In addition, you can use the following actions for DB instance class processor information: Valid names are coreCount and threadsPerCore.
VirtualBox extension packages have a.
To install an extension, simply double-click on the package file and a Network Operations Manager window will appear, guiding you through the required steps.
To view the extension packs that are currently installed, please start the VirtualBox Manager see the next section. From the "File" menu, please select "Preferences". In the window that shows up, go to the "Extensions" category which shows you the extensions which are currently installed and allows you to remove a package or add a new one.
Alternatively you can use VBoxManage on the command line: On a Windows host, in the standard "Programs" menu, click on the item in the "VirtualBox" group. You may want to drag this item onto your Dock. On a Linux or Solaris host, depending on your desktop environment, a "VirtualBox" item may have been placed in either the "System" or "System Tools" group of your "Applications" menu.
Alternatively, you can type VirtualBox in a terminal.
When you start VirtualBox for the first time, a window like the following should come up: This window is called the "VirtualBox Manager". On the left, you can see a pane that will later list all your virtual machines. Since you have not created any, the list is empty. A row of buttons above it allows you to create new VMs and work on existing VMs, once you have some.
The pane on the right displays the properties of the virtual machine currently selected, if any. Again, since you don't have any machines yet, the pane displays a welcome message.
To give you an idea what VirtualBox might look like later, after you have created many machines, here's another example: Creating your first virtual machine Click on the "New" button at the top of the VirtualBox Manager window. A wizard will pop up to guide you through setting up a new virtual machine VM: On the following pages, the wizard will ask you for the bare minimum of information that is needed to create a VM, in particular: For "Operating System Type", select the operating system that you want to install later.
The supported operating systems are grouped; if you want to install something very unusual that is not listed, select "Other". Depending on your selection, VirtualBox will enable or disable certain VM settings that your guest operating system may require.
It is therefore recommended to always set it to the correct value. On the next page, select the memory RAM that VirtualBox should allocate every time the virtual machine is started.
The amount of memory given here will be taken away from your host machine and presented to the guest operating system, which will report this size as the virtual computer's installed RAM.
Note Choose this setting carefully! The memory you give to the VM will not be available to your host OS while the VM is running, so do not specify more than you can spare.
If you run two VMs at the same time, even more memory will be allocated for the second VM which may not even be able to start if that memory is not available.
On the other hand, you should specify as much as your guest OS and your applications will require to run properly. Of course, if you want to run graphics-intensive applications in your VM, you may require even more RAM.
But, in any case, make sure you always have at least to MB of RAM left on your host operating system. Otherwise you may cause your host OS to excessively swap out memory to your hard disk, effectively bringing your host system to a standstill.
As with the other settings, you can change this setting later, after you have created the VM. Next, you must specify a virtual hard disk for your VM.
This file represents an entire hard disk then, so you can even copy it to another host and use it with another VirtualBox installation. The wizard shows you the following window: Here you have the following options: To create a new, empty virtual hard disk, press the "New" button.
You can pick an existing disk image file. The drop-down list presented in the window contains all disk images which are currently remembered by VirtualBox, probably because they are currently attached to a virtual machine or have been in the past.
Alternatively, you can click on the small folder button next to the drop-down list to bring up a standard file dialog, which allows you to pick any disk image file on your host disk.PISA AND THE DEFINITION OF KEY COMPETENCIES In , OECD member countries launched the Programme for International Student Assessment (PISA), with the aim of monitoring the extent to which students near the end of.
