lvm cache + qemu-kvm stops working after about 20GB of writes
...o everyone, Anybody had the chance to test out this setup and reproduce the problem? I assumed it would be something that's used often these days and a solution would benefit a lot of users.

...ou want with Shorewall. It looks complicated, but actually is very intuitive if you give it some time and effort. Please feel free to provide a better description of what you want to accomplish.
