headless debian - networkin doubts

[marmellata]

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.
VBox status code: -3100 (VERR_HOSTIF_INIT_FAILED)

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

[Sasquatch]

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.

Code: Select all

VBoxManage modifyvm <vmname> --bridgeadapter<1-N> none|<devicename>

Would become:

Code: Select all

VBoxManage modifyvm debian --nic1 bridged --bridgeadapter1 eth0

[marmellata]

VBoxManage modifyvm "server2" -nic1 hostif -hostifdev eth0

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..
