Hello virtio-dev team, I want to compress all the data or files when the apps in VMs writes to a pass-through block device via kvm virtio. And decompress the data when the apps in VMs trying to read the data from the pass-through block device on host.
My idea is to add a data transform layer into virtio architecture for the purpose of transparent compress. I am reading the virtio.c, virtio_ring.c code, but have not found the place where I can do the data compress. Is it feasible that we can add a filter into the virtio, and there is a chance to do data compress or encrypt in the filter? Thanks Keen
