Re: AW: AW: [Users] Multiple bridge support
I don't quite get it. Is it supposed to be a replacement for vznetaddbr,
an addition to it, or is it orthogonal to it? Who and when calls vznetaddbr?

How do you invoke it? Using EXTERNAL_SCRIPT?
Would be good to have a patch adding (conditional?)
invocation of vznetaddbr to vznetcfg.
One idea was to add a new global option in vz.conf:
DEF_BRIDGE=
If set, we automatically setup the bridge (we need to pass an additional
parameter to vznetcfg, but i guess thats no problem at all). That also
avoid a hardcoded default bridge name (vmbr0).
Here is the totally untested code. If you like the idea I will test it
;-)

I don't quite get it. Is it supposed to be a replacement for vznetaddbr, an addition to it, or is it orthogonal to it? Who and when calls vznetaddbr? It merges vznetaddbr into vznetcfg, making vznetaddbr obsolete. - Dietmar ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
AW: AW: [Users] Multiple bridge support
It would be just great if you can provide a patch to vzctl man page describing the new parameter, and the according wiki modifications/additions. Here is the patch for the man page. I am not sure how to edit the wiki. Howto indicate that the feature is only available in newest version from git. Can I use 'version 3.0.22' ? - Dietmar vzctl.8.diff Description: vzctl.8.diff ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
