Virtualbox problem!

[Roasted Bunny]

Hey. I want to add more CPU cores into a virtual machine,and I tried that and I still get 100% CPU usage on my vm and around 10 or 20 on the host. I really want higher performance. Thanks!

What are you trying to do in your VM to get 100% cpu usage? What is the host OS and the VM OS?

Just standard stuff. Downloading programs watching videos etc. Windows XP most of the time, and some other ones too. I have Windows 7 professional 64 bit on my host.

Hmmm, what programs are running in your VM background to reach 100%?

I can't remember exactly. The payload isn't high for sure. Very light programs.

Well if you know 100% of your CPU is used then the task manager should show you which programs are causing that X)

What CPU do you have?

CPU: Intel Core i7 950 @ 3.07GHz (NOT overclocked) Bloomfield 45nm Technology

Core2Duo and newer cpu's from Intel (all i-series cpus) have VIRTUALIZATION support in the hardware - turn it on in the bios if it isn't already on for better performance. Make sure to have atleast 6gb of ram in your HOST system and 2gb of ram for XP. More than 3 or 3.5gb of ram on the emulated XP machine would be a waste. Other names for the virtualization feature include V2D or VTD feature. It's usually in your cpu options pane of the BIOS screen (not usually the overclocking pane). Look in your motherboard manual for advanced system features.
More GHZ on the host pc = more speed with the client machine.
You are also running your system in IDE mode, which can slow down as there's no hardware support for command que'ing. Please remember to switch bios to SATA/AHCI mode in your Marvell or Intel ICH10 chipset NEXT TIME YOU GO TO RE-INSTALL WINDOWS 7/8/10 on your main machine. Windows installed to IDE mode drives will REFUSE TO BOOT (until you switch it back).
AHCI SATA mode will enabled better drive performance (especially for SSD's) with support for ACQ - advanced command que, which lets the drive work more thoroughly without hanging the system. Don't ever use IDE unless it's for XP or something old.

On another note: Bad drivers may cause an issue if you have 2+ gb of ram on your emulated machine if you have buggy drivers - keep this in mind if you get weird errors with more than 2gb allocated to the XP machine.

I agree with the post above, virtualization must be off, i have a very good performance on my i5-3330, even my lap (i7-4500U 15w) does a very good job with virtualization enabled
