I guess I finally figured it out, the test binds IPv4 and on the NetBSD
VM, 'localhost' resolves as IPv6 so the guest can't connect to the test.

I'm not sure what's the best way to fix this (yet), meanwhile the tests
succeed using:

-- >8 --
     global_qtest = qtest_initf(
-        " -chardev socket,id=ipmi0,host=localhost,port=%d,reconnect=10"
+        " -chardev socket,id=ipmi0,host=127.0.0.1,port=%d,reconnect=10"
         " -device ipmi-bmc-extern,chardev=ipmi0,id=bmc0"

Phil.
