What fields should be used for reporting shared memory?

Hi, I am going through the fields in the dictionary and I can't find any name to use for the following scenario. We (libvirt) are running virtual machines and there's a thing nowadays, that people like to use, called ivshmem (Inter-VM SHared MEMory). From host's point of view this is just a shared memory region accessed by multiple VMs (and possibly to host as well). The machine maps the shared memory given a name (e.g. name "asdf" results in /dev/shm/asdf to be mapped) *or* it can communicate with a server over UNIX socket and that server handles interrupts and also tells the client which shared memory region to map. Talking about information we have; in server-less setup it's the shared memory region that is shared, in the server scenario it is the socket. That's information we can output. So my question is, when starting a domain or hot-(un)plugging, what naming should we use for this kind of device and what are the things that we should describe about it? Basically, how would you like the message to look? Thanks in advance for any info. Have a nice day, Martin
