[Xen-devel] How to enable debug information?
Hi Everyone,
I am a newbie to the Xen. I want to understand how the blktap disk works. I found out the following files under:
tools/blktap/drivers/tapdisk.h tapdisk.c
where it has the definition of 'DPRINTF'
/*If enabled, log all debug messages to syslog*/ #if 1 #define DPRINTF(_f, _a...) syslog( LOG_DEBUG, _f , ## _a ) #else #define DPRINTF(_f, _a...) ((void)0) #endif
My question is how to enable the debug so that debug message can be sent to syslog? Which log file should I look into?
Thanks a lot.
Jim
