virtualbox

With VMWare it works fine and I can run multiple cores on a VMWare image. With Sun VirtualBox I can only run 1 cpu on a image. Its annoying.

Why does Sun Virtualbox not work the same as VMWare in this respect??

My CPU is:

XEON 3.00GHz Intel 90nm 2MBCache QUAD CPU x14 Socket 604 mPGA Family 15 Model 4(04) Stepping 3 Revision 05 MMX SSE3 XD

SIV.exe tells me:

No virtual machine extensions x86 with 64-bit support
NO IA64 support
MPS but with NO MCP
2 physical processors, 2 cores, 4 logical processors

There seems to be significant confusion about Hyper-Threading. Part of the problem is that vendors like to tout every new feature as the greatest invention since the six-pack, and its follow-on the 12-pack. I used to think the 4-pack was a travesty, but now that I am older and can nolonger finish… >>> More
