CentOS 5 Server :: Xen Guest Won't Boot After Update / Solution For This?
Dec 21, 2009
I'm experiencing some rather severe problems after updating my Centos 5.4 system (Virtual Xen guest). What happens is that when the system boots it complains about missing .so files which prevents about 50% of the services installed from running.
I'm suspecting that it has something to do with selinux for two reasons: 1. The first services to go down complains about the security context of some files, and 2. selinux was kinda the reason I decided to update in the first place as it was disabled when it shouldn't be (enabled in system-config-securitylevel, disabled when running sestatus).
The whole boot-sequence ends with alot of "INIT: Id 'X' respawning too fast: disabled for 5 minutes"-messages (including all runlevels) before it goes stale, and I can do nothing.
The server in question had undergone very little tinkering from my part, pretty much none at all, the only services installed after installation was apache, mysql and webmin.
Details:
CentOS 5.4 is installed on both the host and guest.
The guest runs on an lvm-partition.
I have two other vm's(also CentOS) running just fine, altough I'm a bit weary of updating them .
Attached are some screenshots of the boot-process.
I hope some one here can share some insight on this problem. It's making me pretty nervous seeing that our whole network is run by CentOS-installations (not that I'm certain that CentOS is the culprit).

So I just installed Karmic onto my netbook that used to have Jaunty on it. As usual I did a system update after the clean install finish. In that update it included a kernal update to 2.6.31.19. As far as I know the update went fine.So when I restarted, after the usual bios screen, it just freezes. Some gibberish comes up and nothing happens. I did a hard reset. Then when bios came up again, I chose boot option, and then clicked to boot from my hard drive. GRUB came up (finally) and I chose the old kernal and it booted fine.
Just for good measure I tried booting from 2.6.31.19 and the same strange freezing thing that I mentioned in paragraph two happened.

Last I upgraded one of our cent 5 boxes which is running kvm with a mix of centos and windows VMs.After the update performance just tanked on the XP guest, but the others (including other windows VMs) are just fine.I checked with our good friend google and didn't really get any help there.We're hoping to NOT have to rebuild the XP guest, so I thought I'd check in here first.
This is CentOS release 5.5 (Final) with kernel
2.6.18-194.32.1.el5 #1 SMP (64bit)

So I ran the update manager to install the latest kernel. It goes fine and was sitting at the restart prompt. I was playing minecraft and the entire system locked up - couldn't restart X or anything. Hard restart and I get a multitude of errors mostly dealing with not being able to find things in /dev/... It gives me a command line but I'm lost as to where to go from here to repair my system

I just ran into a weird problem with a CentOS 5.5 64-bit server running VirtualBox 3.2.8 (I would run Vmware Server 2.0.2 if not for the well known fact that Vmware doesn't care about its Server line anymore and it doesn't run on CentOS > 5.3 without major splits). I currently have two guests in that VirtualBox setup, a CentOS 5.5 64-bit and a Fedora 13 64-bit. The CentOS 5.5 guest shows less memory available than configured. If, for example, I give the virtual machine 512MB of memory the guest OS only recognizes 380MB. If I give it 768MB it only recognizes 637MB, and so on. I don't have that problem on the Fedora guest - 1024MB configured, 1024MB available.

Let me start off with the usual: I'm a linux newbie but am doing pretty good so far with google by my side. I've come across a problem I cant seem to find an answer to:
I just got a CyberPower 685 AVR UPS. I Installed their power panel software and it works great in CentOS 5.4. When I reboot, the system hangs right after the "Red Hat Nash 5.6..... Starting" message. I've left it for 20 mins so far and it's still hanging. If I unplug the USB data/shutdown cable, within about 10 seconds it starts detecting hard drives and continues booting...
Ive even returned the UPS for another to see if it was bad, and it still is giving me problems.

I have a new public mail server running under Vmware Server 2.0 installed on Windows Server 2008. I'm not satisfy about performance, virtual machine has got 3gb of ram and 2 virtual cpu. Physical machine has got one intel xeon cpu 2.4ghz quad core, 8 gb of ram and 3 hdd 500gb raid5. I already set this option: Fit all virtual machine memory into reserved host RAM. How can I increase performance? Are there any kernel build for virtual installation?

I am new to virtual machines in general, and currently playing with the XEN-based VM in CentOS 5.5. Question: if neither virt-manager nor virsh (using "virsh edit <guest name>" and changing the name in the XML file) are designed to actually change a guest's name...then what is the recommended procedure for doing this?

I have the following strange thing with a RHEL4 installation. Since last week, the system did a reboot and now something is really fucked up. During boot we get the following messages (don't care about 'strange' typo's, my colleague typed it 'blind' from the screen)
Code:
The strange thing is that we never see a 'could not mount blabla' or similar messages. First we thought it was a failing kernel update by plesk, but even after manually updating the kernel with RHN RPM's, still the same message. Booting with rescue mode and then chroot the system works. After that we even can start things like plesk and so on.
We double checked things with another RHEL4 install, and at least two things were odd:
1: the working machine has /dev/dm-0 and /dev/dm-1, the broken one doesn't
2: some files on /dev didn't have group root, but 252
We tried to recreate the /dev/dm-X nodes with [vgmknodes -v], output:
Code:
A fdisk /dev/sda shows: /dev/sda2 XX XXX XXXXX Linux LVM (I removed the numbers because this line is from another machine, but rest was identical)
We have a copy of the boot partition so if one need more info please let me know.
grub.conf:

last part of init extracted from initrd-2.6.9-78.0.8.ELsmp.img:

I have 4 VMs on a Linux host, call them A, B, C, D running on Z. I really don't care when A and B come up, but I would like to make sure that D comes up before C.I believe that in VMWare 2.x it's possible to change the boot order. Is this possible in 1.x as well? Is this done in /etc/vmware/vm-list? I see that there are a number of VMs listed there, including some that have long since been deleted.

Problems with xen 3.1.2 creating and installing domU CentOS 5.5 I am trying to do a virt-install --prompt --paravirt, and the install error out while trying to download install RPMs. I have googled for xen centos virt-install and various permutations. I have found similar howtos for 5.4 and 5.3, but they resulted in the same outcome. I did find several posts with similar issues, but no solution was posted.[URL]..

After installing and running for 4 weeks Ubuntu 9.10 without any modification the update window pops-up to inform me of new safety
updates as it did before.
While trying to install the new updates the same window appears without
making any updates.
Regardless how many retries the result is the, no update.
However when I use apt-get install update, it works.
After the update and after restart when using the update manager again
the same updates appear to be ready for update, and the subsequent attempt
to install is unsuccessful.

I am unable to boot with kernel 2.6.35.13-92.fc14.x86_64 which was installed while applying software updates. It hangs with the last message issued "Registering binary handler for Windows Applications". Searching led to it being related to a problem with the nvidia drivers. I followed the directions in several posts - delete /etc/X11/xorg.conf, reboot, run nvidia-xconfig, reboot and all is fine, but not in my case. The first reboot works but the screen is wrong. There is a 1 inch wide black border around the presentation window. If I then do the nvidia-xconfig and reboot, i am back to where I was before - boot hangs after issuing "Registering...". If I boot to the last good kernel, everything works fine. This happened to me once before and I was able to fix it by rebuilding the nvidia kernel (I think that was what I had to do), but I can't find out how to do that. I have akmod and kmod installed which are supposed to take care of this problem. I booted to kernel 13-92 recovery mode, deleted the xorg.conf file and ran nvidia-xconfig from there. Still fails. I don't know what to list here, but I will do my best to supply whatever is necessary.

I have installed Centos and after few days I used it as a web server, database server (MySQL) and have some very important for me applications installed.
Today - I have read about "yum -update" function and I (a dummy one...) tried it. After some minutes the process was finished. But unfortunatelly - my server did not boot any more.
As startup options I have:
CentOS (2.6.18-164.6.1.el5)
CentOS (2.6.18.-164.6.1.el5PAE)
CentOS (2.6.18-128.2.1.el5PAE)
CentOS (2.6.18-128.2.1.el5)
CentOS (2.6.18-128.1.14.el5)
CentOS (2.6.18-92.el5)
I'm not sure what are these options. Anyway - I have tried to choose every one and the result is aways the same : red Hat Nash version 5.1.19.6 starting
Then starts the clock [ok],
Then starts the "udev" [ok]
And then My screen goes to suspend mode, with the text "no signal".
The most important thing is to backup the data from the hard disk. Do I have any chance to repair this installation ?

I had a Centos 5.5 system working great...and then due to crazy curiosity, installed the kernel update. Did this through the graphical interface, uncheck all update other than kernel. It downloaded, installed fine..After reboot now all I get is GRUB_ and then nothing else! I waited 3-4 minutes and had to shut down system. Have been googling around but thought I will post it here as well..When I boot with Win7 and use Ext2fsd to check, the boot folder is empty. Not sure if this is because ext2fsd does not read boot folder or it got wiped out by the yum upgrade process.

I have recently run an update and now we are unable to boot the newer kernel. We get stuck as below;
Memory for crash kernel (0x0 to 0x0) notwithin permissible range
Red Hat nash version 5.1.19.6 starting
Unable to access resume device (/dev/VolGroup00/LogVol06)
[Code]...
The kernel version we were at was 2.6.18-194.el5 and the update move us to 2.6.18-194.17.1.el5. I've done some googleing but I'm unable to work out exactly what I need to do. I'm guessing the new kernal is missing a module?

I have installed Centos 5.6 on a fresh VPS. After install I ran yum update command. After update was finished I noticed a message saying "Your system kernel may have been updated. Current kernel (2.6.18-238.e15) has been changed to : 2.6.18-238.12.1.e15)". When I reboot, I see two boot option in GRUB. one is Centos 5.6 (2.6.18-238.12.1.e15) Default and other is Centos 5.6 (2.6.18-238.e15). When Centos boots from default, it fails with fatal error. But when I boot with other option, the system boots as normal.
I need to know how to resolve this situation. Why yum update results in Kernel update and 2nd option in GRUB boot loader. and why Centos refuses to boot with update Kernel.

i want to know two thinsg about yum update
1) does it overwrite existing configuration files that is will i need to reconfigure every service after running yum update
2) If somebody pushes the reset button or electricity to the system is reset while yum update is running what will happen i think there can be two stages to that
a) if it is still downloading while the electricity to system is reset
b) it is installing while electricity to system is reset
