VirtualBox Performance

I was wondering if it's just me or if everyone has the same Problem, but I'm getting very poor performance with VM's on my OMV system. Especially graphics are choppy, Linux/Windows guest, doesn't matter. It also doesn't yield a huge performance boost if I allocate 2GB or more RAM to a guest OS.

Specs are:
CPU: AMD Athlon 64 X2 5200+ (2.7Ghz)
RAM: 4GB DDR-2
GPU: Geforce 8500 GT 512MB (not sure if this actually gets used)
and variouse HDD's

Thats my old Desktop setup where I've been running VM's under Win7 just fine, which is wierd because OMV has a much lower footprint than Win7. I just like to know if that is "normal" or if my plugin/configuration is broken in some way ? Maybe someone can shed some light in this matter.

do you know if your CPU has the VT extensions etc?
i know my little atom and unfortunately my laptop don't have either so Vm's are always poor

Yep, pretty sure it does. If I remember correctly VT is needed to run 64bit guest, which I do.

Graphics card drivers.....possible. Is there a package I can just install ?

lsmod | grep nouveau shows this.

Edit: connecting via rdp, allocated 256mb memory, but it doesn't seem to make a difference if I allocate less.

OMV has the default partition layout, if I remember correctly the default swap partition was around 256-512MB.

VM is not on the same hard drive although spec wise nothing has changed, before it was on a WD 2TB and now it is on a Hitachi 2TB.

Yes I'm on 64bit OMV. As I've said, the hardware is from my old Desktop system which ran Win7 and Virtualbox (linux and windows guest) with no problems at all. That's why I was surprised about the poor/choppy performance.

I've tried different versions of Win7 and some Linux distros, it's the same thing for every VM. The last thing I tried was making the vdisk size fixed, but that didn't do any good either.

Did you connect to the VMs over rdp when it was on the desktop?

No.

Guest Additions are Installed. The Hitachi drive is probably a year old maybe even less.
