8 VBoxManage • createdirectory, which allows copying files from the host to the guest (only with in- stalled Guest Additions 4.0 and later). VBoxManage createdir[ectory]|mkdir|md vmname|uuid directory to create on guest [--username "name"] [--password "password"] [--parents] [--mode mode] [--verbose] where the parameters mean: uuid|vmname The VM UUID or VM name. Mandatory. directory to create on guest Absolute path of directory/directories to create on guest, e.g. D:\Foo\Bar. Parent directories need to exist (e.g. in this example D:\Foo) when switch --parents is omitted. The specified user must have appropriate rights to create the specified directory. –username name Name of the user the copy process should run under. This user must exist on the guest OS. –password password Password of the user account specified with --username. If not given, an empty password is assumed. –parents Also creates not yet existing parent directories of the specified directory, e.g. if the directory D:\Foo of D:\Foo\Bar does not exist yet it will be created. Without specifying --parent the action would have failed. –mode mode Sets the permission mode of the specified directory. Only octal modes (e.g. 0755) are supported right now. –verbose Tells VBoxManage to be more verbose. • updateadditions, which allows for updating an already installed Guest Additions version on the guest (only already installed Guest Additions 4.0 and later). VBoxManage guestcontrol updateadditions vmname|uuid [--source "guest additions .ISO file to use"] [--verbose] where the parameters mean: uuid|vmname The VM UUID or VM name. Mandatory. –source “guest additions .ISO file to use“ Full path to an alternative VirtualBox Guest Additions .ISO file to use for the Guest Additions update. –verbose Tells VBoxManage to be more verbose. 8.30 VBoxManage debugvm The “debugvm” commands are for experts who want to tinker with the exact details of virtual machine execution. Like the VM debugger described in chapter 12.1.3, The built-in VM debugger, page 165, these commands are only useful if you are very familiar with the details of the PC architecture and how to debug software. The subcommands of “debugvm” all operate on a running virtual machine. The following are available: • With dumpguestcore --filename name, you can create a system dump of the running VM, which will be written into the given file. This file will have the standard ELF core format (with custom sections) see chapter 12.1.4, VM core format, page 167. This corresponds to the writecore command in the debugger. • The info command is used to display info items relating to the VMM, device emulations and associated drivers. This command takes one or two arguments: the name of the info item, optionally followed by a string containing arguments specific to the info item. The 129
