trouble setting up adapters

[richb201]

I am running Vbox on an ubuntu host. The guest is debian. When I start up the Guest, I can see the words "failed to start raised network interfaces". I have two interfaces installed; #1 is NAT called " " #2 is Host Only called "vboxNet0". I am using a wireless since my Dell XPS doesnt have a wired NIC interface. I tried using Bridged network for #1 but got a message "route not found". Can anyone tell me what the issue is? I saw some comments about the automated naming of interfaces, but I don't know how to override that.

When I go to the Host and type ssh bitnami@10.0.2.15 I get "no route to host".
Here is the ifconfig on the host:

Code: Select all

If you have a "NAT" connection, you get by default a 10.0.2.15 IP, which is what you seem to want to connect over. You can't. Not with "NAT".

Please read the following: User Manual, ch. Introduction to networking modes including the Overview table, which shows quickly what kind of connection is required to achieve what you want.

And remember, you can always have more than one network card in your guest to cover multiple scenarios, just like in your case. Try to connect through the HostOnly IP...
