8 VBoxManage • bridgedifs, hostonlyifs and dhcpservers, respectively, list bridged network interfaces, host-only network interfaces and DHCP servers currently available on the host. Please see chapter 6, Virtual networking, page 83 for details on these. • hostinfo displays information about the host system, such as CPUs, memory size and operating system version. • hostcpuids dumps the CPUID parameters for the host CPUs. This can be used for a more fine grained analyis of the host’s virtualization capabilities. • hddbackends lists all known virtual disk back-ends of VirtualBox. For each such format (such as VDI, VMDK or RAW), this lists the back-end’s capabilities and configuration. • hdds, dvds and floppies all give you information about virtual disk images currently in use by VirtualBox, including all their settings, the unique identifiers (UUIDs) associated with them by VirtualBox and all files associated with them. This is the command-line equivalent of the Virtual Media Manager see chapter 5.3, The Virtual Media Manager, page 74. • usbhost supplies information about USB devices attached to the host, notably information useful for constructing USB filters and whether they are currently in use by the host. • usbfilters lists all global USB filters registered with VirtualBox – that is, filters for devices which are accessible to all virtual machines – and displays the filter parameters. • systemproperties displays some global VirtualBox settings, such as minimum and maxi- mum guest RAM and virtual hard disk size, folder settings and the current authentication library in use. • extpacks displays all VirtualBox extension packs currently installed see chapter 1.5, In- stalling VirtualBox and extension packs, page 14 and chapter 8.34, VBoxManage extpack, page 133 for more information. 8.4 VBoxManage showvminfo The showvminfo command shows information about a particular virtual machine. This is the same information as VBoxManage list vms --long would show for all virtual machines. You will get information similar to the following: $ VBoxManage showvminfo "Windows XP" VirtualBox Command Line Management Interface Version 4.0.4 (C) 2005-2011 Oracle Corporation All rights reserved.
