| 16 | The following fields are available on this wizard page:
|
|---|
| 17 | </p>
|
|---|
| 18 | <ul>
|
|---|
| 19 | <li>
|
|---|
| 20 | <p><b outputclass="bold">Base Memory.</b> Select the
|
|---|
| 21 | amount of RAM that Oracle VM VirtualBox should allocate every time
|
|---|
| 22 | the virtual machine is started. The amount of memory
|
|---|
| 23 | selected here will be taken away from your host machine and
|
|---|
| 24 | presented to the guest OS, which will report this size as
|
|---|
| 25 | the virtual machines installed RAM.
|
|---|
| 26 | </p>
|
|---|
| 27 | <note type="caution">
|
|---|
| 28 | <p>
|
|---|
| 29 | Choose this setting carefully. The memory you give to the
|
|---|
| 30 | VM will not be available to your host OS while the VM is
|
|---|
| 31 | running, so do not specify more than you can spare.
|
|---|
| 32 | </p>
|
|---|
| 33 | <p>
|
|---|
| 34 | For example, if your host machine has 4 GB of RAM and you
|
|---|
| 35 | enter 2048 MB as the amount of RAM for a particular
|
|---|
| 36 | virtual machine, you will only have 2 GB left for all the
|
|---|
| 37 | other software on your host while the VM is running. If
|
|---|
| 38 | you run two VMs at the same time, even more memory will be
|
|---|
| 39 | allocated for the second VM, which may not even be able to
|
|---|
| 40 | start if that memory is not available.
|
|---|
| 41 | </p>
|
|---|
| 42 | <p>
|
|---|
| 43 | On the other hand, you should specify as much as your
|
|---|
| 44 | guest OS and your applications will require to run
|
|---|
| 45 | properly. A guest OS may require at least 1 or 2 GB of
|
|---|
| 46 | memory to install and boot up. For best performance, more
|
|---|
| 47 | memory than that may be required.
|
|---|
| 48 | </p>
|
|---|
| 49 | </note>
|
|---|
| 50 | <p>
|
|---|
| 51 | Always ensure that the host OS has enough RAM remaining. If
|
|---|
| 52 | insufficient RAM remains, the system might excessively swap
|
|---|
| 53 | memory to the hard disk, which effectively brings the host
|
|---|
| 54 | system to a standstill.
|
|---|
| 55 | </p>
|
|---|
| 56 | <p>
|
|---|
| 57 | As with other <b outputclass="bold">Create Virtual
|
|---|
| 58 | Machine</b> wizard settings, you can change this
|
|---|
| 59 | setting later, after you have created the VM.
|

|
|---|
| 61 | </li>
|
|---|
| 62 | <li>
|
|---|
| 63 | <p><b outputclass="bold">Processor(s).</b> Select the
|
|---|
| 64 | number of virtual processors to assign to the VM.
|
|---|
| 65 | </p>
|
|---|
| 66 | <p>
|
|---|
| 67 | It is not advised to assign more than half of the total
|
|---|
| 68 | processor threads from the host machine.

|

| 70 | </li>
|

|

| 73 | Extensible Firware Interface (EFI) booting for the guest OS.
