XCP-NG Randomly forgets USB Passthrough

[Trufax]

Hello,

iam running XCP-NG 8.2.1.

Iam using USB passthrough for multiple devices. Since some time the system Randomly "forgets" the passthrough. It usually happens when the host reboots but also when the VM itself reboots. The status in the XCP-NG Center is than "Disabled" as if the devices would have never been passthroughed in the first place. I have to enable, shutdown the VM and passthrough again.

I use the offline Backup feature for the VM so backup can happen when USB devices are passthrough, maybe the reattachment is not working reliably ?

The devices are plugged in the whole time, i also changed USB Ports with no difference.

Regards

Hi,

It would be better to open a thread on the community forum and also trying to dig on the logs to see if you can spot something :)

Having this same issue Trufax. It seems like it was addressed in issue 164, but with no resolution. I currently have no backup tasks, or snapshot tasks and find this happening once every 1-2 days.
