Excellently.  But why believe me?  I’ve just added a node to our cluster and moved a VM throughout the infrastructure in every combination I could think of, from host A to B, from B to A, from A to C, from C to A, from B to C … you get the idea.

While I was going this I was RDP’d into that VM that was being moved using Live Migration.  I ran a continuous ping from that session to the physical default gateway, a Cisco firewall.  This is the result of the ping:

    Packets: Sent = 1174, Received = 1174, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 4ms, Average = 0ms

What was lost?  Zip!  Nada!  How many interruptions did I experience during my RDP session?  Zip!  Nada!

‘Nuff said.
