Hey guys im pretty new to all of this just so you know but ill try and give you the most info i cant
I cant seem to get any virtual machine to run more than 1 core, it will say its using more but its clearly not (Lagging on some programs, no improvment when upping the amount of cores)
I have a 8350-fx, Using windows 8.1. My VM is windows xp.
Got 8 gigs of ram if that matters
I've went into my bios and found nothing to enable
My motherboard is an ECS A990FXM-A (V1.1).
IF only there was a way for me to get this working i would be one happy freaking camper, but right now this dreadful lag is making me a sad one.
Am i out of luck? AMD-V

Re: Am i out of luck? AMD-V
It's not likely your XP guest is lagging because it's only using one core. I've only used one core on all my guests and none of them lag. You may have too much or too little memory assigned to the guest. you may not have the guest additions installed. There are many reasons it could lag.
You should attach the vbox.log zipped.

It's lagging because of the program im running uses a decent amount of cpu, just a little more than 1 core provides me which is why i would be golden if i could just assign it one more dang core.

actually not if the program you are running can't utilize more than one core.guywithdowns wrote:It's lagging because of the program im running uses a decent amount of cpu, just a little more than 1 core provides me which is why i would be golden if i could just assign it one more dang core.
if it's only lagging with one program it's most unlikely because of having one core to work with.

I haven't used XP in years but in the XP device manager does it indicate it is using more than one core when you assign it more than one?

Yes, Lou, I have a few dual-processor XP guests running, and there are multiple processors shown in the Device Manager, one for each virtual CPU. Same with a Server 2003 and Windows 7 guests.

Re: Am i out of luck? AMD-V
Also, doesn't Windows 8.1 default to having hyper-v turned on? (I may be wrong...) If so, hyper-v would steal the AMD-V capabilities and keep anything else from using it, meaning Virtualbox couldn't get anymore than one processor in a guest. If this is the case, you can turn off hyper-v auto loading at boot, and Virtualbox would be able to use it.

on my Windows 8.1 guest, Hyper-V was turned off by default.
