Anyone have any recommendations on how to limit the bandwidth for a domU,

help would be greatly appreciated.
The Linux tools http://lartc.org work well (we've used hierarchical token bucket
mostly). You can treat the domains just like any other computer behind a
bridging firewall/bandwidth limiting node. Looking at concrete examples was
helpful to me when I was first looking at it, e.g., search for htb tc linux
Code was just committed to -unstable that does this (outbound only):

Plumb network vif credit-based rate limiting thorugh xenbus
and xend into xm guest config files.
A new vif parameter 'rate' is supported, with an optional time window
paremeter for specifying granularity of credit replenishment. The default
window is 50ms. For example:
'rate=10Mb/s' 'rate=250KB/s' 'rate=1MB/s@20ms'
Thank you,
