Did you try looking in device manager for unidentified devices/scanning for new devices? I had to manually direct it to the virtio SCSI driver before the disc drive showed up.

I'm successfully passing through a BluRay drive to Win7/10 by adding the following to my XML <hostdev mode='subsystem' type='scsi' managed='no'> <source> <adapter name='scsi_host7'/> <address bus='0' target='0' unit='0'/> </source> <readonly/> <address type='drive' controller='0' bus='0' target='0' unit='2'/> </hostdev> To pass though the following drive [0:0:0:0] disk Lexar JD FireFly 1100 /dev/sda ...

After reading this thread I was a bit worried about trying a USB soundcard since my motherboard doesn't have onboard sound to pass though to a VM. Despite this, I went ahead and ordered an Asus Xonar U3 and figured if I had an issue with static I'd get a USB PCIe card to pass though. I plugged in the U3 into a front panel USB port, passed it though, Windows 10 automatically detected it and installed a driver but the volume was abnormally loud and turned all the way down it was barely comfortable to listen to. So I downloaded Win8.1 drivers from Asus (they're lacking in Win10 support) and installed them. Now the volume levels are normal and I don't have any detectable static even with some good IEMs.

I recently built a new system for unRAID so I could virtualize a couple systems and ran into an issue with using pass-through on certain pcie slots. I think I figured out a solution and thought someone else might find it useful. CPU: E5-1650v3 Mobo: Supermicro X10SRH-CLN4F GPU: EVGA GT 730 HBA: LSI 9211-8i (M1015) unRAID migration from one system to another was simple enough after I figured out I needed to disable UEFI (leaving only legacy) boot on my UnRAID flash drive in the BIOS. The system ran perfect with the HBA in the lowest slot (slot 2, pcie 2.0x4in8). Then I added my GPU, in the slot the HBA was in, and moved the HBA to the next upper slot (slot 4, pcie 3.0x8). System boots fine and everything is listed under system devices correctly. 00:00.0 Host bridge: Intel Corporation Xeon E5 v3/Core i7 DMI2 (rev 02) 00:01.0 PCI bridge: Intel Corporation Xeon E5 v3/Core i7 PCI Express Root Port 1 (rev 02) 00:02.0 PCI bridge: Intel Corporation Xeon E5 v3/Core i7 PCI Express Root Port 2 (rev 02) 00:02.2 PCI bridge: Intel Corporation Xeon E5 v3/Core i7 PCI Express Root Port 2 (rev 02) 00:03.0 PCI bridge: Intel Corporation Xeon E5 v3/Core i7 PCI Express Root Port 3 (rev 02) 00:03.2 PCI bridge: Intel Corporation Xeon E5 v3/Core i7 PCI Express Root Port 3 (rev 02) 00:03.3 PCI bridge: Intel Corporation Xeon E5 v3/Core i7 PCI Express Root Port 3 (rev 02) 00:04.0 System peripheral: Intel Corporation Xeon E5 v3/Core i7 DMA Channel 0 (rev 02) 00:04.1 System peripheral: Intel Corporation Xeon E5 v3/Core i7 DMA Channel 1 (rev 02) 00:04.2 System peripheral: Intel Corporation Xeon E5 v3/Core i7 DMA Channel 2 (rev 02) 00:04.3 System peripheral: Intel Corporation Xeon E5 v3/Core i7 DMA Channel 3 (rev 02) 00:04.4 System peripheral: Intel Corporation Xeon E5 v3/Core i7 DMA Channel 4 (rev 02) 00:04.5 System peripheral: Intel Corporation Xeon E5 v3/Core i7 DMA Channel 5 (rev 02) 00:04.6 System peripheral: Intel Corporation Xeon E5 v3/Core i7 DMA Channel 6 (rev 02) 00:04.7 System peripheral: Intel Corporation Xeon E5 v3/Core i7 DMA Channel 7 (rev 02) 00:05.0 System peripheral: Intel Corporation Xeon E5 v3/Core i7 Address Map, VTd_Misc, System Management (rev 02) 00:05.1 System peripheral: Intel Corporation Xeon E5 v3/Core i7 Hot Plug (rev 02) 00:05.2 System peripheral: Intel Corporation Xeon E5 v3/Core i7 RAS, Control Status and Global Errors (rev 02) 00:05.4 PIC: Intel Corporation Xeon E5 v3/Core i7 I/O APIC (rev 02) 00:11.0 Unassigned class [ff00]: Intel Corporation C610/X99 series chipset SPSR (rev 05) 00:11.4 SATA controller: Intel Corporation C610/X99 series chipset sSATA Controller [AHCI mode] (rev 05) 00:14.0 USB controller: Intel Corporation C610/X99 series chipset USB xHCI Host Controller (rev 05) 00:16.0 Communication controller: Intel Corporation C610/X99 series chipset MEI Controller #1 (rev 05) 00:16.1 Communication controller: Intel Corporation C610/X99 series chipset MEI Controller #2 (rev 05) 00:1a.0 USB controller: Intel Corporation C610/X99 series chipset USB Enhanced Host Controller #2 (rev 05) 00:1c.0 PCI bridge: Intel Corporation C610/X99 series chipset PCI Express Root Port #1 (rev d5) 00:1c.6 PCI bridge: Intel Corporation C610/X99 series chipset PCI Express Root Port #7 (rev d5) 00:1d.0 USB controller: Intel Corporation C610/X99 series chipset USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation C610/X99 series chipset LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation C610/X99 series chipset 6-Port SATA Controller [AHCI mode] (rev 05) 00:1f.3 SMBus: Intel Corporation C610/X99 series chipset SMBus Controller (rev 05) 00:1f.6 Signal processing controller: Intel Corporation C610/X99 series chipset Thermal Subsystem (rev 05) 01:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS3008 PCI-Express Fusion-MPT SAS-3 (rev 02) 04:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03) 06:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 06:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 06:00.2 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 06:00.3 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 08:00.0 VGA compatible controller: NVIDIA Corporation GK208 [GeForce GT 730] (rev a1) 08:00.1 Audio device: NVIDIA Corporation GK208 HDMI/DP Audio Controller (rev a1) 09:00.0 PCI bridge: ASPEED Technology, Inc.

Stop Array. Reboot. Start Array. Checked with cat to see if the change is persistent, it was. Now pass-through works in slot 2 and everything else still works as it should. I'm not sure what the root cause of this issue is (if it's a compile time decision, 2^5 seemed like enough?). If there's a reason I shouldn't do this please let me know. I don't see any issues since the slots are in their own IOMMU groups. There's no reason currently that required me to passthough a device in the lowest slot, I just wanted to so the GPU didn't block another expansion slot. P.S. I had a major scare/issue when trying different pcie slots. [*]set passthough for GPU in slot 2 to VM [*]HBA in slot 4 [*]Attempt to start VM, ACS related error message results [*]Shutdown [*]GPU in slot 2, HBA in slot 4 [*]Power on, start array [*]Start VM...ALL drives on HBA disappear from array [*]Stop everythin, reboot, drive reappear Result: VM address settings for passthough addresses persist after hardware changes is you don't update them. So when I started the VM it tryed to pass through a GPU in the slot my HBA was in which dropped all the drives connected to it from my array.

Mobo, CPU, and RAM arrived today but the cooler Amazon sent me had been mounted(used thermal paste) and mishandled(bent fins) so I'm waiting for a replacement until Monday. Going to see if I have a different cooler to make work for the weekend to test everything. Also picked up a GT 730 refurb to try out in the HTPC VM. I think it should be enough for 1080p@24/30/60fps and as a bonus it's an x8 physical card.

Promo Code: EMCKAAW44

Oops, copy/paste error. I did decide to spring for the E5-1650v3. According to that spec, the x16 slot will always run at x8 [PCIe 3.0]. (Additionally, two x8 slots [ 1 PCIe 3.0, 1 PCIe2.0] will always run at x4, 2 x8 slot [PCIe 3.0] at x8, and the x4 slot [PCIe 2.0] always runs at x2 Yes, no PCIe switches on this board. All slots are fixed, diagram in pg 23 in the manual shows this. I plan on using the x16(x8 elec.) slot for my desktop VM GPU and when I need another I will have to get creative and use a riser/adapter or modify a slot to accept another x16 card. I'm not concerned with the x8 bandwidth affecting the performance with what I'll be using it for. Without modifying anything I think you might need to look at boards based on the X99 chipset if you need more x16 slots.

Thanks for everyones input. I would like to have gone with a dual cpu motherboard and 2x E5-26xx but I can't justify the expense for what I'll be using the system for (maybe the next build... ). Ordered: Motherboard: Supermicro X10SRH-CLN4F (LSI3008, Quad GigE, 10 Sata, ) CPU: Xeon E5-1620v3 (considering E5-1650v3 but +50% performance for 2x cost) Xeon E5-1650v3 RAM: Crucial 16GB DDR4 ECC Cooler: Noctua NH-U9DXi4 Noctua NH-U12DXi4 (Still have room for 3x3.5" and a 5in3 so I won't need a new case soon and I figured more cooling can't hurt)

I think a single E5-16xx should be more that enough power for me too. It also appears the E5-1650v3 and E5-1660v3 are still unlocked so a minor OC is still possible to get a little more performance if you don't mind the stability risk.

I was looking at a couple Supermicro boards. After looking through them again I do see they vary individually with some having 2-3 PCIe on the first CPU. I do agree that it would be great for expansion but I think I'm going to go with a single CPU because 1) motherboard is cheaper, 2) CPUs are cheaper, 3) I'd have to get a new case now New build is already pushing the budget a little since I originally started looking at just an E3v3.

Leaning more towards the E5-1650v3 now. I did consider a dual processor board but they have to divide bandwidth between two processors i.e. CPU0 is connected to onboard/1 PCIe and CPU1 is connected to remaining PCIe slots. This meant I would have to start with two processors in order to have the PCIe slots I need.

Since my current desktop is showing its age along with my unRAID server I think it's time to upgrade. I'm currently leaning toward a Xeon E5v3 based system over E3v3 because of the increased I/O (40 vs 16 pcie lanes) and RAM since I plan on virtualizing my desktop immediately and probably 1-2 HTPCs soon after. I considered waiting for E3v5 Xeons which are supposed to have a few more PCIe lanes and RAM but I need an upgrade sooner rather than later. Here's what I'm considering: From existing system: PSU: Seasonic X-850 Case: Fractal Define XL OS: unRAID 6 Pro + Lexar 8GB Flash HBA: LSI9211-8i IT (M1015) Drives: 256GB SSD, 2x2TB, 4x3TB, 2x4TB GPU: GT 730 Stage 1 (Now): Motherboard: Supermicro X10SRH-CLN4F (LSI3008, Quad GigE, 10 Sata, ) CPU: Xeon E5-1620v3 (considering E5-1650v3 but +50% performance for 2x cost) RAM: Crucial 16GB DDR4 ECC Cooler: Noctua NH-U9DXi4 (92mm vs 120mm for future 4U case upgrade) Stage 2 (0-3 months): RAM: Crucial 16GB DDR4 ECC GPU: GTX 970 (Not necessarily this exact variant, maybe a newer gen by then) Stage ?: RAM: Crucial 16GB DDR4 ECC x2 Case: Norco 4224 GPU (for HTPC) I will be running 5-10 Dockers and multiple VMs to start (2x Windows 7(main desktop, HTPC), CentOS 6 (dev), OSX Mavericks (test)) and adding more as needed. No parts are for sure other than what I already have. Let me know if you recommend any changes.

Not sure on your budget but CaseLabs has some nice stuff.
