Mark, I tried it, but still failed.
If I use bootloader="/usr/bin/pygrub" and kernel ,ramdisk paramter,
HjCloud:/mnt/winimg/xen_vm_config # xm cre kernel=/mnt/winimg/xen_vm_config/sles11sp2_iso_boot/vmlinuz-xen ramdisk=/mnt/winimg/xen_vm_config/sles11sp2_iso_boot/initrd-xen sles11sp2pv
Using config file "./sles11sp2pv".
Error: Boot loader didn't return any data!
so , I commented the bootloader line ,vm's conf is as follows ,but failed too, I got the screenshot in the attachment.
meanwhile , I find
http://www.gossamer-threads.com/lists/xen/users/187703 , maybe for pvm , boot from cdrom is impossible ?
thanks !
