Expanding the Details section shows Result Code: NS_ERROR_FAILURE (0x80004005), Component: Console, Interface: IConsole {6375231a-c17c-464b-92cb-ae9e128d71c3}."" When trying this on OS X Snow Leopard with VBox 3.2, I get the following output in the console: >Oracle VM VirtualBox Command Line Management Interface Version 3.2.2 >(C) 2005-2010 Oracle Corporation >All rights reserved. > >Waiting for the VM to power on... >ERROR: Unknown error creating VM (VERR_PDM_DRVINS_UNKNOWN_CFG_VALUES) >Details: code NS_ERROR_FAILURE (0x80004005), component Console, interface IConsole, callee VBoxManage showvminfo ""vmname"" | grep -i nic returns the following, so it is able to parse the options: NIC 1: MAC: 0800274FE239, Attachment: NAT, Cable connected: on, Trace: on (file: /Users/me/nictrace1.pcap), Type: Am79C973, Reported speed: 0 Mbps Once I disable nictrace the vm is once again able to start just fine.
