I've never been able to get tap:aio: to work for hvm under fc8 either. tap: 
used to work under fc7, but even that doesn't on fc8 anymore. For the 
network, eth0 is the default *bridge* under fc8. In your case, with the 
physical eth0 & 1 disabled, do a 'brctl show' and find out which bridge 
has 'peth<n>' attached (probably peth2), and then put ', bridge=eth<n>' in 
your hvm's config. (No need to change xend-config.sxp.)
