Best processor for Virtualization?

I am a mobile apps developer and its useful to run a virtual machine. Is it safe to assume that a six core processor and 8gb RAM can make two vms and the host run at near full speed?

"near full speed" is the catch - as long as you match settings to what your cpu is capable of and regard the lack of 3d support (for the most part)
i've had the best performance with virtualbox, but i like the wdm 3d driver that vmware provides for full aero support in vista and 7.

iether way my 7.8/7.9 wei rig will get about 6.6-7.1 when running the host (windows 7 64) and two or three vms:
windows 7, windows XP and a linux distro

allowing each os about 2gb and 1 or 2 processors each

this is all running the rig in my sig

i'd say go with the quad as long as it supports vt - it made a big impact on processing performance, which i assume would be important if your constantly compiling and running. theres more processing power in this solution and you can spit up your proc amongst the vms they way you want to instead of sharing full time with the host.

It all depends on how many VM's you plan on running on the host server. If you're running just one VM on a host machine, a quad core host machine would be more than enough, with at least 4gb RAM. Of course this all varies depending on what your VM will be (OS) and what it will be doing. If your apps will be single threaded, i'd actually recommend fewer, faster cores.

i thought you were talking about desktop quad cores, the difference now is a lot less now that your talking about notebook hardware, where intel will give you the edge if you split the cores due to their faster architecture... you can go either way at those clock speeds - i'd say go for personal preference especially if the i5 has ht (though i don't think the notebook ones have. i'd still lean towards having more cores, theres less likely a chance the system will hang at times some cores are being used because theres obviously going to be more free cores

(sory it took so long to respond, toms email feature, among other features, is not working right now so i had to search for this thread)

let us know what solution came about for you and your satisfaction level with the new comp. it'd be interesting to know how it worked out for you

Hmmm looks like my last post didn't actually post. Okay well I decided to go with a Toshiba Satellite A665-S6094. Core i7 740QM processor, I think. Quad core. Awesome sound package which is a simple bonus lol. Came with 4GB ram but I replaced it all with a GSkill 8GB kit at PC10600 which is the fastest ram this machine can handle. I am pleased to announce that I am able to run my Ubuntu host and my Windows 7 guest, Windows XP guest AND Mac OS X Snow Leopard guest. Concurrently. All at the same time. Obviously there are some slow downs and I really don't need to run ALL at the same time. But this is perfect as an applications developer. Ubuntu works great for Android, Windows will be good if I decide to go Windows Phone 7 and when I decide to take the plunge into iPhone development I'm golden. I just set each VM to a seperate virtual desktop in Ubuntu and it is easy to switch. Definitely happy with this machine and processor/memory combo.
