Subject: [kvm-ppc-devel] Profile kvmppc - #2 - guest idles two minutes in
Date: Fri, 04 Apr 2008 11:03:58 +0000 [thread overview]
Message-ID: <47F60B1E.6060802@linux.vnet.ibm.com> (raw)
Well without real perf counters it's semi-useless (might be misleading) but anyway here what I got so far - #2 - guest idles two minutes in shell prompt:
bash-3.00# opreport --session-dir=/mnt/usb/oprofile_idle/
CPU: CPU with timer interrupt, speed 0 MHz (estimated)
Profiling through timer interrupt
TIMER:0|
