Just to clarify - you mean try to run the installer using a qemu VM
as the target for installation? I can certainly try that.
More details.
The target system is pxe booted and next-server takes it to a (debian)
system running tftpd-hpa. The defaults.cfg has lots of boot targets
but the one I have been testing with is the netboot image, in manual
install mode. The only boot options it is given are
'append vga=normal initrd=yadayada'
It also falls over if I feed it a preseed file, where we use
'append auto=true priority=critical vga=normal initrd=yadayda
url=blahdeblah'

I tried to wget pages from a few web sites from the alt+f2 console.
It segfaulted every time when I used a DNS name in the URL,
but worked if I used an IP address in the URL.
ping does the same thing; segfaults only when using domain names.
If I put an entry in /etc/hosts and try to access that hostname,
wget and ping also segfault, until I add this line to nsswitch.conf:
hosts: files dns
Then they both work for that hostname.
The only other nsswitch.conf lines are for passwd, group & shadow.

Ok that's good to know.
