Is Dwolla good? That and BTC are the only good ways for me to receive money right now, as my PayPal account is frozen because I'm not 18. A check would work too.

How did they find out? I set up my PP account several years ago when I was also under 18, had it connected to my bank account and card (visa electron) and never had any problems buying or selling worldwide, before and after turning 18.

I decided to communicate with someone via email, and they googled my address and reported me.
What's funny is it was my first purchase of some GPUs to get into mining about a year ago.

I was really lucky a I had just traded a good sum of cash for pp with a friend less than a month before that, and pp only allowed me to refund money, so I only have 20someting in there now.

I ran into some problems with the controller last night when trying to specify channels, but I've almost sorted that out, so you can still expect it to ship Monday.

I don't know when I'll be able to test it beyond just booting up (it does boot fine, BTW), might have to wait til Saturday.

Yes, each one is basically a complete computer on a card - processor, RAM, integrated video, SATA, Ethernet, Serial, and so forth. The backplane is strictly for expansion and power. Only one per system, with this backplane.

Does this mean you are building two of these beasts now? Why do you have the "brain" for two?
The first one I got when I first started the project, but it was a cheap $200 card with ancient processors that didn't support any form of virtualization. With proper drivers that supported more than 8 devices, I would be able to use it, but with the current crippled drivers I had to shell out for a board that was capable of virtualization. The new card is a C206 chipset with an E3-1225 processor.

As much as I like this project ( I actually was hoping / dreaming somebody trying this ), I think the $$$ is too much compared to normal cheap mobo setup.

Otherwise, great job rjk !

I have provided some incorrect info earlier on debian specifics on virtualization with KVM and Proxmox VE, I'm here to correct it. Also it looks like there is a newer version that I haven't used, so YMMV with all this. If you do go the PVE route and a KVM hypervisor, here's the docs I dug up:

Basically, you'll have a debian install and need the device ID's for all the video cards:

Code:
lspci -v |grep VGA
04:00.0 VGA compatible controller: ATI Technologies Inc Device 6719
05:00.0 VGA compatible controller: ATI Technologies Inc Device 6719
0a:00.0 VGA compatible controller: ATI Technologies Inc Device 6719

I posted incorrect paths to VM config files, the actual path is:

Code:
/etc/qemu-server/VMID.conf

Full documentation on these options:
http://pve.proxmox.com/wiki/Manual:_vm.conf

At the bottom of this page, it describes the format for PCI passthrough of Device IDs:
http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM

IMO, the steps above "VT-d device hotplug" I believe to be unnecessary with PVE.
To reiterate, my functional steps to get working PCI passthrough working in the past with this setup has been:

1. enable VT-d in the BIOS. This will let us create and install KVM virtual machines once PVE is installed.
2. install PVE. It's bare-metal and uses all disk space.
3. Log into web interface, create VM however. Stop it.
4. edit my vm .conf file and add the device ID. For you, this might be something like:

Code:
device_add pci-assign,host=04:00.0,id=GPU0
device_add pci-assign,host=05:00.0,id=GPU1
device_add pci-assign,host=0a:00.0,id=GPU2

5. start your VM with new VGA devices detected.

When I say VMID, I mean the standard naming convention in PVE of 101 for the first VM, 102 for the second, and so on with the defaults. One of those links says you can do this hot-plug from a kvm guest console, which is available from web interface or cli. I've never tried that myself.

More links:
http://www.linux-kvm.org/page/VGA_device_assignment
http://www.linux-kvm.com/content/pci-passthroug-digital-devices-cine-s2
http://pve.proxmox.com/wiki/Tape_Drives

http://pve.proxmox.com/wiki/Manual:_qm
The qm (man qm)command is your friend for kvm VM management from cli on this distro.
Commands like "qm start 101" are instant win. See this:

Code:
-hostpci[n] HOSTPCIDEVICE
 
             Map host pci devices. HOSTPCIDEVICE syntax is:
             
             'bus:dev.func' (hexadecimal numbers)
             
             You can us the 'lspci' command to list existing pci devices.
             
             Note: This option allows direct access to host hardware. So it
             is no longer possible to migrate such machines - use with
             special care.
             
             Experimental: user reported problems with this option.

So another less supported option, which I have most likely used is to simply issue a command(s) like:

Code:
qm -hostpci0 05:00.0
qm -hostpci1 04:00.0
qm -hostpci2 0a:00.0

To add my PCI devices.


http://pve.proxmox.com/wiki/Pci_passthrough
This one details "enabling" PCI Passthrough in PVE 2.0 - which I haven't used yet. This step hasn't been required in the past up to PVE 1.9 to my knowledge, but may be required now. Idk here with this.... this seems new to me, never have performed this step to my knowledge.

Enjoy the info dump homie Wink

info
OK, I installed Proxmox VE, and have a few notes. I tried to get you on IRC, but I guess you were away.

The config files appear to be in /etc/pve/qemu-server not /etc/qemu-server Grin
I can see the video cards in lspci (testing with 4 cards to start):
Code:
root@HASH9000:/etc/pve/qemu-server# lspci -v | grep "Cypress XT"
06:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Cypress XT [Radeon HD 5870] (prog-if 00 [VGA controller])
08:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Cypress XT [Radeon HD 5870] (prog-if 00 [VGA controller])
0a:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Cypress XT [Radeon HD 5870] (prog-if 00 [VGA controller])
15:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Cypress XT [Radeon HD 5870] (prog-if 00 [VGA controller])
When I run these commands:
Code:
root@HASH9000:/etc/pve/qemu-server# qm monitor 100
root@HASH9000:/etc/pve/qemu-server# device_add pci-assign,host=06:00.0,id=GPU0
it is epic fail; it causes a kernel panic with the following output:
Code:
root@HASH9000:/etc/pve/qemu-server#

 kernel:Kernel panic - not syncing: Fatal exception
Sad
Pasting the following lines in 100.conf did nothing at all:
Code:
device_add pci-assign,host=06:00.0,id=GPU0
device_add pci-assign,host=08:00.0,id=GPU1
device_add pci-assign,host=0a:00.0,id=GPU2
device_add pci-assign,host=15:00.0,id=GPU3
And finally, these:
Code:
qm -hostpci0 05:00.0
qm -hostpci1 04:00.0
qm -hostpci2 0a:00.0
appear to be invalid commands.

So do you have any other ideas? The host is Proxmox VE 2.1, and the guest is Debian netinstall 64-bit with the GUI enabled.

sorry dog, I'm in the middle of a lake, plus i'm not sober. one of those links mentioned "enabling" pci passthrough. Like Isaid I haven't tried 2.0+ yet, the instructions looked different. If you have time you could try 1.9 install or try the pve forums. Maybe wait til I sober up as well.
QFT lol. I did run the enable step, it was basically just editing grub.conf to add a flag to enable VT-d. No errors there. I'll check a few other places and maybe give 1.9 a shot.

qm hostpci[n] <device id> your device id's are different than what i posted. also notice that.
OK I think I'm getting somewhere - I put this in the config file:
Code:
hostpci0: 06:00.0
hostpci1: 08:00.0
hostpci2: 0a:00.0
hostpci3: 15:00.0
and the VM started, but now I can't access its VNC terminal, it is just blank. I forgot to get its IP so I can't connect with SSH. I'll need to shut it down and remove the devices and boot it up and get the SSH config.

Update: removing all but one of the hostpci lines from the config file results in the guest booting, but not all the way. It seems to have trouble starting X; the VNC connection just flashes on and off endlessly, but the guest does respond to ACPI button commands, if nothing else. In this state, SSH doesn't seem to be enabled either.

I'll have to tinker with it later; I have other things to do right now. But thanks for the tips so far.

ah I see, it is the Advantech PCE-5126WG2-00A1E  right? sorry for not reading everything (have done it now:) )
That's the one. And since I never gave a review of it earlier, I'll take the opportunity now to lay out a few points.

First, it is definitely less solid than the old Trenton board that I had before, in terms of build quality, etc. The board material seems to be a bit thinner and more flexible, and it actually came to me somewhat warped in spite of the stiffening/strengthening bar that is soldered across its length on the bottom. Fortunately, it wasn't too far off (just a few millimeters), so I was able to gently bend it back enough so that it would slot into the backplane slots.

It also seems to have a slightly less than ideal labeling on the various connectors and headers; they are all mixed in with the usual board labels such as resistors and caps, making it occasionally difficult to determine which label goes with which header. I had to reference the manual to be sure I got each connection perfectly correct.

Other than that though, it is a stellar performer. I guess you have to weigh your options between Trenton's equivalent option - the cost difference could be a deciding factor for some people, and I can say I would purchase again, because it does what it is intended to do just fine. It is loaded with almost every feature that is available on the C206 chipset, and with others besides. I guess the I would recommend Trenton's option if absolute uncompromising build quality is needed, such as in high vibration environments (airplanes, etc.), where cost isn't an object.

The BIOS is reasonably clear and understandable, with a mostly standard layout. One thing that I didn't see was the 64-bit BIOS address table option, but that may require a custom BIOS. I'm going to keep trying to see about getting it working sometime soon.
