Hello,

first off all my english is not so well
Many thanks to all of you, bringing me so far on Virtualbox, reading this forum.
Now here come´s the problem:

I have a guest machine running debian lenny and already installed virtualbox with one guest. This one runs fine with NAT.
I have 2 more ip`s configured on the host with eth0:1 and eth0:2. Now i want to install 2 more guests on this machine, one using eht0:1 with a static IP, and the other using eht0:2 with static IP. The host is headless.
How do i configure this with VBoxManage ?
The guests need to talk to each other and have Internet in both ways. (in and out)
If i can configure this guests with eth0:1 and eth0:2 do i need to setup different ports for rdp connections? And where can i change network settings for guests? (root/.virtualbox/...........?)

Thanks

You have to do everything through the VBoxManage interface. Note the IP addresses of the aliased interface and the gateway and DNS server(s) of the Host. Remove those IP addresses from the Host configuration. Install the Guests, set their NIC to bridged and give the VMs the IP address you want them to have. The IP is set inside the VM, not through VB settings.

Hello Sasquatch,

thanks for your quick replay.

How do i set bridged networking? ??
How do i set the ip??

OK now i have it bridgeg with bridgeadapter eth0, setup an IP and the guest says "network unreachable" Thats what the .xml file tells me about the network for the guest. What Information do you need to help me on?

This is all that's needed for the Guest to have Bridged network: And as your XML file has the same, it should have a proper connection to the outside. All the Guest now needs is a valid IP and gateway with DNS and you're good to go.
The Unreachable error means that there is no valid IP address or gateway set.

OK,

this doesn`t work for me.
On the guest :

arp -a ? (192.0.0.0) auf <unvollständig> auf eth0

ifconfig -a give´s me

eth0 Link encap:Ethernet Hardware Adress 08:00.00.00.00 Inet Adress

with an IP

So it should run, but it does not!

Reinstalled the guest no changes.

ping on localhost runs; ping on some domain: unknown host. DNS is in resolv.conf.

ANY Ideas?

Gateway? What does route or route print show?

route

Ziel Router Genmask Flags Metric Ref Use Iface
localnet * 255.255.255.192 U 0 0 0 eth0
default 192.40.112.129 0.0.0.0 UG 0 0 0 eth0

no ideas?

is it a problem to use nat and bridge on one interface (eth0)?

I'm out of ideas. The full command should be like this: To bridge the first NIC to eth0. With that, all VB configuration is done and the rest is up to the Guest OS.

You can have two virtual interfaces, one with Bridged, one with NAT.

It is working!!!!!!!!
The Solution is herehttp://wiki.hetzner.de/index.php/Xen_au ... d_4_IP%27s

Thanks alot.

Now i have to solve the problem, that when i start my vm the following error shows up: It is not because of a missing graphical userinterface (that´s what i found on asking aunt google).

Any Ideas??

You didn't install the xen kernel, did you? VB will not run on that, because Xen itself is a virtualizer.

OK,
do i have to install all this: or which packages?

VBoxHeadless startvm "name" works

aptitude install xen-linux-system-2.6.26-1-xen-686 xen-hypervisor-3.2-1-i386 xen-tools xen-utils-3.2-1 xenstore-utils xen-shell xenwatch

You didn't understand what I just said, you must NOT install those packages, that's the whole point. You linked to a Xen page which has nothing to do with VB and following that howto could very well break VB.

Now, I always assumed you were using a fairly recent version of VB that does NOT need a virtual interface and manual bridges, but which version are you running?
