'Floating point exception' with Haiku disk image

I’m trying to use Haiku with Qemu running on Ubuntu. I get the following message:

george@george:~$ cd DiskImages/ george@george:~/DiskImages$ ls haiku.image newos.img reactos.img george@george:~/DiskImages$ qemu haiku.image warning: could not open /dev/net/tun: no virtual network emulation Floating point exception george@george:~/DiskImages$

I can use ReactOS, Syllable, and NewOS without getting this problem, so I don’t get why it’s happening with Haiku. Has anyone got a solution?
