the IVS has two Interfaces as a result of the way it is built ; and it is imperative that you leave both of these interfaces in place, otherwise the IVS will not function.
Please try the following :
-import the IVS again from the OVF template ( you can reduce the number of cores and RAM to 1 and 1024 MB , but please leave it otherwise unchanged )
-make sure both the network interfaces are connected to the VLAN that your clients can reach
-start it up - should it hang again at the point where you described, send it a CTRL-ALT-DEL to reboot it gracefully ; the second time it should be able boot fully. ( This happens more often on networks where no DHCP server is present )
-then you can log on to the IVS using root / filewave , and use the imaging-control shell script to configure any networking parameters.
