similar to: UP vs SMP kernel ?

I''ve spent the past while researching this but I''m just not finding a solution. I''ve been trying to get my xen kernel booting on a pretty much stock CentOS 4.4 installation. I installed Xen from src rpm and installed all the requisite software and I''m sure it''s with the ram disk but I can''t figure out how to resolve this. With a stock kernel

I've been going along not noticing things happening right under my nose. so imagine my surprise when I discovered last night that my Centos 5 box has installed multiple new kernels over the last few months, as updates come out, and IT IS NOT BOOTING THE NEWST ONE. grub.conf says to boot kernel 0, and 0 is the newest one. but the one it actually boots is 6 or 8 down the list (clearly I've

Hello..I am not very proficient in Linux kernel stuffs although I know my basics. I have a question and all suggestions/solutions will be highly appreciated... I got to know that RHEL 5 has inbuilt Xen Support...So I tried to install a RHEL 5.0 Server on my P4 machine. On top of it I tried to install Xen specific RPMs and some other RPMs needed by Xen. The additinal RPMs added after base

Hello Xen Users, I am facing a problem getting my installation of XEN boot up on a Red Hat Linux Guest OS. What''s happening is that the grub loader tries to install Xen but after a while it crashes and starts rebooting recursively. I have tried both the entries listed below. I am using the following entries in the grub.conf file: title Xen-bhatia 3.0 / XenLinux-bhatia 2.6.16

Hi all, Recently I build XEN 4.1 (from the xen.org) on centIOS 5.5 (kernel 2.6.38.4). After changing the grub file and rebooting the machine, I am continuously getting out of memory error.

Could someone tell me what could be causing this failure on my system and a way to get around/fix it? Your help is very much appreciated. I'd just finished running lvm lvextend.

I'm playing with software RAID and LVM in some virtual machines and I've run into an issue that I can't find a good answer to in the docs. I have the following RAID setup: md0: sda1 and sdb1, RAID 1. This is /boot md1: sda2 and sdb2, RAID 1. This is a PV for LVM. VolGroup00, this is the volume group and md1 is the only PV in it. LogVol00 is swap LogVol01 is / LogVol02 is /home

Hi all, I compiled and installed Xen 3.2 source on FC8. Compilation and installation completed with no errors. However when I try to load Xen I get an error: Kernel panic - Attempted to kill init !!! This is my grub configuration: # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means

I have a degraded raid array (originally raid-10, now only two drives) that contains an LVM volume. I can see in the appended text that the Xen domains are there but I don't see how to mount them. No doubt this is just ignorance on my part but I wonder if anyone would care to direct me? I want to be able to retrieve dom-0 and one of the dom-Us to do data recovery, the others are of

Hello, I FINALLY got Xen working with VT-d. I compiled Xen-unstable (3.3) from Mercurial on CentOS 5.2, but compiled my own kernel-xen from the latest CentOS SRPM. (Made sure pciback was built-in and not a module, as the stock kernel-xen has it as a module.) I''m probably going to write a how-to soon, so stay tuned! I have a JMicron SATA/PATA PCI Express controller with a DQ35JO

Hello, We have default xen 3.1.2 on centOS 5.5. We now want to upgrade xen 3.1.2 to xen 4.0.1 while using the existing dom0 kernel (2.6.18).

I have a server running Centos 4.7 32bit. Will moving from 4Gig of RAM to 8Gig do any good? Since its 32bit I assume it will only be able to address the first 4Gig not? When I installed CentOS I did not do anything special to enable using more then 4Gig if thats required. Exim, spamassassin and Clamd seem to be the biggest load on this machine. My biggest bottle neck is disk I/O anyway. Wish

I have a plain vanilla Centos source (not 100% sure where we got it from), but I can't seem to get a build that installs correctly. I tried the method described at http://wiki.centos.org/HowTos/Custom_Kernel, but rpm doesn't like the output file, and even if I install it with -F, nothing seems to happen - no new kernel, now initrd, nothing. When I tried following the directions in the
