I noticed this: https://github.com/qemu/libslirp/commit/5ac17660a76e321c37e6dca2e3c04d9d7d2b7ff4 So maybe slirp doesn't do DNS in quite the way I expect on MacOs.
In any case I couldn't figure out how to make changes to slirp and compile them into a new Qemu, I put a compile error into a file in the slirp directory and re-ran the top-level make and it didn't fail. I was going to just change the /etc/resolv.conf string to /usr/local/etc/resolv.conf and put my alternate address in there but I haven't figured out how to do that even.
