VUSB keeps disappearing
-
I have a VM that only has NUT installed. I have a VUSB for my CyberPower UPS that passes through to it. I've noticed that the VUSB keeps disappearing. A couple of days ago, I noticed that PeaNUT was reporting that NUT was offline. I checked this VM, and saw that the VUSB had not just disconnected, but it was completely unplugged as well. I thought nothing of it, shut down the VM, added the VUSB, and booted again.
Today I just noticed the same thing. The VUSB does not even show in the list of VUSBs in XOA. Now, I'm certain you'll tell me that the physical USB disconnected or something. I'm sure that this is the expected behavior in that scenario. But that definitely didn't happen. I just want to know what I should look at to troubleshoot this? How can I see when a VUSB disconnected, and maybe figure out what steps led to that?

@nuentes Same issue here. I have 6 Cyberpower UPSs all attached to different VMs for monitoring. Theyre all disconnecting randomly. This did not happen before I updated XCP in the last couple months.
And I know all 6 of them are not being physucally unplugged haha.
While I have no solutions for you, I hope this gains some traction as its severely messing with my Energy monitoring.
If you still want a way to know when it “disconnects”, I would recommend installing Powerpanel on the VM you’re using with the UPS, as it will log when communications are lost… However knowing when it happened won’t help you solve it unfortunately…
BUT if you have a mail server, you could set it up to send you an email when comms are lost
