Wine is one of those badly behaved glibc negative segment offset programs. 
It's painful enough waiting for it to load in dom0. I'd hate to see what it 
does in a domu. Still, if you have time to follow Nico's suggestion, might be

If you want to debug this further, post your hvm config. The way sdl grabs the

Look at 'brctl show'. You may have dom0's eth0 as a bridge, which fc8 (and any 
modern 3.1.x xen) does, and may have to change your hvm vif's bridge 
accordingly, at least as a test.

Somebody correct the syntax if this is wrong, but appending 'console=tty 
console=xvc0' to your domu's grub's kernel line may help.
