Hello all I am very much new to the world of KVM and Qemu. I am trying to make a communication possible between the Guest and the Host. I have studied how Virtio works but I am still confused how exactly the flow will work.
The
front end drivers will communicate to the back end driver by invoking a
kick function, but which back end driver will be involved in that.
Also how the back end driver present in the Hypervisor will pass this information to the emulated device running in Qemu. I
am trying to use virtio_pci.c and some suitable modification, so that
the back end driver can take that information and that information will
be available to the Hypervisor.
It will be very useful if somebody can provide me the working code of the virtio_pci with all the dependencies in the separate directory, so that I will be able to insert that module and the equivalent back-end driver code running in the Hypervisor.
