I have two Debian 7 VMs connected to the same virtual wire. When both VM's are running on the same ESXi hosts ping, arp and ssh works. When each VM runs on a different ESXi host in the cluster ping and arp work fine but ssh fails. On the SSH server site I see SYN arriving but the server is failing to reply with SYN ACK.
This is in a nested ESXI 5.5 environment.
vshield manager version 5.5.0.
I'm using vxlan
VMs are debian 7
