Hi all,

I am using Xen 3.0.3 testing version and would like to know the way to pass information from Xen hypervisor to dom0 userspace application. I am intercepting some domU events in the hypervisor and using printk to print that information. Then, I use "xm dmesg" to see the output of printk statements.

Instead, I would like to pass this information to dom0 userspace application, which can store and process this information.

It would be great if someone could tell me how to pass this information from hypervisor to dom0 userspace.
