[OpenElec 5 VM]

you might want to take a look at somebody else who have sucessfully did it .

[[SOLVED] cannot passthrough usb device]

My lsusb result is as follows :

Bus 003 Device 003: ID 058f:6387 Alcor Micro Corp. Flash Drive

Bus 003 Device 002: ID 046d:c31c Logitech, Inc. Keyboard K120 for Business

Bus 003 Device 004: ID 413c:2501 Dell Computer Corp.

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

 

I tried adding

    <hostdev mode='subsystem' type='usb'>

      <source>

        <vendor id='0x413c'/>

        <product id='0x2501'/>

      </source>

    </hostdev>

Edit : The entry disappear as soon as saved it.

Scenario 2 :

I tried creating a new vm and add any usb device and i get

"Error: internal error: cannot parse vendor id 0x 003 Devi"

 

At the moment the kvm runs but i have no usb devices attached to it, thus no means of control.

I have gigabyte h87n-wifi motherboard.

According to the manual i have 6 x usb 3.0 and 4 x usb 2.0/1.1 ports. However when i tried all the ports at the back, it all connects to bus 3. I find this strange indeed. Hence i cannot do usb passthrough even if i wanted to.

I would appreciate some workarounds. Thanks

 

[Getting VM Manager plugin to install]

I tried the following steps

 

"Install the VM manager plugin:

Code: [select]

https://raw.githubusercontent.com/dmacias72/vmMan/master/vmMan.plg

Then install the Virtman Libvirt plugin:

Code: [select]

https://raw.githubusercontent.com/dmacias72/virtMan/master/virtMan.plg

Then go to the Settings tab and start the virtMan setting. "

 

I am stumped on the last sentence, cant seem to find virtMAn setting.
