Hi everyone,

    I'm new to Xen. I printed some memory information of dom0 using printk() function in Xen and I want to get full message about printk. As I deploy Xen on laptop without serial port and vPro, I didn't have debugging environment.   When using 'xl dmesg', I can only get part of the information. I think the message may save in some place like log. Has anyone known the place?

   Or can I save the printk() message to a particular file by modifying some parts of Xen source code?

    Thanks for any ideas about this.

best wishes!
