    Hello,
    First, please verify that you installed Xen using the YaST Virtualization "Install Hypervisor and Tools" module" -- Or if you didn't do that describe your method of installation.

    And,whether your Guest is HVM or PVM.

    Thank you for your interest. My configuration is vm. After adding the device, the usb vm switches off. And he does not answer the call

    Default Re: attach usb to xen vm problem

    Because your virtual machine disk file isn't in an expected location, I'm pretty sure you did not isntall Xen properly.

    Open YaST (which should be almost a reflex for doing anything in openSUSE, using YaST as your first option to install, configure and manage everything on your machine will generally give you s working configuration with known default values).
    Look for a module called "Install Hypervisor and Tools" and open that.
    You should see some screens which allow you to select your virtualization choice (Xen will be an option, and should also select the User mode tools) and continue.
    YaST will then install Xen, libvirt which is the graphical managemant tool (and has its own command line environment), and offer to set up a bridging virtual bridge device called br0. accept everything that's offered.

    Reboot, and then create a new virtual machine (My guess is that your old virtual machine will more trouble than it's worth to try to import).

    Also,l if you're new to openSUSE you may find the slide deck to a presentation I give on openSUSE 15.0 helpful, it describes most everything a User should know and do from pre-installation to first steps after install.

    Post Re: attach usb to xen vm problem

    When there is no hostdev entry with usb the machine is working properly.

    I checked it on 3 computers and the problem is the same. There may be a missing module in the kernel or system permissions.
    I tested on opensuse Leap 42.3 and Leap 15
