  1. So, I had a number of problems with other cards: I tried one other 4 port usb with dedicated channels so could forward to each VM which I just couldn't get unraid to recognise/work with 1. Startech PEXUSB3S44V 4 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter with 4 Dedicated 5Gbps Channels, UASP, SATA / LP4 Power Also had problems with a number of other standard usb hubs which didn't have dedicated channels with only some ports working for specific actions e.g. booting unraid but this seem to be due to a limitations of the total Number of usb port addresses that unraid or the bios was accepting to be allocated which the dedicated channels solved. So I suppose your mileage could vary but though it didn't work for me, try the startech one
  2. Code for passing through the first port for me is (obviously your port numbers may vary): </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x09' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </hostdev>
  3. Also put it in USB 3.0 but I'm pretty sure it was fine on 2.0
  4. First installed it on unraid 6.2 or 6.3, currently on 6.4
  5. Hi there, Been using this card for almost a year now with UNRAID i.e. before the mentioned article. I have an ASUS X99-WS/IPMI Motherboard. I pass each of the usb ports/controllers to a VM and they work great. The key was with the bios settings for me. Switch ACS to ON I believe, if I remember correctly (might have been a couple of other settings). Futhermore, last time I tried to install the official drivers for the card inside a VM having passed through the one controller, whilst it helped performance even more - it caused the VM to crash the entire of UNRAID host so best to not install those. Lastly to pass through I followed the following guide via the IOMMU method. Hope this helps!

    Cloning a VM

    Also, figured out that you can only reflink to the exact same folder. So in the case of @Nem, if he had done the above, to not get the error he got, he would need to have done: cp --reflink /mnt/cache/VM/UbuntuBase/vdisk1.img /mnt/cache/VM/UbuntuBase/disk1.img You can then copy the image to another folder however you cannot reflink from e.g. UbuntuBase to UbuntuNew, it has to the same folder it appears.

    Cloning a VM

    Figured out the soloution. Two things seem to create the problem you mentioned about invalid argument and 0KB. 1. If COW (Copy on Write) settings are disabled then this happens - this setting is in the share settings and you have to set it to "Auto" instead of "disabled" when creating the share 2. If you create your VM disk folders through the network/SAMBA I.e. You access it from my network places and you create subdirectories via that in Windows then try to cf reflink to there. The way around this is is, go to your VM, create a vdisk through the settings panel in a new folder of your choice, going via usershares to navigate to the folder of your choice.. Then delete the vdisk1.img and use the standard instructions posted above and being aware of not doing from 1 disk to another or going via user shares. This seems to do the trick, I'm new to UNRAID but that worked for me. Hope it helps!
