Brand new install, no networking working

Hi.

This is a brand new install: everything new, including Windows7, VirtualBox 4.2.4r81684, and freshly-downloaded Oracle Linux 6.3

Win7 has 4GB memory.

Installed VirtualBox and configured a new OEL machine with 2GB memory, 10GB disk. Configured the CD to boot the guest from the OEL6.3 iso file, and it went through the configuration swimmingly. I chose to install as a Virtualization Host, and all proceeded well, no hiccups at all.

But when I try to do anything network-wise on the guest, it seems I cannot reach the outside world. :oops:

The Win7 system is on a 192.168.0.0/24 network, with IPaddr 192.168.0.16

The Windows host networking shows:
Attached to: NAT
PCnet-FAST III(Am79C973)
Promiscuous Mode: Deny
MAC Address: 080027B77753

On the OEL system:
[root@vm1 ~]# ping 192.168.0.16
connect: Network is unreachable
[root@vm1 ~]# ifconfig
lo (boring stuff)

virbr0 Link encap:Ethernet HWaddr: 52:54:00:a2:9a:49
inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0
UP BROADCAST MULTICAST MTU:1500 Metric: 1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
Collisions:0 txqueuelen:0
RX bytes:0 (0.0b) TX bytes:0 (0.0 b)

/etc/hosts has one 4-bone line and one 6-bone line... all about localhost and localhost.localdomain, et cetera



(I am surprised at the mismatch between MAC Addresses above, but I'm new to VirtualBox; maybe that's normal. I'm also surprised to see no eth0 on the guest, but again, I have nothing against which to compare. BTW: the MAC address for the Win7 system is 00:21:70:xx:xx:xx)

How can I further diagnose this? I've scanned all the sites I could find about this, and read dozens or perhaps hundreds of posts about people with networking problems and how they solved them... but none of them seem to be as fundamental as this; I figure it's me.

Did I miss a step?

From the hosts terminal/command window type VBoxManage showvminfo <VM Name> --details and post here. Replace <VM Name> with the actual name of the VM. Use " " if the name has a space in it.

Note if the host is Windows you need to be in the directory that has VBoxManage.exe for the command to work.

Do you have a router in your LAN?

I am very embarrassed! Somehow, I expected VB to magically reach into the guest and manipulate /etc/sysconfig/network-scripts/ifcfg-eth0 to set it to ONBOOT="yes"

Reality has made a momentary appearance, and I did that myself. Then "service network restart" resolved it!

I can now happily reach out to the net and the world! Woo-hoo! I'm gonna have an orange soda to celebrate.

But wait! What needs to happen to allow the outside world (meaning the intranet outside of the Win7 system) to reach this guest system? As a refresher, Win7 is at IP address 192.168.0.16. Let's say I'm at 192.168.0.18 and I want to ssh into the guest (which all happens to be true!)

How/where do I need to set up such routing? And what else might I need to do (at the Win7 machine and/or at the guest) to make it work? (I have properly configured sshd just right; it's the routing that escapes me.) I may want to access from either Ubuntu or from Win systems, since the guest will eventually be serving web pages.

(If you still need those attributes, say the word and I will oblige.)

So you are using NAT which should have a specific address of 10.0.2.* so there is something wrong. Did you manually set the IP address, and if so you should not.
You did not answer the question of a router. DO you have one?
