My hero. Worked straight away for me too. Thanks for posting this!

Has anyone had any success using one of these? I'm using a high spec AMD system but just get a black screen when using it. I'm connected to my VM with VNC, with an HDMI dead header in the graphics card. I've tried selecting it from the device list in the VM settings (doesn't even start the VM) and also using vfio.cfg to isolate the USB devices. The OS sees it but I just get the black screen. I can provide more info if needed but really looking for anyone with a working HDMI capture in a Windows VM. I can send it back and get a different device if needed. Cheers.

I'm on beta1. Installed beta22, here's what broke: Samba fell off domain VMs all disappeared (I have custom settings for VM storage and libvirt location) Cache drives no longer assigned to cache System hung and needed a forced reset I rolled back and then had to fix VM locations etc.

Hi there I've searched and searched and found so many different pieces of information over the past few years and not found anything that truly answers my query. I have a virtual bridge, virbr0 which I use with my VMs. How can I access/assign a Docker container to this virbr0? There is nothing in the GUI that allows me to select it. Thanks!

In case anyone stumbles across this thread here's what I ended up doing. I have two NICs, one 1Gbe and one 10Gbe The 10Gbe is linked to the br0 bridge and routing table ensures this is the primary NIC/Bridge 1Gbe NIC linked to br1 bridge which is assigned to the Windows VM To ensure fast transfer between UnRAID and the VM I also added virbr0 to the Win VM. I now can transfer across the network from SMB shares on my Synology without the CPU issue but keep the fast transfer with UnRAID shares (otherwise I'd be going back out to the network and only getting 1Gbps speeds).

Are you passing this through using the UnRAID GUI interface? I.e. from the drop down list on the VM config page?

Further update: upgraded to “next” branch of UnRAID. Problem is actually worse - now two cores on max with stuttering still

Some further testing. Swap the primary network port for UnRAID to the Intel Gbe interface. The problem in the VM goes away. Pass through the ACQ107 adapter through to the VM - works fine - no stuttering. Pass through the Intel adapter through to the VM - works fine - no stuttering. So, this looks like an ACQ107 / Kernel driver type thing. Some kind of issue at that level. Any ideas anyone? Or can anyone recommend a 10Gbe network card known to work?

Hi all I’ve been working on this for two days now and I’m running out of ideas. In summary, when I use my Windows 10 VM to copy files from an SMB share on a separate NAS, I’m seeing stuttering on the VM (mouse sticking/jumping etc) and on the UnRAID main screen, I see a single CPU core running at 100%. I have a 10Gbe network connection on the UnRAID host to a switch which by all accounts is working well - the transfer rates are as expected. But the VM stuttering is problematic. The network adapter is: Aquantia Corp. AQC107 NBase-T/IEEE 802.3bz Ethernet Controller Here’s what I’ve tried so far: New VM from scratch - same result Using TeraCopy - actually less stuttering but half the transfer speed Trying vmxnet3 driver instead - same result - stuttering Tips and Tweaks - Disable flow control (no change) Tips and Tweaks - Disable NIC offload (no change) New VM without Passthrough - a little better, but still seeing the CPU spike Adding more cores - but does nothing as this seems to be a single thread process I’m at a loss. If it helps here’s the VM XML but I’ve tried all kinds of combos here to no avail: <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm'> <name>Windows 10 Test Passthrough</name>
