hi
do you know how to do this !??
From a previous post:
Find the VBox Host Only Adapter that your IOU VM is using:

Open a command prompt, type ipconfig and find the corresponding VBox Host Only Adapter. This is what it looks like on my PC:
Ethernet adapter VB HOA #2 IOU:
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::39b0:b4e3:a49d:5022%44
IPv4 Address. . . . . . . . . . . : 192.168.133.2
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . :
Then change the IP address in the Host Binding field of "Local server" (Edit -> preferences -> GNS3 Server) to match the IP address of the VB HOA (it should be listed in the drop down menu of the text field).

If the IP address that your IOU VM is using isn't in the same subnet, change it. Just to be clear, don't assign 192.168.133.2 to your IOU VM's nic though.

I set a VB HOA aside for the IOU and configured it to provide DHCP that only gives out one IP Address.

Don't forget to change the Remote Server address in GNS3's preferences to reflect any change in the IOU VM's IP address:

This works for me after quite a bit of research on why my VBox VM's IOU devices weren't pingable but a VMWare test VM had no problems one configured. I hope this will help someone.
