ivshmem application in acrn

[jaslob]

I have two User VMs. One is RT Linux (yocto) and the other is Zephyr.
Now I want both VMs to use shared memory.
Like: https://projectacrn.github.io/2.1/developer-guides/hld/ivshmem-hld.html
Is that even possible in Zephyr?
Ivshmem works in RT Linux but I have problems in Zephyr.
How do I get the device ID and how do I read from the memory?
Is there a sample application I can work with to get an idea?
This is the only documentation I found:
https://docs.zephyrproject.org/latest/reference/virtualization/ivshmem.html?highlight=ivshmem#c.ivshmem_get_id
Thanks in advance.
