If "path" for "ivshmem" memory device is specified, it's going to be setup with interrupts enabled. Otherwise interrupts is disabled. To be more clear, let's see the QEMU command line of both cases:
* With interrupts (/tmp/nahanni is the ivshmem server socket path)
/* This starts the ivshmem server */ % ivshmem_server -m 512 -p /tmp/foo
/* qemu command line */ -chardev socket,path=/tmp/foo,id=nahanni -device ivshmem,chardev=nahanni,size=512m,vectors=8,ioeventfd=on
* Without interrupts (no ivshmem server is needed) -device ivshmem,shm=nahanni,size=512m,vectors=8,ioeventfd=on
I think <doorbell/> is a better name than ioeventfd. That is somewhat kvm-specific, but there's no reason for it to be. Paolo
