I rebooted my machine, and - oops - the file was back to a version about 2 weeks ago!!! This would also ease the implementation of the enhancement ticket i just filed Also it seems that if during creation of a snapshot an ISO image is mounted, and the ISO is removed from disk afterwards, the media registry refuses to remove the file from the registry - seems like a snapshot wanting this file locks it somehow Replying to mduft :.
Log files are in a subfolder called Logs , and if you have taken snapshots, they are in a Snapshots subfolder. For each VM, you can change the location of its snapshots folder in the VM settings. Then, in the displayed window, click on the General tab. Alternatively, use the VBoxManage setproperty machinefolder command. See Section 8. In addition to the files for the virtual machines, Oracle VM VirtualBox maintains global configuration data in the following directory:.
Oracle VM VirtualBox creates this configuration directory automatically, if necessary. Since the global VirtualBox. This file includes global configuration options and a list of registered virtual machines with pointers to their XML settings files. The following table gives a brief overview of the configuration data locations on an Oracle VM VirtualBox host. Media registration is done automatically when a storage medium is attached to a VM.
When a new settings file is created, for example because a new virtual machine is created, Oracle VM VirtualBox automatically uses the settings format of the current Oracle VM VirtualBox version.
However, when Oracle VM VirtualBox encounters a settings file from an earlier version, such as after upgrading Oracle VM VirtualBox, it attempts to preserve the settings format as much as possible. It will only silently upgrade the settings format if the current settings cannot be expressed in the old format, for example because you enabled a feature that was not present in an earlier version of Oracle VM VirtualBox.
In such cases, Oracle VM VirtualBox backs up the old settings file in the virtual machine's configuration directory. If you need to go back to the earlier version of Oracle VM VirtualBox, then you will need to manually copy these backup files back.
We therefore strongly suggest that you do not edit these files manually. Oracle VM VirtualBox was designed to be modular and flexible. This process is started automatically by the first Oracle VM VirtualBox client process and exits a short time after the last client exits.
The service is responsible for bookkeeping, maintaining the state of all VMs, and for providing communication between Oracle VM VirtualBox components. When we refer to clients here, we mean the local clients of a particular VBoxSVC server process, not clients in a network.
When started without the --startvm option, this application acts as the VirtualBox Manager, displaying the VMs and their settings. If the VirtualBoxVM client application is started with the --startvm argument, it loads the VMM library which includes the actual hypervisor and then runs a virtual machine and provides the input and output for the guest.
Any Oracle VM VirtualBox front-end, or client, will communicate with the service process and can both control and reflect the current state. VBoxManage : A less user-friendly but more powerful alternative. See Chapter 8, VBoxManage. See Section 7. This is also described in the SDK reference. These include the following:. IPRT: A portable runtime library which abstracts file access, threading, and string manipulation. Whenever Oracle VM VirtualBox accesses host operating features, it does so through this library for cross-platform portability.
This component also enables remote USB. Oracle VM VirtualBox emulates a number of devices to provide the hardware environment that various guests need. Use Vboxmanage to edit the guests available. See the manual, section 8. The best way to supply guests if you are still going to use them in Virtualbox is with a guest folder copy.
Also good for "Backing Up a VM". Students are quick to complain when things take too long. I'm not editing the. FWIW, you can register a new guest by double-clicking the. Or you can use Vboxmanage in a batch file and provide a shortcut to the script.
Or even a shortcut to the. If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones. Come back soon for an in-depth tutorial on upgrading an existing VirtualBox installation, tuning it for maximum performance and importing previous Guest OS installations.
