I am trying to configure a virtual CAN device (vcan0) on qemu and I have followed the below steps:

1. modprobe vcan
   ip link add vcan0 type vcan
   ip link set vcan0 up
2.  Updated in /etc/dev-mapping.conf  file from hs="can0" to "vcan0"
   hs="vcan0"
   ls="vcan1"
3.  Running candump vcan0

On other qemu terminal -

1. low-can write { "signal_name": "engine.speed", "signal_value": 1256}

But still the data is transferred through can0 and not vcan0.

candump vcan0 doesnt shows any data. I want to understand how can I tranfer can-data on new device.

Que : Can I add multiple Virtual CAN devices for hs and ls ?

ex : hs = "vcan0","vcan1"

       ls = "can0", "can1" <--------something like this
