Hi all, After rebooting my CentOS 5.5 server, i have the following message: ================================== Red Hat nash version 5.1.19.6 starting EXT3-fs: unable to read superblock mount: error mounting /dev/root on /sysroot as ext3: invalid argument setuproot: moving /root failed: No such file or directory setuproot: error mounting /proc: No such file or directory setuproot: error mounting

I have a grub.conf (below) with pci=nomsi, also /proc/cmdline and dmesg | more do not show the pci=nomsi. How can this be? there are no strange characters after quiet and before pci=nomsi. It was edited with vi. What can I do to get this parameter in my kernel boot line. Jerry ----------------- default=0 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS

Hi, I have an issue with my XEN servers, in that when I do a yum upgrade, it upgrades the kernels, and then updates the grub.conf file to boot with the normal Linux kernel, and not the XEN kernel - and I tend to forget to update the grub.conf, until I reboot and see XEN isn't running. So, is it safe to remove the normal kernel & kernel-development, and only run the XEN kernel? This is

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

Many times when i boot my Xen machine i get a message saying something like "The greeter application has failed many times, using alternative greeter." From there on I can do everything OK as far as i can see. Sometimes when i boot the machine, it just randomly restarts halfway through the boot process. It has also been crashing alot lately when i try to run it 24/7. Any ideas? here

Hello all, I am sort of new to XEN and I have a dedicated server that is hosted for me. This server is an intel single quad 4 with 4 gig of ram. The OS is Centos 5 completely updated. I have installed XEN from the add and remove applet within Centos. Here is my grub.conf: default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-92.1.10.el5PAE)

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

Post a photo of the error message somewhere if you can?t describe it better than that. You might have to turn off rhgb mode to get a

Hi. I am trying to install xen 2.0.5 and am having problems getting the xen kernel to boot. It seems to come up, recognize the PCI bus info, the CPU, memory, and such, and then halts when it gets to trying to mount NFS. It then asks for a boot floppy. My guess is that it is not finding the / partition. The actual kernel panic string, I don''t have because the screen blanks so

This is irritating: I've got a server I just upgraded to 5.4, then rebooted, only to discover that it just *sits* there at the grub boot menu. I looked at grub.conf, and uncommented hiddenmenu (which should have been done long ago). It *still* sits there when I reboot. Any clues, folks? mark grub.conf: #boot=/dev/sda default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz

I've also had a few Xen systems grub entry issues. I'm not yet sure what triggers the events, but I do think there *may* be a correlation to the "/boot" part. I've found the Xen servers that have "/boot" before any of the the lines like "/boot/xen.gz" ended up missing complete grub entries. Not sure it's 100% true. Anyone else comment? Thanks PJ On

Hi All, After updating to the latest kernel, I get subject error at grub. I have no idea as to how to fix this. Booting of the previous kernel is fine. Could someone please help sort this out?

Hi. I used VMware Standalone converter 5.5 to convert a CentOS 5.3 machine from a Physical server to a Virtaul Machine on ESXi 5.1 . Thus far with every attempt to convert this machine I get a "Kernel panic" mount: could not find filesystem '/dev/root' setuproot: moving /dev failed: No such file or directory setuproot: error mounting /proc failed: No such file or directory

First let me say that I'm not a sysadmin, but am simply wearing that hat this week so please excuse my ignorance. I need to temporarily move some virtual servers from a CentOS-KVM platform to a CentOS-XEN platform while I do some upgrades to the CentOS box. I've created a local LV, and used DD and SCP to transfer the block device from the VKM machine to the XEN machine. For quite a

HI, We've started to see several issues with the Xen releases. Going back to basics I've used this guide https://wiki.centos.org/HowTos/Xen/Xen4QuickStart Once the install process is complete the grub.conf looks like this: default=0 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (3.18.21-17.el6.x86_64) root (hd0,0) kernel /boot/xen.gz

Hello Xen users, I tried to install Xen 3.1.0 on Scientific Linux (RHEL4), but this mission failed.. Hope you can help me by finding the reason for my problem. I downloaded the xen sources from http://bits.xensource.com/oss-xen/release/3.1.0/src.tgz/xen-3.1.0-src.tgz and compiled them by running "make" and "./install.sh". This seemed to work. After setting up grub like
