I want to assign my own character device to guest. I tried going
through code and found -chardev option.-chardev defines several
backend options but I could not understand how they interact with
guest. I also tried to search online but I got information mostly
regarding pci device assignment. Could anyone please help me with
this? Is there any documentation regarding character device
assignment?
Thank You,

There is no such thing as character device assignment, since it doesn't
correspond to a single device bus. We support assigning usb and pci
devices.
What device are you trying to assign?

Sorry for the late reply.I was trying to export a file as a device in
guest vm which can be shared on second guest vm. So i was thinking of
exporting as character device and so I was trying to find out how this
can be done . But later I found about ivshmem which allows us to do
the same.
Thanks for reply.
