  1. Hi there,

     

    Unfortunately these types of issues can happen when you use AMD-based devices (CPU/GPU) for use with VFIO.  There is just a lack of consistency with the experience across kernel and package updates.  These issues don't seem to plague NVIDIA users.  There is a limit to how much we can do to support AMD when they aren't even supporting this themselves.  I wouldn't call this as much a "bug" with Unraid as it is with the kernel itself and from our perspective, having problems with AMD-based GPUs and GPU pass through is a known issue and limitation of AMD.  Hopefully AMD will do a better job supporting VFIO in the future.

  2. Hi @Mirai Misaka, if you try to install a new Windows VM from scratch, do you still get the Code 43 error?  We need to isolate whether this is an issue within the guest OS or something to do with the host configuration.  @bigbangus had a similar issue after updating to 6.10, but found the problem was that the NVIDIA driver needed updating there.

     

    Another possible issue is whether or not this system features an integrated graphics device and whether that device is enabled or not.  Generally speaking when you want to pass through a GPU, you need one GPU per guest and one for the host.  In your setup, you seem to only have the two GPUs.

     

    I know that some users have found workarounds to making the primary GPU pass through, but NVIDIA does not officially support that configuration as an FYI:  https://nvidia.custhelp.com/app/answers/detail/a_id/5173/~/geforce-gpu-passthrough-for-windows-virtual-machine-(beta)

    Do you need to have more than one GPU installed or can you leverage the same GPU being used by the host OS for virtualization?

     

    One GPU is required for the Linux host OS and one GPU is required for the Windows virtual machine.

     

     

  3. And are both of your VMs experiencing this same issue with each GPU?  If you're having bad performance in Windows outside of games as well, this is unlikely a bug with GPU pass through, but rather, something amiss with CPU virtualization/pinning.  Can you confirm both of those Windows VMs you have experience the same issue and that the issue persists even with only one VM running at a time?

  4. Hi there,

     

    For those having this issue, please report back with a copy of your system diagnostics, and any relevant A/B testing you've done comparing 6.9-series VM performance to 6.10.  For game-specific testing, please list the games you've tried.  We're actively trying to recreate these issues in the lab, but so far, no dice.

  5. Hi there,

     

    One issue could be that if you're loading the GPU driver to use the GPU with a Docker container, then you can't also use that GPU with a virtual machine.  GPUs need to have their driver stubbed in order to be used in a VM.  When you use the NVIDIA plugin, it installs the driver for the card which prevents you from using it in a VM.  This is not a bug.

    Hello there,

     

    Like mentioned in the recent unraid podcast, I am wondering if the SMB Multichannel is enabled in this release candidate.

    If so, second question, I have two servers both with bonded network connections (802.3ad), is it recommended to keep bonded to use multichannel, or remove?

     

    Cheers,

     

    -jj-

     

    Ready for these uber-complicated instructions?  Just kidding!  It's easy!

     

    First you'll need to stop the array, then navigate to the Settings > SMB Settings page.  From here, modify the SMB Extras section and add the following:

    server multi channel support = yes
    aio read size = 1
    aio write size = 1

    Save the changes and then start the array.

     

    WARNING:  THIS IS STILL CONSIDERED EXPERIMENTAL!  We haven't done sufficient testing with this yet, so feel free to use it, but do so at your own risk.

     

    Something else worth mentioning is that according to the Samba project, as recently as a few days ago Samba 4.15-rc2 was released and there was this interesting note in there about multi-channel:  https://wiki.samba.org/index.php/Samba_4.15_Features_added/changed#.22server_multi_channel_support.22_no_longer_experimental

  7. Hey everyone, just a quick update on this issue. The main problem we've faced is the inability to recreate this issue in our labs. We are still actively working on it, but if anyone here knows the full solution, we are open to providing a bounty for it. Just PM me and so long as the fix isn't a hack or workaround, we will gladly compensate you for your time and work. 

  8. Hi there,

     

    As an FYI, I wouldn't have reported this as a "bug" just yet, as this could be something amiss with your system.  If this was a bug related to Samba, I'm fairly certain we'd have a plethora of users reporting the same thing.

     

    The first thing I'd like you to try is rebooting in safe mode.  See if you can reproduce the issue in that mode.  If so, please reattach your diagnostics after you've reproduced it in safe mode so we can review again.  Thanks.
