Hello there,

I have new installed a debian lenny server(intel Xeon E5504, 4 cores) with 
xen(3.2-1) vms . A problem is when I reboot the serve(with domU status is 
"-b----"),  the domU will not get started automatically after the server 
booted.   But i can start those domUs by using the command "xm create 
myDomU1.cfg"  in the shell prompt with on error.

The domu can restart automatically orginially. But when i change some 
configuration, it now failed to restart. unfortunatelly i dont know which 
settings cause the problem.

I check the xend.log and found some error message(see below).

Anyone can help ?

The following information may help you to figure out the problem:

My configured domUs(I start them manually) :
