Ahem, virtualization = VMWare? Strange, I thought Amazon is using Xen? Anyway, I do. And here is my shortlist: Hypervisor: Xen 4.3 Host OS / dom0: Linux Mint 16 VM: Windows 7 Pro 64bit with VGA passthrough The short answer to "why?": Convenience, stability, security. The long answer: I...

I'm running Xen 4.3 on Linux Mint 16 (Ubuntu 13.10) using the "xm" toolstack. No patches, no nothing. Should work for your hardware too. Here is my how-to, if you are interested: HOW-TO make dual-boot obsolete using XEN VGA passthrough. Some people have done exactly what you are planning to do...

For those who know what VT-d is good for, here's my BIOS upgrade experience (if you run Windows, don't read any further): Hardware: Asus Sabertooth X79 BIOS release before update: 1203 (yes, that ancient one from mid-2012) BIOS release when converting ROM to CAP: 2104 BIOS release after latest...

I got my Sabertooth X79 in April 2012, so if you bought recently they may ship with newer drivers. Here is what I could make out. In MB SUPPORT CD/Drivers/Audio/Driver/Vista64/HDX*.inf and /Vista/HDX*.inf files: [Strings] MfgName="Realtek" ; not sure if this is localizable...

@ OP: Any response from Asus via Raja ?

Dear virtualization user: I'm looking for reliable information on AMD-V (IOMMU) support in motherboards to help select compatible hardware. As you may know, vendor information on this particular topic is often incomplete, or unreliable. If you are using Xen, KVM, VMware, or Hyper-V with IOMMU...

Dear virtualization user: I'm looking for reliable information on VT-d support in motherboards to help select compatible hardware. As you may know, vendor information on this particular topic is often incomplete, or unreliable. If you are using Xen, KVM, VMware, or Hyper-V with VT-d enabled...

See if this post and the links there provide answers: http://hardforum.com/showpost.php?p=1039930815&postcount=8 I'm not familiar with TF2 idling. GPU/VGA passthru uses one dedicated GPU per VM. For VGA passthru to work you need specific hardware that supports VT-d (Intel) or IOMMU / AMD-Vi...

I use Xen and have a Nvidia Quadro 2000 passed through to a Win 7 guest. The "multiOS" Nvidia cards should work, but they are expensive. For Xen there are patches for some non-multiOS Nvidia cards to allow passthrough. Some other Nvidia cards are also reported to work out of the box. Using KVM...

I am using the FREE Xen hypervisor, not the commercial Xenserver Enterprise. VMware has lately also introduced GPU passthrough, so that should be an option. You'll need VT-d (IOMMU) compatible hardware for passthrough to work. Sticking with AMD graphics for GPU passthrough should help, but...

Yep, the SKY 900 looks like a good solution. My 2c on virtualization and graphics: I use a Xen hypervisor with PCI and VGA passthrough to have a Windows guest run about as good as if it was installed on bare metal. It uses its own Quadro 2000 card. Nvidia is usually tricky or next to...

You posted the link: http://meadowcourt.org/downloads/ :)

I use one per guest, but using one card for multiple guests should be doable, but I don't know how exactly. I actually wonder how you are going to use the AMD card you got for multiple guests? Are you currently able to use the AMD card to render pictures and then stream them to a remote...

Interesting thread. The Passmark result seems a little low, unless you assigned only ~2-3 VCPUs to your Windows guest. About graphics cards: Your AMD card gives you the option to try a Xen hypervisor (or KVM) with VGA passthrough. Nvidia cards won't work, unless you buy the very expensive...

Have you ever tried Xen? I can't say much about KVM as I never tried it since it lacked some features I needed. I've found Xen to be quite easy to work with, though my primary use of it is running a Windows 7 guest with PCI and VGA passthrough. Performance of the Windows guest is top notch. I...

This is certainly a VERY hot topic. I just contributed some $$ to the guy who accidentally burned up his GTX 680 while modding. I am very tempted to try one of those modified cards, though I don't have any need now. On a little different topic, I just published the Passmark results of a...

I believe I found something that might help: http://www.eevblog.com/forum/projects/hacking-nvidia-cards-into-their-professional-counterparts/msg207550/#msg207550. The entire thread is about hacking Nvidia cards to their professional counterparts, thus enabling some consumer cards to behave...

Subscribed. I would be interested in how this develops. Now my input: I'm running a Windows VM on a Linux Mint (Ubuntu) host with Xen hypervisor and VGA passthrough. The VGA passthrough is awesome and works really well (just like bare metal). My reason for choosing Xen over other solutions...

I haven't used FreeBSD for a long time, and the Xen related info I posted is from Internet searches. Looking at the FreeNAS website they do offer a x86 version, but it is unclear to me whether or not it comes with PVM in the kernel (or perhaps amd64 does too?). I found this thread that could...

As far as I know, FreeBSD is supported by Xen. See here: http://en.wikipedia.org/wiki/Comparison_of_platform_virtual_machines. Here is a somewhat old how-to on creating a FreeBSD guest under Xen: http://forums.freebsd.org/showthread.php?t=10268 I just noticed that the Xen compatibility list on...

I'm talking about the free, open source Xen hypervisor, not the commercial Citric Xenserver (I haven't used that). The main advantages I can see are: 1. VGA passthrough, and probably PCI passthrough - a.f.a.i.k. Xen was the first to offer that feature and still seems to be years ahead. Of...

Regarding the hypervisor, have you considered Xen? There are a few things where I believe Xen is ahead of the rest, incl. the commercial ESXi. Here is a shortlist on how I use Xen: 1. Linux Mint (Ubuntu) host OS (dom0) using multiple LVM drives (LVM = logical volume manager) 2. Windows 7 Pro...

Yes, .357 or later solves the problems! The latest drivers are .372 now. I downloaded and installed them today and they work too.

Thanks! Now I know what that is good for ;). Never thought of disabling cores - I paid too much money for them to let them rest idle.

Hm, how do you get "native, 3 cores" results? Is 3dmark able to use individual cores, so that you can tell it how many cores to use? The 3dmark doesn't show a big performance difference between native and virtualized, only ~2.6% in favor of native. That is totally negligible. As for 3dmark...

@Rody, @mathew7: If you refer to the Intel 3930K - it DOES support VT-d with the C2 stepping release. See the "description" at http://ark.intel.com/products/63697/Intel-Core-i7-3930K-Processor-12M-Cache-up-to-3_80-GHz. The spec code is SR0KY. In simple words: If you bought your 3930K within the...

It might be worth checking if your Nvidia card is supported. Some cards are.

If I look at their user forums it looks like the users face very much the same problems. I yet have to find a CEO who tells the IT guy: "That's too cheap. Get an expensive one." With limited budgets it's usually the IT guy who has to justify "wasting" the company's money. With regard to Asus...

Marvell SATA: If I understood the kernel dev correctly, the bug hasn't been solved by 3.6 and is difficult to fix. I didn't read his mail as a commitment to fix it after 3.6. It affects VT-d enabled systems, not if you run your PC the regular way (VT-d is disabled by default in most systems)...

Sorry, somehow I assumed you are going to install Windows as guest, which you didn't mention. What I wrote above goes for Linux guests as well, except the GPLPV drivers - just get a Xen-ified version of your favorite Linux distro, i.e. one that has the PV drivers, and install it as a guest.

What kind of connection do you have to your NAS? Ethernet, USB, eSATA, etc.? If Ethernet, which storage protocols does the NAS support? SMB (Samba), NFS? If it's via Ethernet, there could be a bottleneck with the Xen bridge. For example, I am running 10Gb between my Windows 7 VM and the...

Thanks for the detailed scores. Good that you mention your earlier thread at tomshardware - I remember it well and it helped me decide to jump into Xen with VGA passthrough. If I find some time I will try to run these tests as well, though my Nvidia Quadro 2000 won't be doing so well in this...

1. My WEI is based on a Sandisk Extreme 120GB SSD. But the trick was to install the GPLPV drivers from here: http://wiki.univention.de/index.php?title=Installing-signed-GPLPV-drivers*. * IMPORTANT UPDATE: Univention does not provide the latest drivers. To fix the Youtube video streaming issue...

+1 Sorry for answering to an old thread, but this is as relevant today. A workstation motherboard review should include virtualization AND Linux support. Testing VT-d is essential. So is a Linux test of the different hardware components. This board would probably fail with the Marvell SATA...

The right hardware is the most critical part of getting it up and running. There are a few how-tos available and it depends, which flavor of Linux you prefer. Here some links: For a Fedora (Red Hat) based how-to, look here...

Thanks, I heard about it and it's a valid point. Will both Windows 8 AND the Linux VM run like on bare-metal? What kind of a performance hit will the VM take? Could I play first person shooter games in a VM? There are a number of reasons I prefer to run Windows in a VM, and Linux as my...

I tried it. It works beautifully up and until one of two things: 1. Youtube video in Windows - somehow it stops all the time and loads endlessly. It might be a problem with my network setup, so I'm not sure this is the result of synergy. BUT, it also freezes the mouse :(. 2. Anytime I (or...

I tried pulseaudio but it turned out that the last driver developed for Windows was back in 2001 or so. I followed some guides but couldn't get it work. In the end I went to a computer shop and bought a $4 USB sound dongle (+$4 for a cable). The USB audio stick is in a USB port I passed...

Ran into this old thread, but since no-one answered this question, I thought a reply might be helpful anyway. The Nvidia Quadro 2000 can be successfully passed through under Xen. Other Nvidia cards that have been tested are Quadro FX 3800, 4800 and 5800. I believe all Nvidia cards that are...

I almost thought I'm in the wrong forum. So many VMware users and no Xen users? Anyway, here is my take: Asus Sabertooth X79 motherboard with 3930K (C2 stepping) and BIOS rel. 1203 32GB Kingston RAM AMD Radeon HD 6450 graphics card for Linux Nvidia Quadro 2000 graphics card for Windows...
