Xen devel - Jul 2013 - How can I get the output information of DBGOUT?

Hi all,
   I am trying to debug the e1000 driver on xen. However, I have no idea about
printing messages for e1000.c. I found some functions use the macro DBGOUT. I
wonder how to get the messages of this macro.

If you are talking about the DBGOUT in qemu/hw/e1000.c then by looking
at the code it seems like they come out on qemu''s stderr, which libxl
redirects into a file under /var/log/xen/. You will need to set
debugflags to include the class of message which you are interested in
as well.
