My assumption would be no but I came across this in one of the errata notes which suggests running it in a Xen guest? 1.118.1. RHBA-2010:0247: bug fix update An updated mcelog package that restricts mcelog operation on para-virtualized guests running under the Xen hypervisor is now available. mcelog is a daemon that collects and decodes Machine Check Exception data on AMD64- and Intel 64-based systems. This update addresses the following issue: * in some circumstances, mcelog can run on para-virtualized guest operating systems (domU) running under the Xen hypervisor (dom0). This results in near 100% cpu usage on the guest, with the mcelog process blocking all other proccesses. This update adds a check to /etc/cron.hourly/mcelog.cron: if the check finds it is running on a para-virtualized guest, it exits, ensuring mcelog does not execute in such circumstances. (BZ#522827) All mcelog users should install this this new mcelog package, which adds the check to resolve this issue. -- Chad From alfredo.deluca at gmail.com Thu Apr 26 02:10:11 2012 From: alfredo.deluca at gmail.com (Alfredo De Luca) Date: Thu, 26 Apr 2012 12:10:11 +1000 Subject: throughput Message-ID: Hi all.

I'm curious about the actual problem you are either trying to solve or the symptoms of the problem you are trying to identify.
