That is good news. Glad to here the image works with ESXi! I've been thinking of adding in the PVSCSI support since ESXi supports this adapter.
 
Edit: Now that I think about it, PVSCSI is probably already built into the native image. I'll have to double check that.

I've been folding strickly in Windows ever since I started to fold but I wanted to give folding on Linux a try and this guide is freaking sweet! THX!

I'm using the virtualbox image, booting i7 with avx , but the configuration won't let me select/save the Sandy Bridge kernel option. What am I doing wrong? Or, should I just use the i7 kernel option?

Hmmmm, just rebooted and it did load the -avx kernel automatically, so I guess it's all good. The configuration just didn't keep the "Sandy Bridge" option selected as it does with the i7 option, but looks like it functions as it's supposed to.
 
So far the PPD is more than native Windows. I'm surprised that a VBox Nix guest under a Win7 host performs as well as it does, wish I'd read this thread earlier. Haven't gone through all 32 pages of this thread yet, but hoping I can optimize it further.
 
Sorry, haven't run the 2600K on native nix, but that does seem strange to me.

Just finished a P6099 and seems it doesn't want to upload. Any ideas? Or problems on Stanford's end?
 
Could it be related to the VBox network configuration? But, it was able to d/l the unit in the first place, and pings google fine, so I don't know.

Have you tried setting the network adapter for the VM to bridged? The default for Vbox is NAT and sometime can cause problems, bridged always works for me. Worth a try at least.

It could be a server issue or a firewall related issue somewhere on the network that is preventing access to those ports.

 
Well, I feel like an idiot.  The problem was my PeerBlock software. The host OS folds all day completing handshakes and downloading/uploading WU's, which is why I overlooked it. But PeerBlock apparently allows the VM to download a WU, but would not allow it to upload it back to Stanford. I don't understand why but I won't argue with success, everything is running fine now.

Over the past few months I received E-mail's from users of my images to add a few things including kernel builds for additional architectures, slapt-get Slackware package management tool, and thekraken developed by Tear. As such, I have made a few updates to my Virtualbox image so far with the following.
 
+ Built kernel 3.4.4 for the following CPU types using GCC 4.7 and binutils 2.22:
    Intel: Core 2, Nehalem, Sandy Bridge, Ivy Bridge, Haswell AMD: Barcelona, Bulldozer, Piledriver
+ Added slapt-get 13.37 and dependencies and set to source off a slackware64-current mirror.
+ Updated Tear's Langouste and TheKraken tools to the latest versions available.
    Langouste: 0.15.7, TheKraken: 0.17-pre15
+ Installed VirtualBox Additions 4.1.18
 

I do not have all these different processor types so I cannot say for sure what if any difference building the kernel for specific architectures will help with folding. I also received a request to attempt to build the kernel with AMD's compiler for Bulldozer. I have not had a chance to look into that yet but it seems like an interesting project that I would like to look into.
 
Testing with Virtualbox 4.1.18, I am seeing near the same performance as running in native Linux.
 
P7506 - 3930K @ 4.25 GHz - smp 12
Virtualbox: 2:08
Native: 2:05
 
This new version of Virtualbox appears to have some delay with ACPI shutdown. If you see a delay on reboot or shutdown, I think it might have to do with this new version.

That was with the same build. I still have to  update my native installer which I hope to do soon. I will basically copy what is setup for VB but then build the kernels with the necessary SATA/SAS and Ethernet support to cover different motherboard types.

Double post I know...
 
Would the Barcelona option be the choice for any K10 (Phenom II, Opteron 61xx etc) based CPU? I'd guess so, but I'm unable to test this right now.

Here is where I am. I'm wanting to setup folding on a SR2 with CPU's E5645 & E5620 20 cores.
 
What would be best to use for this in the OS of Windows 7 64bit Virtualbox 4.1.18 or
something else & what image should I use?
Links would be a great help. Some of the links on 1st page don't seem to work for me at this time.
Been a while since I done a VM so I may need some help a long the way.
Thanks

If you plan to run GPU folding or need Windows OS for running other apps, the Virtualbox image should work good and from my testing is close to performance of folding in standalone Linux.

Here is a link to my latest Virtualbox image:

Virtualbox 1.5.0 image

The Internet connection to my server is unfortunately not the best so there may occasionally be an issue accessing the site.

First off: Thanks for your wonderful thread and hard work.
I have it pretty much worked out now, but you can look at my progress here and make suggestion if you see anything I could do to make it any better.
Thanks again great work.
