I have determined, by the way, a much more precise location for the bug. I can start a Knoppix image, which can reliably resolve hostnames, and ping the host machine. I then tried a http-over-telnet, to test TCP. I connect, send/receive data just fine. The moment I Ctrl+C the telnet, that's when qemu dies. So I suspect the bug is related to the TCP close code. I shall investigate further... --=20 Paul "LeoNerd" Evans leonerd@leonerd.org.uk ICQ# 4135350 | Registered Linux# 179460 http://www.leonerd.org.uk/ --G4iJoqBmSsgzjUCe Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFC4BnKvcPg11V/1hgRAjIPAJ0c0yy+0jakwOJzA2xTnIcd4yo8QwCfTFZv YsjJORoL3h8Wi6f9p/Xf4sE= =IN5s -----END PGP SIGNATURE----- --G4iJoqBmSsgzjUCe--
