[libvirt] Channel with virtio problem

[norazah aziz]

But the problem on the channel, it happened when I put the code as below: 

        <channel type='pty'>
                <source mode='bind'
              path='/var/lib/libvirt/qemu/va-i5E36098H-virtio.sock'/>
                <target type='virtio'
              name='org.qemu.guest_agent.0'/>
                <address type='virtio-serial'
              controller='0' bus='0' port='0'/>
        </channel>

when I remove the code, the VM can up.

                          ^^^^^^^^^^^^^

This is your problem. serial targets don't accept a type attribute.
    Only channel and console character devices understand target type.
