And in other important aspects it's the same: it's still a single shared kernel and a single set of hardware resources. For that reason, I don't believe it's entirely wrong for users to want to be able to answer questions such as "what addresses are being used by this node?" There's a fair argument to be had for a _fully_ virtualized environment such as Domains or a paravirtualized one such as Xen that the global view either doesn't exist or is "hard" to obtain. I think it's very much harder for that same argument to hold when we're talking about a single instance of Solaris -- no matter how many network stacks are involved. Anyway, as I said at the beginning, I think making ifconfig work this way would be very hard to do, and likely would not work well. Though users often think of ifconfig as the sole way to interact with networking interfaces (because that's the way it works everywhere but Solaris), I don't think that's reasonably doable here, even if it's something that might be wanted. > We could try to hide this by pretending that (parts of) ifconfig > behavior is the same, but I'm far from certain that is a good idea. > > But the suggestion (made at PSARC) to use dladm to both > - assign datalink names to zones > and > - observe them (in e.g. show-link) > > is one which satisfies the consistency between manipulation and > observation.

The difference is that the zonecfg is just behaving as a repository for configuration that properly "belongs" to some other subsystem, rather than behaving as the configuration tool itself. (Yeah, there's a fuzzy line here as well.) -- James Carlson, KISS Network <[EMAIL PROTECTED]> Sun Microsystems / 1 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
