And no, I don't want to risk ~$800 in GPUs to bios flashing and resistor hacking to try and "turn them into" Quadros. But I have 2 separate GPUs I want to use for this, and I want to run one single OS per GPU. Multi-OS as far as I can tell means one card, more than one OS (ie: multiple GPUs on one card). Everything points to the professional/Quadro cards for "multi-OS" capability. This is something I've been wanting to get set up, myself, but I can't find any solid information on whether vga passthrough will work with Nvidia's consumer cards. Originally posted by eric:So I built a multiheaded SteamBox, this one is a little different on the inside: I can certainly post videos or screenshots in the appropriate tabs in the hw forum. The Datastore which contains the VM’s can be an iscsi target, so another ESXi box can run the VM’s stored there. The box is actually portable (luggable?) with a handle on top, for LAN parties. From the App you can power on VM’s, take or return to snapshots, and manage which display is assigned to a VM. This is not exactly End-User friendly, so I wrote an Android App to manage the VM’s residing on this box. VMware ESXi normally requires the Vsphere Client for management to be run on a separate pc or VM. One VM runs in the background with a wifi card passed through, acting as an integrated WiFi access point. These can run out of the HD 4650, or any of the HD 6450’sĪll simultaneously with the SteamOS’s, in any combination. I also have other VM’s of other OS’s defined.
I can also define many more SteamOS VM’s, and run any 4 of my choosing. They can all be returned to “New Install” state at any time. The VM’s are protected by snapshots, so no need for a recovery partition. I only gave the VM’s 2 cores from the i7 initially. The performance is equivalent to a SteamBox on a dual core board with the same graphics card. The RAM assigned is owned by the VM, but CPU cores can be over-provisioned. How much RAM or CPU cores are assigned to each VM is defined in its config. PCI Passthrough is where the physical hardware is passed through to the VM, with its full capabilities. These run concurrently, side by side, each using one of the HD 6450’s.and a USB using PCI Passthrough. I have multiple VM’s defined, 4 of which are SteamOS. This runs VMware ESXi 5 on the bare metal, using the 2gb SSD and the Nvidia PCI card as the console. So I built a multiheaded SteamBox, this one is a little different on the inside:
