KVM Plugin - Remove USB Device from VM not possible

  • I am using a windows vm and attached actually three usb devices to vm. When I try di remove one usb device from vm an error message is thrown from virsh on command line.


    Failed to remove USB device.

    error: Failed to detach device from /tmp/virsh_usbn4uXED

    error: XML Fehler: Invalid value for attribute 'id' in element 'vendor': '0x'. Expected integer value

    Seems some problem on plugin creating command line skript.


    Is it generally possible to remove usb device on running kvm vm? Actually I shutdown VM but removing is still not possible. May be manually removing from vm xml file will be successfull.

    Is it generally possible to remove usb device on running kvm vm?

    Yes. Did you add the usb device with the plugin? It is evidently parsing the usb device incorrectly. Can you post the VM's xml?

  • Yes. Did you add the usb device with the plugin? It is evidently parsing the usb device incorrectly. Can you post the VM's xml?

    Yes actually all three devices are added via kvm plugin gui. As I needed the vm I manually removed from XML File the entry for this usb device and I could start my vm again.


    I will test again and send you the VM xml and try to reproduce the issue.

  • Attached you will find my XML File from the VM. Tested once again and online removal of usb device is not possible. Seems that the constucted xml file has some missing data for the complete pci string for the usb device:


    Code
    <hostdev mode="subsystem" type="usb" managed="yes"><source><vendor id="0x"/><product id="0x"/></source></hostdev>

    It is failing to parse the vendor id. I'm guessing something is weird with your usb device. What is the output of: sudo lsusb

    What do the entries in your dropdown when removing the USB devices look like?

    I will have to try this on my server when I get home. Hopefully I reproduce this.

    Not sure what broke then. You could use virt-manager or virsh too. The plugin uses virsh but somehow the vendor id is not making it from the dropdown to the virsh call.

    Removing usb devices should work in 6.1.22 in the repo now.

  • Hi, I have the same issue.


    Yesterday I setup a VM with Home Assistant Operating System. So far so good. Now I attached my Home Assistant SkyConnect USB Stick (ZigBee/Thread Connectivity) via the KVM Plugin and it was recognized in the VM.


    But I am absolutely new to Home Assistant. So I worked with Snapshots. After some misconfiguration I went the route to go back to an earlier snapshot of that vm. But I had another issue and decided to delete the vm including its snapshots and recreated the vm with the qcow2 file.


    But now its not possible to add the Home Assistant SkyConnect again. I see messages like the following in a red box:


    Code
    500 - Internal Server Error
    Failed to add USB device. error: Failed to attach device from /tmp/virsh_usbXQcqvY error: Angeforderte Operation ist nicht gültig: Einheit ist bereits in der Domain Konfiguration vorhanden virsh attach-device --domain haos --file '/tmp/virsh_usbXQcqvY' --persistent --config --live



    Code
    root@omv6:~# cat /tmp/virsh_usbXQcqvY
    
    <hostdev mode="subsystem" type="usb" managed="yes"><source><vendor id="0x10c4"/><product id="0xea60"/></source></hostdev>

    It is this devices:


    Code
    lsusb
    ...
    Bus 001 Device 004: ID 10c4:ea60 Silicon Labs CP210x UART Bridge
    ...

    My vm.xml looks as follows:



    What exactly do I have to change or delete in the vm.xml file? The relevant part seems to be this:

    Code
        <hostdev mode='subsystem' type='usb' managed='yes'>
          <source>
            <vendor id='0x10c4'/>
            <product id='0xea60'/>
          </source>
          <address type='usb' bus='0' port='4'/>
        </hostdev>

    Is it as simple as removing the complete part or only parts of it?


    Thanks Hoppel

  • Hm...


    So I did the following:


    • stop the vm
    • deleted the following part of the vm.xml
    Code
        <hostdev mode='subsystem' type='usb' managed='yes'>
          <source>
            <vendor id='0x10c4'/>
            <product id='0xea60'/>
          </source>
          <address type='usb' bus='0' port='4'/>
        </hostdev>

    --> It doesn't work! Still the same issue:


    Code
    500 - Internal Server Error
    Failed to add USB device. error: Failed to attach device from /tmp/virsh_usbIsJpae error: Angeforderte Operation ist nicht gültig: Einheit ist bereits in der Domain Konfiguration vorhanden virsh attach-device --domain haos --file '/tmp/virsh_usbIsJpae' --persistent --config --live
    Code
    cat /tmp/virsh_usbIsJpae 
    
    <hostdev mode="subsystem" type="usb" managed="yes"><source><vendor id="0x10c4"/><product id="0xea60"/></source></hostdev>


    So, I decided to try the following:

    • stop the vm
    • deleted the snapshots of the vm
    • ls /etc/libvirt/qemu/ the file vm.xml is not there anymore
    • recreated my vm with the same qcow2 file
    • added the usb stick -> YEAH!!!! THIS WORKS!!!! :)
    • started the vm -> Yes, it works!

    Anyway, thanks! ;)

    You probably should always delete snapshots when adding hardware.
