Hello. We have a number of Xen 3.4.2. boxes which have constant iowaits at around 10% with spikes up to 100% when accessing data over NFS. We have been unable to nail down the issue. Any advice?

This error is not 100% reproducible. However, kernel panic has been occurred many times for last two months. It usually happens when multi VMs (in our case, 14 VMs) are booting together. After we made three big changes to gain more availibility, it began to happen. Changes are : 1. Use *NAS* as vm storage for migration from local disk 2. Use *two bondings* for switch HA (with 4 nics) from

I recently updated to OpenOffice 3.2 and I noticed that it, and the latest Evolution, seem to be incredibly slow for some operations. E.g., in OO, about half the time when I'm editing something, it takes anywhere from 10-30 seconds for OO to respond to a click on one of the icons or menu items, and Evo is taking forever to format messages. During these times the gnome-system-monitor icon on

Hello all: I was getting a reproducible crash during an update of a xen system. The problem went away after I set SELinux to permissive, but the fact that it crashed was alarming (first one on a non-dev system that I've had in over a year). I attempted the update earlier but it crashed at the same point after attempting to update selinux. After verifying hardware (all clean) I ran it again

I'm migrating my son's Dell laptop from Vista to CentOS 5.3. He came back from each of his first two years of college loaded with virii and trojans. This year he said "Dad, can you give me Linux?" 5.3 went onto the laptop easily and after doing some research, I applied the guidance for getting multimedia working and got the nvidia driver loaded. That works great. Last

Everyone, about 4 years ago, I tried to install CentOS 6 on a Supermicro server with SCSI drives using a LSI raid system. I could never figure out or find a way to make the installation disc of Centos 6 identify the SCSI drives. The installation disc for Centos 5 identified the SCSI drives without a problem. I finally gave up on Centos 6 and installed Centos 5 and the system has worked very

Hello, I'm having a problem, I've seen other people with the same problem, but with USB. Some people solved this with the pciback.permissive option, but in my case it's ignored. I'm using CentOS 5.2 - 2.6.18-92.1.10.el5.centos.plusxen The error return from the console starting the domU is below. I've tried swiotlb=force, pciback.permissive like I said. My configs are:

I have not installed the madwifi specific kernel stuff (kdml and hal-kdml) from atrpms. I have installed with wpa rpms. And my Atheros card is working with almost no work on my part (other than runing wpa_supplicant as a deamon). Nice!
