Getting following error when migrating vms from one host to another on ESXi 5.5

When I migrate a powerd off vm all goes just fine but when I try to migrate a powered on vm, it goes to 14% and then after a few minutes, I get this error: A general system error occured. The vmotion migration failed beacuse the ESX host were not able to connect over the vmotion network. Check the vmotion network settings and physical network configuration..

Migrating a powered off VM does not require the hosts to communicate; the VM just gets unregistered on the first host and registered on the new host.

You need to configure vmkernel adapters on each host and enable vMotion on the vmkernel port.

I enabled vmotion on the iscsi vswitch which we usually do...

Is it enabled on the vmkernel port on each host?

Go to Home->Inventory->Hosts and Clusters.  Click on a host.  Click on the Configuration tab.  Select "networking."  Find the virtual switch that has your VMkernel port.  Click "Manage Virtual Adapters".  Select each VMkernel port (usually named vmk0, vmk1, etc.) and see which one has vMotion: Enabled.

Verify that each host's vMotion-enabled port is in the same subnet.  (Make sure to check both the IP address and the subnet mask.)

If they're all configured correctly, then you likely have a problem on your network.

Is it ok to have the vmotion on a vswitch which is the fibre for the iscsi?
Right now we have it on the iscsi vswitch but that goes to an old san which will be going away so I could put it on the vswitch vmkernal port for the fiber iscsi if that is ok?

Typically, it's best to keep iSCSI traffic segregated, but you can probably get away with it.

have you tried to use vmkping to see if both host are able to reach each other on their vmkernak adapters?
