Hi Antonie,
Today i and my colleague Abdallah were installed new WANOS_VM_1.8 on the same ESX that holds the old WANOS_VM_1.7(x.x.34.242/23, VLAN34)(out-of-band-mgt port is gig1/0/34), we create new VHD, new VSwitch for the new VM, what happened is that when assign IP (x.x.34.244/23, VLAN34) when VM is up, sudden al the network is hanged and many messages appear on the Cisco_Switch_log which in generaly a MAC flapping between WANOS mgt port with all Cisco Switch Uplinks
interface GigabitEthernet1/0/34
