...nter from Xen (22 = Invalid argument) This routine is based on the specification of the trace buffer control function trace.c/tb_control(). The function checks the trace buffer is initialized or not in line 183. If not, this routine stops working. Of course, this problem is also solved by using tbctl [0|1]. But this problem is already solved by xenmon.py without using tbctl command. This code is just moved from tools/xenmon/xenbaked.c(get_tbuf and misc settings) I hope these two tools (xenmon.py and xentrace) share the functions.

Hello, I have a question about the way Xentrace takes a trace. In previous versions of Xen, I took a trace by setting the size of buffers, activating them and writing the information into a file (optional). setsize 20 tbctl 1 xentrace /tmp/xentrace.dat Now I''m using xen-unstable and I see that setsize is already integrated in xentrace command. My question is: does start/stop buffer is integrated into the xentrace too? I mean, does xen write trace information into buffers by default or it starts writing th...

Nice time. # make uninstall ... rm -rf //boot/*xen* ... if somebody use "xen" in kernel name (maybe as suffix), so it will be deleted from /boot/ too. Thanks. Denis.

Hello, I''ve been trying to get xenmon.py and xentrace to work, but I consistently get the following (on a couple of different machines/kernels): kibab kibab # xentrace /root/xentrace.log ERROR: Failure to get trace buffer pointer from Xen (22 = Invalid argument) Did I miss an option that has to be turned on or something? Is there some other setting that I need so that everything

Hi, I am using xen-unstable and interested to trace the hypervisor. In previous versions, I was able to trace it by: setsize 20 tbctl 1 xentrace /tmp/xentrace.dat And these functions don''t exist in xen-unstable. xentrace --help shows that in more recent versions the buffers'' size could be determined as a parameter for xentrace. But I can not find any replacement for tblctl. Using: # xentrace /tmp/xentrace1....

...ace buffer region is already allocated or not by using xc_tbuf_get_size. But This solution problem remains, 1) It cannot change the trace buffer size by using xc_tbuf_enable If we do, we need to add more code to freeing xen buffer. As other option.(at application layer) Adding previous command tbctl. This command switches tb_init_done =0 and 1. Comments are appreciated. This problem occured in following steps. 1)xentrace tb_init_done = 1 2)xentrace (problem occured at xc_tbuf_enable see above) After xentrace work, this problem occured.
