But I have another question, how do I debug in the Xen hypervisor side?
Just "printk" ?
Connect something (e.g. another computer) to the serial console,
and boot Xen with serial console enabled.
As well as printk, Xen has a GDB stub. This is quite powerful,
and can be used for debugging domains and processes too.
However I could not find out any print message in /var/log/message and the
xen_read_console ?
"xen_dmesg.py" in dom0 will show you the console output from
*Xen*. (//var/log/messages and xen_read_console are domain
console tools).
For any serious debugging, get yourself a serial line. xen_dmesg
isn't much use if either Xen or domain 0 are already blown to bits.
BTW: What does your new hypercall do?
