I do not think that this is possible without an additional device in the
UML itself.
In fact, if you want two processes in two different UML instances to
communicate in-between themselves you should aim at a UML device. The
kernel device is probably suprlus to requirements as the two UML
instances can communicate between themselves within the host userspace
using any of the mechanisms available for that.

Hi:
I wrote an IPC mechanism as a Linux kernel module. The access
to their services is through a dummy character device called /dev/dvk
using ioctl(). Therefore, only open(), ioctl() and close() system
calls are used.
How can a process running within an UML Guest access the
/dev/dvk host device? (humfs??)
The idea is to communicate two o more UML instances through
this IPC mechanism.
Thanks in advance.
