Hi all, Thought I'd share some experiences thus far on trying to passthrough a PCIe USB controller to a W11 VM. Context: Was trying to get USB audio devices (Razer Blackshark V3 Pro) to play properly without stuttering. tl;dr this is a known issue with some VMs, where USB-based audio stutters b/c of incompatibilities in the system. The general solution is to pass-through an entire USB controller. Problem: Z690 Mobo, 12600K, only has one USB controller for all ports and can't pass that through. Solution: FebSmart Renesas UDP720201-based PCIe controller card, which got my Blackshark to register completely (including Synapse) as well as my USB BT dongle. Also tried: Yeelink ASM3142**-based PCIe controller card. **Caveat: It's possible that the ASM3142-based card did not work b/c I have a ASM-based SATA controller on the motherboard as well. Failed: Highpoint RU1144D which would load the BT dongle and Blackshark but not completely. In particular, the Blackshark would show up in Windows but not in Synapse, so I couldn't adjust its EQ. The dongle also appeared but wouldn't pair to some devices. I had hoped this one would work b/c it has 4 separate USB controllers, meaning you could assign them to multiple VMs if you wished Other people have recommended FL1100-based cards, e.g. the updated Yeelink one or the Inateck

I'm also noticing this problem: Aug 14 01:12:16 Unimatrix001 flash_backup: adding task: /usr/local/emhttp/plugins/dynamix.my.servers/scripts/UpdateFlashBackup update Aug 14 02:12:16 Unimatrix001 flash_backup: adding task: /usr/local/emhttp/plugins/dynamix.my.servers/scripts/UpdateFlashBackup update Aug 14 07:12:17 Unimatrix001 flash_backup: adding task: /usr/local/emhttp/plugins/dynamix.my.servers/scripts/UpdateFlashBackup update Aug 14 09:42:18 Unimatrix001 flash_backup: adding task: /usr/local/emhttp/plugins/dynamix.my.servers/scripts/UpdateFlashBackup update Aug 14 12:12:21 Unimatrix001 flash_backup: adding task: /usr/local/emhttp/plugins/dynamix.my.servers/scripts/UpdateFlashBackup update Aug 14 12:42:21 Unimatrix001 flash_backup: adding task: /usr/local/emhttp/plugins/dynamix.my.servers/scripts/UpdateFlashBackup update I believe this is also responsible for spinning up the array even though there's nothing else going on. unimatrix001-diagnostics-20250814-1420.zip

I'd say it's a perennial issue. I'm still unclear which cards are confirmed to work w/ Unraid 7.1.4 to passthrough to a W11 VM...

Hi, Is it possible to cache the directory list (not the files) when accessed by Windows over SMB? I know there's the Dynamix plugin, but as far as I can tell, this only works when you're viewing the directory from inside Unraid's GUI and not any other way? Alternatively, what's an easy way to see directory/information without spinning drives besides the Unraid GUI?

This is a very interesting topic. I was about to run defrag on my drives to figure this out... For me, I'm seeing ~2% usage on an empty 24TB drive, which seems like a lot, since the 14TB drives these are replacing used 96GB or so. As I understand it then, w/ reflinks and crc enabled, this 2% usage of an empty drive is operating as intended?

Hi all, I'm trying to passthrough a USB audio device to my W11 VM. In particular, a Razer Barracuda X (wireless, via USB) or a Steelseries Arctis 5 (wired, via USB). No matter what I do, the audio will cut in and out randomly, eventually disconnecting altogether. It can be reset by disconnecting and reconnecting the audio via the USB plugin. I've tried passing it through via the XML template and via the USB plugin. I've also tried reducing some load (by *not assigning the HT core to the VM, even though its isolated). I saw this recommended in another forum, suggesting that the CPU is too busy, so by isolating the cores but not assigning the cores it'll work better. It hasn't worked for me. Any other ideas on how to do this?

I tried adjusting "interrupt moderation" on the W11 computer I'm transferring from to no real difference, per this thread Any other ideas?

I switched to W10 and now it's even worse, running at 1 Gbps, even though everything is using virtio drivers. Help please! Transferring within the VM, 980 -> SN8200 gives me 1.8 GBps so it's not the drive itself.

Hi all, I'm racking my brain trying to figure out why my W11 Pro VM is only transferring ~250MBps to my Unraid cache. As I understand it, the SX8200PNP drives have ~3000 MBps sustained transfer even after the cache is full, so this result is much slower than I'd expect. I'll list components below along w/ things I've tried: Components 11700K on Asus Strix Z590-E 2.5 Gbps Intel I-225V network port W11 VM 10 cores, 24GB DDR4 RAM Samsung 980 Pro 2 TB passed through via config (not IOMMU) AData SX8200PNP 2 TB pass through via config Unraid cache AData SX8200PNP 2 TB btrfs Array 13x WD 14TB (shucked aka red plus) Switch Netgear 2.5 GbE switch Tried Using Netgear 2.5 GbE switch Removing cache pool (used to be RAID0 2x2 TB Adata) Switching from e1000 to virtio-net to virtio Some questions: The virtio driver says 10G, which is ofc emulated, so it shouldn't be affected by the hardware 2.5 GbE, correct? Transfers from the VM to the Unraid cache aren't actually going through my network card, correct? Thanks for the help!

I did this but now transfers are limited to 1 Gbps. Is there a way to revert this to virtio-net afterwards (and still work)? When I changed to virtio, Windows complaints it doesn't have a network card ><"

Hi, I'm having trouble after passing through a NVMe drive (used to passthrough a SATA drive instead) to my W10 VM. Asus Z270-A Prime Nvidia 1030 Intel i7-6700K NVMe: Samsung Evo 970 Plus 500 GB Some debugging info: VT-D is on The NVMe drive has a bare-metal installed version of W10 Pro (same as the SATA drive prior) I followed SpadeInvaderOne's instructions to set the function 0x1 properly for the GPU.

Gotcha! I'll turn on turbo-write for large transfers. I recall reading that the virtio drivers emulates a 10G NIC but my motherboard only has a 1G NIC. Am I technically bottlenecking myself at 1G because of it? Specifically, if I change the NIC to a 10G card (and network switch), would I transfer to my cache drive at 10G instead?

Hi all, I've been setting up UnRAID for the first time and having a blast. Now that initial drive setup and files are transferred, I've setup my parity drive. However, transfers to the drives is very slow (~50 MBps) even between the Win10 VM and the server itself. For comparison, disk to disk transfer via Krusader is ~150 MBps, Preclear/parity was ~190 MBps. Transfer over the network, prior to the parity drive was 130 MBps (in line w/ gigabit ethernet). These are all numbers without a cache drive. So question is, 1) how do I get it past 50 MBps or is this a limitation of the parity process? 2) Is it worth it to get a faster NIC? It seems that when using the VM to send data to the share, I'm technically sending data to the router and back, thus capped at my ethernet speed. If I were to get a 2.5 or 10 GbE NIC+switch, would that mean that I'd transfer closer to the max speed of the drives? Relevant hardware: CPU: Intel 6700k RAM: 32 GB (16 allocated to W10 VM) Mobo: Asus Z270-A Prime NIC: integrated gigabit Array: 5x 12 TB WD Red (incl. 1 parity) Thanks!!

I tried this but it didn't work. Just making sure I did the correct thing: completely new install. I had stubbed the NVMe, then unstubbed it, and referred to the NVMe by it's id (the whole drive). Did I do that correctly? Should I refer to one of the partitions in particular?
