[xenpreview-dev] SLES 10 Beta 8 and xenmon.py not running

[Thorolf Godawa]

Hi,

today I installed SLES 10 Beta 8 (i386) on an old AMD 1,3GHz.

The installation went through very smooth, I didn't found the problems I 
had in all betas before.

XEN also is running quite good, the Linux VMs now are much more stable, 
even with CPU- and network-load - with Beta 3 the whole host-system 
often crashed when I generated network-traffic from a domU.

But since Beta 4 I have an other problem, the Python-script "xenmon.py" 
not running for analysing CPU-usages via xenbaked is not running anymore.

If I start it I get the following error:
----------------------------------------
lx-xen:/usr/sbin # python xenmon.py
xenbaked: no process killed
ms_per_sample = 100
Initialized with 1 cpu
CPU Frequency = 1303.00
ERROR: Failed to mmap trace buffers (14 = Bad address)
----------------------------------------

And instead of showing s.th. about the processor-usage I only get the 
"blank" table:

----------------------------------------
  CPU = 0        Last 10 seconds                        Last 1 second
  =====================================================================
                    0.00%                                  0.00%

----------------------------------------

Do you have any idea what's goinig on there? Is there an other 
possibility to get the actual CPU-load for every CPU into a 
Python-script instead of using the shared memory with xenbaked (s.th. 
like "xm top" is using)?


Thanks a lot for any answers in advance,
