[Xen-devel] how to trace scheduling overheads using xentrace/xenalyze

["Yu-An(Victor) Chen" <chen116@xxxxxxx>]

Hi,

I am new to xen environment and I am wondering how to trace scheduling overhead of guest vm using xentrace/xenalyze ?

I have tried using $xentrace -D -e all -S 256 {filename}

and then use various xenalyze options but most of them gave me empty result, and I dont really see where I can get scheduling overhead so I can see how are the jobs are scheduled and its execution time and stuff. Please point me to a direction. Thank you!

Victor
