The good news is that you have identified most places and have the cleanup functions already so it’d be a matter of transforming your changes (assuming they are correct and working fine; haven’t actually read the patch in detail;-)  to the different infrastructure.  And that’s the easiest part.

Hi Bjoern,
Thank you for your reply.

The "common" VIMAGE framework sounds good, I really want it.

I want to know what the IPC system looks like for user-land after virtualized,
and what happen if vnet like vipc is implemented.

For example, jail 1, 2, 3 join vipc group A, and jail 4, 5, 6 join vipc group B ??
Hmm, it looks good.
