Hello, it is the first time I use VB. I installed VB on my headless Debian Lenny:
VBoxManage createvm -name "server2" -register
VBoxManage modifyvm "server2" -memory "256MB" -acpi on -boot1 dvd -nic1 nat
VBoxManage createvdi -filename "server2.vdi" -size 20000 -register
VBoxManage modifyvm "server2" -hda "server2.vdi"
VBoxManage registerimage dvd /root/debian-501-i386-netinst.iso
VBoxManage modifyvm "server2" -dvd /root/debian-501-i386-netinst.iso

Ihave 2 networking problems:

My guest server is in a different subnet then my host server. why? do I have to change nat to bridge?

I have 2 FE interfaces on my server: host server has eth0, can I make the guest server using eth1 instead of eth0? .. then is it possible do give guest server 2 interfaces?

thanks

The subnet is due to the NAT setting.

You can use two NICs in a VM. For your bridged question, is eth1 active and connected? If it doesn't have a cable attached to it, you can just as well set the VM to use a Not Attached NIC, as it won't work. No cable = no connection.

first thanks for your answer. the first problem now is: host has eth0, guest uses the same interface. how can i make it using bridged instead of nat? I tried
VBoxManage modifyvm "server2" -memory "256MB" -acpi on -boot1 dvd -nic1 bridged
bt it says error: Invalid type 'bridged' specfied for NIC 1. So I tried hostif but when I start VM I get
Error: failed to start machine. Error message: Failed to initialize Host Interface Networking.

no tutorial nowhere to setup networking for host and guest server in bridge mode

There is help output if you read the Manual, or just run VBoxManage without arguments. You need to provide a name for the interface along with the attached method. Would become:

VBoxManage modifyvm "server2" -nic1 hostif -hostifdev eth0
VirtualBox Command Line Management Interface Version 2.0.8

error: Invalid NIC number ''

Hmm, since you use 2.0.8, and I use 2.2.4, there are differences in the command. As I said, check it all by running VBoxManage without arguments. You can get a little more specific help if you enter only one argument, like VBoxManage modifyvm.
And one other thing: Direct NIC access is available since 2.1.0, so your version still requires a virtual NIC to be created and bridged to your physical NIC with bridge-utils. It's best to upgrade to 2.1.4 or 2.2.4 for the new feature if you don't want or know how to create a bridge.

I reinstalled VB 2.2.4 and now it should work, I'm intsalling the guest server..
