I have been having issues where my HomeAssistant VM will run well for several days. At some point the Zigbee USB stick will no longer be detected (or it has an error accessing it, HomeAssistant states "Could not open port ... no such file or directory" I've attached a screenshot). 

 

I recently moved the pools on my cache drives, which my VM was on, from btrfs to zfs by moving all data to the array, reformatting, and moving the data back. This error has been happening since then, but everything else on the drive (docker) is working as expected.

 

I also see these logs in USB Serial Manager plugin since for this device I need to set it to "Connect as serial only"

During my zfs move, I did have issues moving the "/user/system/libvirt/libvirt.img" file, and found a post saying that it would likely be safe to remove as it would be recreated. Which it was, but I'm not sure if that is the reason these errors started.
