Re: Shared memory usage

Dear Users, I tried out shared memory using libvirt. When I configure it in the XML (ivshmem-plain), I have to provide a name for it and after starting the VM I can see the appropriate file on the host in the /dev/shm/ directory. My problem is that I could not find any official documentation about the usage of that shared memory. On the guest side, I have found the PCI device related to it, but I do not know how to use it. Is there any available command line tool to read from or write to this memory or is it only possible with a user application? Could you provide my what is the most common solution for this?
