I've read that VirtualBox doesn't have the ability to use more than one core of a multi-core chip for the Guest VM, but that SMP support for Guests was planned (see this thread). Is there any information as to status of this feature?

I did find an option under ~/.VirtualBox/Machines/NAME_OF_VM/NAME_OF_VM.xml called "CPU count" but changing it from "1" to "4" had no effect

Code: Select all

    <Hardware>
      <CPU count="4">
        <HardwareVirtEx enabled="true"/>
        <HardwareVirtExNestedPaging enabled="true"/>
        <PAE enabled="true"/>
      </CPU>

From what I hear they are still working on it but it is not here yet. As you can imagine there are a lot of road blocks to work out first.

That part of the XML file was already added a few versions back. It's a preparation for when SMP is added. It's probably not stable enough or any benefit to the overal performance of the VM. This was already noted here on the forums when it was added, so you're not bringing anything new
