It was working with xen 3.1 on mandriva 2007.0 (prior to update), and 
failed with xen 3.1 on mandriva 2008.0 (after update). And the guest was
Windows XP, 32 bits.

This happened on 64 bit linux.

Strangely, everything works OK now after a reboot, a minor update of xen 
package (just adding squashfs support), and a different ordering of 
network configuration at startup (no more explicit bridge setup before 
launching xend). My assumption is that xen is over-sensible to current 
network configuration: if you ever have a misconfigured interface or 
bridge, strange things may happen, such as already reported at:
