So I did a little experiment and used a bare SSD drive for my Windows gaming VM everything worked great and there was some performance improvement in the VM. But I made the mistake of booting into Windows and now my Nvidia graphics driver will not load when I start windows as a VM. Any ideas of what I can do to remedy the situation? Here is the current XML info that has worked well up until I booted into windows: <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm' id='1'> <name>Gaming Rig</name>

Yes, I did, in fact it can attach and detach successfully from other VM's just not this one. Again it was working before. I also tried deleting the lib XML and uninstalling the plugin and reinstalling also rebooting the unraid server. error: Failed to detach device from /tmp/libvirthotplugusb.xml error: operation failed: host usb device vendor=0x046d product=0x082d not found this is what i get when i hit detach

after improperly disconnecting USB camera I now get this error when I try to reconnect it to VM any ideas? error: Failed to attach device from /tmp/libvirthotplugusb.xml error: internal error: unable to execute QEMU command 'device_add': usb port 2 (bus usb.0) not found (in use?)
