>Description:
When doing an install in NetBSD 5.1, QEMU without TAP-interface cannot use ICMP (ping) and thus assumes the network is down, when in reality it is not. There is an option to continue the install, but if not read throughly, the user may assume the network does not work at all. 
>How-To-Repeat:
Install NetBSD 5.1 on QEMU and set up the network.
Fails on pinging the host.

>Fix:
Either adjust the install to accommodate for QEMU or not use ping as a part of network detection.

 Slightly on a tangent: do you use dhcp to configure your network?

 I think a reasonable change would be to drop the ping test if we get
 the network autoconfigured, but still do it on manual setup (as a
 double check for the entered data). If the ping does not work, the user
 can thing twice and choose to ignore the ping failure - or fix the
 configuration data.

 Which version of qemu did you run and how exactly (command arguments)?

 Unfortunately, his mail's bouncing.

 I'm sure this is not a problem of NetBSD or qemu.
 It is a documented feature of the user mode networking of qemu
 the submitter probably used.

 Yes, that seems likely. All the same, I guess it's a bug for NetBSD to
 not install cleanly in an environment that can't ping.
