After rebooting, I want to create a PV guest with old method I had used in Xen 3.4.2. However, I got the following messages, and the creation failed. zhiyuan@zhiyuan-ThinkPad-R400:~/xen_work/images/rhel51-pv$ sudo xm cr -c 1-pv.cfg [sudo] password for zhiyuan: Using config file "./1-pv.cfg".

Especially compared with the 64M of RAM which you have configured the guest with. Ian.
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

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?
