Kernel compilable as:

• VIMAGE_GLOBALS – no indirections

• default – virtualized variables in global structs

• VIMAGE – virtualization structs dynamically allocated

• Management API merge from p4 vimage branch – will allow for vimages to be created / deleted / ifnets reassigned

• Interim solution only - will be superseded by new jail framework when ready.

• Many subsytems not touched yet but on todo list: SCTP, NFS, pf / ALTQ, dummynet, mroute…

• ifnet ↔ devfs interaction

• version checking of vnet container layouts at both compile and run / kldload time, without overloading FreeBSD_version, preserving KBI during major releases but without having hands tied for extensions

• virtualization (not only vnet) of PCPU state

• per-vnet vs. global uma zones for various stuff

• mbufs: per-vnet or global pools / accounting etc.

• bailing out of vnet initializations that fail due to resource shortages

• getting rid of kldsym / kmem legacy in network stack

• dealing with TOE NIC hardware

• API for controlling remote vnets

• performance
