How can I get the Bridged IP address of a VirtualBox VM running in headless mode?

I have VirtualBox set up on a server. It was set up as a Bridged VM, and has an IP address. It's now running in headless mode, started with "VBoxHeadless -s PuppetMaster".

How can I find out what IP the VM is using VBoxManage?

• Not sure if VBoxManage can give you that information directly. What you can do is run the following command to see the network card configuration.

  VBoxManage showvminfo PuppetMaster | egrep ^NIC
  

  That will if nothing else will provide you with the MAC address, allowing you to find out the actual ip address by other means.

  Jonathan Haddad : Any ideas on how to get the IP using the MAC address from the command line?

• I could find my Headless VB with the combination of following commands:

  # Update arp table
  for i in {1..254}; do ping -c 1 192.168.178.$i & done
  
  # Find vm name
  VBoxManage list runningvms
  
  # Find MAC: subsitute vmname with your vm's name
  VBoxManage showvminfo vmname
  
  # Find IP: substitute vname-mac-addr with your vm's mac address in ':' notation
  arp -a | grep vmname-mac-addr
  

  But even easier: in linux, you can connect to the VB:

  # Default VirtualBox Listening Port: 3389
  rdesktop -N hostingserver:3389
  

  This command will open a shell window, and you'll have direct access to the Headless VB, where you can retrieve your Headless VB IP: ip addr
