The deprecation message says: error_report("The -redir option is deprecated. " "Please use '-netdev user,hostfwd=...' instead."); How does this work for systems which have embedded ethernet devices and can't use -netdev ? This is one reason I haven't bothered to update my scripts yet (the other being that the deprecation message is basically saying "go and do a bunch of research into command line syntax" rather than "replace your current option '-redir xyz' with '-netdev user,hostfwd=x,y:z'"...) The message also doesn't point out that if you were previously using -net + -redir you need to switch to -device + -netdev, since -net + -netdev doesn't work AFAIK. Which is more upheaval to a working command line setup. thanks -- PMM

Of course it should work the same way as you currently can configure all embedded ethernet devices: -net nic -net user,hostfwd=...

I haven't tried, but I think you can also use: -netdev user,id=u1,hostfwd=... -net nic,netdev=u1 Or did you run into problems here? Anyway, looks like we really have to improve our documentation about "-net nic" ... yet another item for my TODO list (unless somebody else wants to have a try)... Thomas

Mmm, but the deprecation message doesn't say that. > By the way, I think our documentation is really lacking some proper > description how to deal with on-board devices ... > >> This is one reason I haven't bothered to update my scripts yet > > -redir is likely not doing what you expect as soon as you are using two > or more (embedded or non-embedded) NICs on a machine, so you really > should not use that option anymore. Two NICs on a machine is an obscure special case, though. Almost all setups will have just the one NIC. >> The message also doesn't point out that if you were previously >> using -net + -redir you need to switch to -device + -netdev, >> since -net + -netdev doesn't work AFAIK. > > I haven't tried, but I think you can also use: > > -netdev user,id=u1,hostfwd=... -net nic,netdev=u1 > > Or did you run into problems here? Nope. I just ignored the whole thing because the deprecation message didn't give me enough help and didn't actually stop anything working, and I knew that what the message did say was definitely wrong for my command line. I suspect I'm not an entirely atypical user here... I think what we need to do to be able to actually remove this code is: (1) make sure our documentation is clear and simple about how to move from an old command line to a new one (with examples, and covering all the conditions, not just the "let's assume everything's a PC with a pluggable PCI network card" case) (2) make the deprecation warning be specific, and cover all the cases, and probably refer to a documentation URL (3) make -redir in versions where we've removed the functionality print a message that specifically says "this option has been removed and is replaced by $FOO; see $URL for how to update your command line" (ie not just "-redir: unknown option", but retain the deprecation warning text for a bit). (Sorry if this feels like unexpectedly raising the bar for deprecation&removal -- I should probably have raised the issue earlier, but it was only your patch doing the removal that reminded me.) thanks -- PMM

Well, you could have at least complained during the 2.10 development cycle when we put all the deprecation stuff into place... But it's ok, this just showed me that there's at least somebody still around who uses the old parameters, and it also revealed that our documentation about how to configure on-board NICs is really bad. I'll try to come up with some patches that improve the documentation and the deprecation message, and then we can remove these options in QEMU v2.14 instead. The code for these options is rather simple anyway, so it also should not hurt that much to carry it on a little bit longer. @Jason: Could you please ignore this patch here, but queue at least the "-net channel" patch? I'm pretty sure that nobody is using "-net channel" anymore these days, so removing "-net channel" right now should be fine. Thomas
