| 8 | To provide SSE 4.1/SSE 4.2 support to guests, the host CPU has to
|
|---|
| 9 | implement these instruction sets. The instruction sets are exposed
|
|---|
| 10 | to guests by default, but it is possible to disable the
|
|---|
| 11 | instructions for certain guests by using the following commands:
|

|

| 13 | <pre xml:space="preserve">$ VBoxManage setextradata <varname>VM-name</varname> \
|
|---|
| 14 | VBoxInternal/CPUM/IsaExts/SSE4.1 0
|
|---|
| 15 | $ VBoxManage setextradata <varname>VM-name</varname> \
|
|---|
| 16 | VBoxInternal/CPUM/IsaExts/SSE4.2 0</pre>
|
|---|
| 17 | <p>
|
|---|
| 18 | These are per-VM settings which are enabled by default.
