Tabla de contenidos 1.The most important thing to add is the template (newstudent or newteacher)and the full name of your user (see image).As you follow the wizard, you will see that GOsa² generates a usernameautomatically based on the real name. It automatically chooses a usernamethat doesn't exist yet, so multiple users with the same full name are not aproblem. Note that GOsa² can generate invalid usernames if the full namecontains non-ASCII characters.If you don't like the generated username you can select another usernameoffered in the drop-down box, but you do not have a free choice here in thewizard. (If you want to be able to edit the proposed username, open/etc/gosa/gosa.conf with an editor and addallowUIDProposalModification='true' as anadditional option to the 'location definition'.).When the wizard has finished, you are presented with the GOsa² screen foryour new user object. Use the tabs at the top to check the completed fields.After you have created the user (no need to customise fields the wizard hasleft empty for now), click on the 'Ok' button in the bottom-right corner.As the last step GOsa² will ask for a password for the new user.
Type thatin twice and then click 'Set password' in the bottom-right corner. Some characters may not be allowed as part of the password.If all went well, you can now see the new user in the user list table. Youshould now be able to log in with that username on any Skolelinux machinewithin your network.

Table of ContentsWelcome to Oracle VM VirtualBox.Oracle VM VirtualBox is a cross-platform virtualization application. Whatdoes that mean? For one thing, it installs on your existing Intel orAMD-based computers, whether they are running Windows, Mac OS X,Linux, or Oracle Solaris operating systems (OSes). Secondly, itextends the capabilities of your existing computer so that it canrun multiple OSes, inside multiple virtual machines, at the sametime. As an example, you can run Windows and Linux on your Mac, runWindows Server 2016 on your Linux server, run Linux on your WindowsPC, and so on, all alongside your existing applications.
You caninstall and run as many virtual machines as you like. The onlypractical limits are disk space and memory.Oracle VM VirtualBox is deceptively simple yet also very powerful. It canrun everywhere from small embedded systems or desktop class machinesall the way up to datacenter deployments and even Cloudenvironments.The following screenshot shows how Oracle VM VirtualBox, installed on anApple Mac OS X computer, is running Windows Server 2016 in a virtualmachine window. In this User Manual, we will begin simply with a quick introductionto virtualization and how to get your first virtual machine runningwith the easy-to-use Oracle VM VirtualBox graphical user interface.Subsequent chapters will go into much more detail covering morepowerful tools and features, but fortunately, it is not necessary toread the entire User Manual before you can use Oracle VM VirtualBox.You can find a summary of Oracle VM VirtualBox's capabilities in. For existing Oracle VM VirtualBoxusers who just want to find out what is new in this release, see the.Running multiple operating systemssimultaneously. Oracle VM VirtualBox enables you to runmore than one OS at a time. This way, you can run softwarewritten for one OS on another, such as Windows software onLinux or a Mac, without having to reboot to use it.

Since youcan configure what kinds of virtualhardware should be presented to each such OS, you can installan old OS such as DOS or OS/2 even if your real computer'shardware is no longer supported by that OS.Easier softwareinstallations. Software vendors can use virtualmachines to ship entire software configurations. For example,installing a complete mail server solution on a real machinecan be a tedious task. With Oracle VM VirtualBox, such a complexsetup, often called an appliance, can bepacked into a virtual machine.
Installing and running a mailserver becomes as easy as importing such an appliance intoOracle VM VirtualBox.Testing and disasterrecovery. Once installed, a virtual machine and itsvirtual hard disks can be considered acontainer that can be arbitrarily frozen,woken up, copied, backed up, and transported between hosts.On top of that, with the use of another Oracle VM VirtualBox featurecalled snapshots, one can save aparticular state of a virtual machine and revert back to thatstate, if necessary. This way, one can freely experiment witha computing environment. If something goes wrong, such asprolems after installing software or infecting the guest witha virus, you can easily switch back to a previous snapshot andavoid the need of frequent backups and restores.Any number of snapshots can be created, allowing you to travelback and forward in virtual machine time. You can deletesnapshots while a VM is running to reclaim disk space.Infrastructure consolidation.Virtualization can significantly reduce hardware andelectricity costs. Most of the time, computers today only usea fraction of their potential power and run with low averagesystem loads. A lot of hardware resources as well aselectricity is thereby wasted.

So, instead of running manysuch physical computers that are only partially used, one canpack many virtual machines onto a few powerful hosts andbalance the loads between them.Host operating system (hostOS). This is the OS of the physical computer onwhich Oracle VM VirtualBox was installed. There are versions ofOracle VM VirtualBox for Windows, Mac OS X, Linux, and OracleSolaris hosts. See.Most of the time, this manual discusses all Oracle VM VirtualBoxversions together. There may be platform-specific differenceswhich we will point out where appropriate.Guest operating system (guestOS).
This is the OS that is running inside thevirtual machine. Theoretically, Oracle VM VirtualBox can run any x86OS such as DOS, Windows, OS/2, FreeBSD, and OpenBSD. But toachieve near-native performance of the guest code on yourmachine, we had to go through a lot of optimizations that arespecific to certain OSes. So while your favorite OSmay run as a guest, we officially supportand optimize for a select few, which include the most commonOSes.See.Virtual machine (VM). Thisis the special environment that Oracle VM VirtualBox creates foryour guest OS while it is running. In other words, you runyour guest OS in a VM. Normally, a VM isshown as a window on your computer's desktop.
Depending onwhich of the various frontends of Oracle VM VirtualBox you use, theVM might be shown in full screen mode or remotely on anothercomputer.Internally, Oracle VM VirtualBox treats a VM as a set of parametersthat specify its behavior. Some parameters describe hardwaresettings, such as the amount of memory and number of CPUsassigned. Other parameters describe the state information,such as whether the VM is running or saved.You can view these VM settings in the VirtualBox Managerwindow, the Settings dialog,and by running the VBoxManage command. See.Guest Additions. Thisrefers to special software packages which are shipped withOracle VM VirtualBox but designed to be installedinside a VM to improve performance of theguest OS and to add extra features. Oracle VM VirtualBoxruns on a large number of 64-bit host operating systems.
See.Oracle VM VirtualBox is a so-called hostedhypervisor, sometimes referred to as a type2 hypervisor. Whereas abare-metal or type 1hypervisor would run directly on the hardware, Oracle VM VirtualBoxrequires an existing OS to be installed. It can thus runalongside existing applications on that host.To a very large degree, Oracle VM VirtualBox is functionallyidentical on all of the host platforms, and the same file andimage formats are used. This enables you to run virtualmachines created on one host on another host with a differenthost OS. For example, you can create a virtual machine onWindows and then run it under Linux.In addition, virtual machines can easily be imported andexported using the Open Virtualization Format (OVF), anindustry standard created for this purpose. You can evenimport OVFs that were created with a different virtualizationsoftware.
See.For users of Oracle Cloud Infrastructure the functionality extends to exporting andimporting virtual machines to and from the cloud. Thissimplifies development of applications and deployment to theproduction environment. See.Guest Additions: shared folders,seamless windows, 3D virtualization.
TheOracle VM VirtualBox Guest Additions are software packages which canbe installed inside of supported guestsystems to improve their performance and to provide additionalintegration and communication with the host system. Afterinstalling the Guest Additions, a virtual machine will supportautomatic adjustment of video resolutions, seamless windows,accelerated 3D graphics and more. See.In particular, Guest Additions provide for sharedfolders, which let you access files on the hostsystem from within a guest machine. See.Great hardware support.
Amongother features, Oracle VM VirtualBox supports the following.Guest multiprocessing(SMP). Oracle VM VirtualBox can present up to 32virtual CPUs to each virtual machine, irrespective of howmany CPU cores are physically present on your host.USB device support.Oracle VM VirtualBox implements a virtual USB controller andenables you to connect arbitrary USB devices to yourvirtual machines without having to install device-specificdrivers on the host.
USB support is not limited to certaindevice categories. See.Hardware compatibility.Oracle VM VirtualBox virtualizes a vast array of virtualdevices, among them many devices that are typicallyprovided by other virtualization platforms.
That includesIDE, SCSI, and SATA hard disk controllers, several virtualnetwork cards and sound cards, virtual serial and parallelports and an Input/Output Advanced Programmable InterruptController (I/O APIC), which is found in many computersystems. This enables easy cloning of disk images fromreal machines and importing of third-party virtualmachines into Oracle VM VirtualBox.Full ACPI support. TheAdvanced Configuration and Power Interface (ACPI) is fullysupported by Oracle VM VirtualBox. This enables easy cloning ofdisk images from real machines or third-party virtualmachines into Oracle VM VirtualBox. With its uniqueACPI power status support,Oracle VM VirtualBox can even report to ACPI-aware guest OSesthe power status of the host.
For mobile systems runningon battery, the guest can thus enable energy saving andnotify the user of the remaining power, for example infull screen modes.Multiscreen resolutions.Oracle VM VirtualBox virtual machines support screen resolutionsmany times that of a physical screen, allowing them to bespread over a large number of screens attached to the hostsystem.Built-in iSCSI support.This unique feature enables you to connect a virtualmachine directly to an iSCSI storage server without goingthrough the host system. The VM accesses the iSCSI targetdirectly without the extra overhead that is required forvirtualizing hard disks in container files.
See.PXE Network boot. Theintegrated virtual network cards of Oracle VM VirtualBox fullysupport remote booting using the Preboot ExecutionEnvironment (PXE).Multigeneration branchedsnapshots. Oracle VM VirtualBox can save arbitrarysnapshots of the state of the virtual machine. You can go backin time and revert the virtual machine to any such snapshotand start an alternative VM configuration from there,effectively creating a whole snapshot tree. You can create and deletesnapshots while the virtual machine is running.VM groups. Oracle VM VirtualBoxprovides a groups feature that enables the user to organizeand control virtual machines collectively, as well asindividually. In addition to basic groups, it is also possiblefor any VM to be in more than one group, and for groups to benested in a hierarchy.
This means you can have groups ofgroups. In general, the operations that can be performed ongroups are the same as those that can be applied to individualVMs: Start, Pause, Reset, Close (Save state, Send Shutdown,Poweroff), Discard Saved State, Show in File System, Sort.Clean architecture and unprecedentedmodularity. Oracle VM VirtualBox has an extremely modulardesign with well-defined internal programming interfaces and aclean separation of client and server code.
This makes it easyto control it from several interfaces at once. For example,you can start a VM simply by clicking on a button in theOracle VM VirtualBox graphical user interface and then control thatmachine from the command line, or even remotely. See.Due to its modular architecture, Oracle VM VirtualBox can alsoexpose its full functionality and configurability through acomprehensive software development kit(SDK), which enables integration of Oracle VM VirtualBoxwith other software systems. See.Remote machine display. TheVirtualBox Remote Desktop Extension (VRDE) enableshigh-performance remote access to any running virtual machine.This extension supports the Remote Desktop Protocol (RDP)originally built into Microsoft Windows, with specialadditions for full client USB support.The VRDE does not rely on the RDP server that is built intoMicrosoft Windows. Instead, the VRDE is plugged directly intothe virtualization layer.
As a result, it works with guestOSes other than Windows, even in text mode, and does notrequire application support in the virtual machine either.
