@jp13232 Good Question. You found an answer as yet ?

I'm using XCP-ng and except for requiring the testing repo, (specifically only for NUT), it's working perfectly. The package name is a bit "non-standard".

yum --enablerepo=* install nut.x86_64

The UPS is connected over USB and on a power failure, the hypervisor shuts all the VMs gracefully down with a simple "shutdown -h +0" specified in upsmon.conf.

@hannes_5253 Any reason for not prefering to run the NUT server directly on the XCP-NG host ?

@olivierlambert I wouldn't know where to start

I have 2x external USB3 drives I'd prefer passed thru to a specific VM.

With XCP-ng Center it's quite simple once one is aware of the navigational routes. That being

• "General > Properties > USB > Attach" once the device has been passed thru, and
• "Storage > Attach Disk" if not.

However, it seems undoable via XOA...

i.e. How would one go about to accomplish the following in XOA:

• enable passthru for USB device
• assign USB device to VM

or

attach USB storage to VM (without enabling passthru)

In addition, I also found that the USB devices list and can be attached in XCP-ng Center, yet would not list in XOA ("VM > Disks").

If they are passed thru and attached to a VM (via XCP-ng center), they then do not reflect within the VM...

Here's another willing script tester
