[Martin Husemann <martin%duskware.de@localhost>]

Hi folks,

I tried to boot the latest netbsd-7 amd64 install CD on xen and it fails
miserably:

You are using a serial console, we do not know your terminal emulation.
Please select one, typical values are:

        vt100
        ansi
        xterm

Terminal type (just hit ENTER for 'vt220'): xterm
[1]   Abort trap              ${cmd}

To return to the installer, quit this shell by typing 'exit' or ^D.

Most commands work, the failing command is /sysinst.

The install CD image works fine on other machines. Does this ring a bell
for anyone?
