network settings and physical network configuration and ensure they are correct."
Thanks in advance
