[Qemu-devel] Re: user-net -redir working?

[solution: use an IP address which isn't localhost, eg that of eth0] 3)Document this on the website as a known bug, so Google can find it. Currently, anyone using an earlier version will just think that qemu is broken. It hasn't worked since at least 0.6.1, although I can't tell you about earlier versions. > It should be google-able.

Unfortunately, searching for "qemu redir" or "qemu redir broken" leads mainly to copies of the manual, and to a couple of unanswered threads about people with the same problem. Can I suggest that this should be mentioned on this page: http://fabrice.bellard.free.fr/qemu/qemu-doc.html Thanks once again for your help, Richard ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel

So when it does a lookup for the host name, and it gets 127.0.0.1, it then all falls apart. I'm not sure how you can code around this particular problem. For those who say that the hostname shouldn't point to 127.0.0.1, that's fine. However, for my laptop, I'm constantly switching networks, and the software I use for that does it better than anything else I've ever used.

Most likely there is some issue with the slirp code dealing with the localhost construct. I suspect that the slirp code needs to be rewriting anything that has a source destination of 127.0.0.1 and map it some way. > 2)Fix it... :-) I haven't touched the code in a couple of months.

I know I've patched it with some code that Juergen Keil posted on the list a long ways back. Solaris generally installs with that DMA patch, and I think you may have to turn off acpi-enum=off at the grub prompt since the Bochs bios doesn't really speak ACPI.
