Hi all,
I need a mechanism to share memory between my kvm guests to use at an
intrusion tolerance project. I found the Inter-VM Shared Memory
(ivshmem) device driver posted in this mailing list. I am trying to
install and use it, but I have some questions.
Is there a documentation (like a roadmap) about how to put ivshmem
device driver to work and how to test it?
Hi Valdir,
Documentation is under development. I have some simple test programs
that I can supply when you get it up and running. As well as boot
scripts to create the /dev file.
I've compiled the patched kernel with ivshmem enabled as a module.
Now, I'm running kvm over this kernel. So, what is the next step?
I've tried this on my kvm guests:
num =`cat /proc/devices | grep kvm_ivshmem | awk '{print $1}`
mknod --mode=666 /dev/ivshmem $num 0
But, the /proc/devices file has no reference to kvm_ivshmem.
Are you running the patched kernel on the host or in the guest. It's
meant to run in the guest.
