Your private changes for HEAD might be screwed by the the of this day (BST) as the first step of the VImage work should go in. You have been warned, we are going to accept the risk, talk to Peter in case you want to stop is this or sink the Isle of Albion within a few hours;-) /bz PS: if you are unlucky we'll prepare the 2nd stage for/on Monday. -- Bjoern A. Zeeb Stop bit received. Insert coin for new game. ---------- Forwarded message ---------- Date: Sun, 08 Jun 2008 22:58:40 -0700 From: Julian Elischer To: FreeBSD Current , freebsd-virtualization@freebsd.org, Marko Zec Subject: kinda headsup.. At the BSDCAn devsummit we discussed how to proceed with committing Vimage to -current. the Milestones included something like: June 8 (today) Headsup.... June 15 commit changes that add macros for vnet (network module) and vinet(inet virtualisation) with macros defined in such a way to make 0 actual differences. provable by md5 etc. Documentat s/hostname/g//V_hostname/ #define V_hostname hostname 2 weeks settle time, next step prepared, tested and reviewed. June 29 Add changes to convert all globals to members of per-module structures. Done in a reversible way (i.e. compilable out). Macros defined so that depending on compile options structures or globals are used (one global structure). Performance implications of using structures are evaluated. Structures possibly tuned. Initialisation routines added, checked and tuned. example: #if VIMAGE_USE_STRUCTS #define V_hostname sys_globals.hostname ... #else #define V_hostname hostname ... #endif July 13 globals removed in vnet, vinet. ifdefs and compile option removed or scaled back to make code clean to read again. Destructor routines added where needed. Remaining "NULL Macros" (compile to nothing at this point) committed to reduce the size of the MEAT diffs. Review of Meat diffs formally under way for final comment. example: #define INIT_VNET_INET(x) /* nothing */ add "INIT_VNET_INET(curvnet);"(and similar) where needed. remove globals (e.g. 'hostname') July 21 JAIL+Vimage framework committed. e.g. add new syscall, program, etc. (part one of meat diffs) structures still only global instances. vimage inhansed jails can be created but act jus tlike normal jails? July 28 Ability to created > 1 vimage enabled. Vimage enhanced jails now have private network stacks etc. August start on converting more modules as needed and time allows. Marko and I have been working towards splitting up the current diffs (which do the whole thing) so allow this schedule to be followed. We may or may not be ready for the June 15 step by then, but if not it may be a week there-after. So this should be considered the heads-up. discussion will be on freebsd-virtualization@ and the perforce branch that we have as a current working system is branch 'vimage'. //depot/projects/vimage/... diffs can be found at: http://www.freebsd.org/~julian/vimage.diff and it are usually fairly up to date. _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
