OK, I changed the "memory" line to 800, but, seems it does not work also:

zhiyuan@zhiyuan-ThinkPad-R400:~/xen_work/images/rhel51-pv$ sudo xm cr -c 
1-pv.cfg
Using config file "./1-pv.cfg".
zhiyuan@zhiyuan-ThinkPad-R400:~/xen_work/images/rhel51-pv$ Error: Device 
2049 (vbd) could not be connected. Path closed or removed during hotplug 
add: backend/vbd/1/2049 state: 1
and quite silently .....

But I am very sure the disk image path is correct. And tried also to 
change "sda" to "hda" the result is the same.
I also attach the .config file for the pvops kernel with this email. 
Should I compile another kernel for the PV domUs?


Thanks!
Zhiyuan
