CentOS 5 :: Xen Vm 'POST' And Error Messages - Guest Not Running
Jul 31, 2009
I'm running xen as installed from the CentOS Virtualization Suite and I'm having some problems. One of my VMs powers off immediately after an error during 'POST'. Is there a way to stop it from immediately powering off so I can see the error? And there's also at least one error message that appears for a split second after the vm craps out, before the gui console reports 'Guest not running'.
I put a script into the post installation of kickstart and the log showed that the yum that is started in the script had to wait for yum to finish. I understand I can (and will) put this package in the packages section, but isn't it bad that yum is still finishing up when the post installation is initialized? Has anyone else noticed this?
I'm trying to install the Guest Additions for a VM running a guest Lucid Lynx Server. The problem I'm encountering is this: The vboxadd-install.log for vbox says it "couldn't find the sources of your current Linux kernel" and to "Specify KERN_DIR=<directory> and run Make again."
I can't post messages, I think something is wring with my internet.Anyway, I'm gonna copy paste what I've been trying to say...I just bought the TP-LINK Model No. TL-WN821N. It's an atheros. And I was wondering where can I find the drivers for Linux. It only includes drivers for Windows.
I don't have much experience with networks,I found this website,

I got stuck in the patch section, I don't know what they are trying to say. They are using
I have CentOS 5.5 and try to create KVM virtual machine with CentOS 5.5 as a guest. But when I exec command: virt-install --connect qemu:///system --name test --ram 1024 --file=/var/lib/libvirt/images/test.img --file-size=10 --vnc --cdrom=/var/lib/libvirt/images/CentOS-5.5-x86_64-bin-DVD-1of2.iso --vncport=10000 --accelerate --os-type=linux --nonsparse --livecd --hvm
I think what i need to do is update the certifcate for the apache2, but I'm not sure how to do this, where to put it, and then which of the thousand apache config lines needs to be changed
when a remove a user from the system using the domain userdel guest the user gets removed but the /home/guest doesn't get removed so i remove it by command rm -rf /home/guest then i recreate the user by giving in the command useradd guest now it gives the error mailbox file already exists what does it mean when it says so though this command creates the user.
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]..

I dont know how to put this that somobody would understand my problem but here we go. I have problem like said in title.I am unable to upgrade my kernel. Sunaptics says that I have 2.6.35-28 installed. I tried to reinstall 2.6.35-28 via synaptics but it gives me error.
Thats what uname -a says:
pekka@pekka-laptop:~$ uname -a Linux pekka-laptop 2.6.35-25-generic #44-Ubuntu SMP Fri Jan 21 17:40:48 UTC 2011 i686 GNU/Linux
Tried to install 2.6.35-27 via terminal thats what I get:
Code: pekka@pekka-laptop:~$ sudo apt-get install linux-image-2.6.35-27 [sudo] password for pekka: Reading package lists... Done Building dependency tree code....

I read in documentation that the recommended kernel line settings for 64-bit Red Hat Enterprise Linux 5 running as a VMware guest are:
divider=10 notsc iommu=soft elevator=noop
But for single instance databases with dedicated storage the deadline scheduler is recommended. The deadline scheduler reorders I/O to optimized disk heads movement and caps maximum latency per request to prevent resource starvation for I/O intensive processes. I have an Oracle instance on RHEL5 running as a VMware(ESX) guest with dedicated storage. What scheduler is better in my case?
I installed mysqld with yum then yum quit working with this error:http://yum.baseurl.org/ticket/70 when mysqld is stopped yum works again. what does a running instance of mysqld have in common with a python yum package manager?
I have tried to install debian 5.0 and 4.0 without any luck. I have both tried virt-manager and virt-install with both debian-501-i386-netinst.iso, and full dvd. I't always gives me the same error:Starting install.Could not find an installable distribution at '/xen/debian-501-i386-netinst.iso'
After I login to KDE I see an error dialog saying,"ESC is already running, but is not responding. To open a new windows, you must first close the existing ESC process, or restart your system."
What is ESC and what can I do to stop this error dialog from popping up right after I login?
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.
We had an old Windows XP server running a Filemaker database on a 2.6 GHz Intel CPU, but that server died. It's been replaced by a box with two 2.4 GHz Xeon CPUs and 5 GB of RAM that's running Ubuntu 11.04 natively, and Windows is running as a VirtualBox guest. 2GB of RAM has been dedicated to the Windows guest.Of course, these old Xeon CPUs don't have the VT-x extensions, so I wouldn't expect to be able to add CPUs to the VirtualBox guest, but the Filemaker database is running at least 2-3x slower than it did on the old server. I would expect that utilizing one 2.4GHz CPU out of four available shouldn't result in such an astounding difference.
I would also like to be able to continue using this setup, since it would also mean we'd be able to remove our Linux server from the rack, which is running on even slower hardware (not that the system requirements are high for its job though).So my question is: Why is this so slow? Is there anything I can do to change the situation? Or should I just give up now and find more suitable hardware?I understand that the "new" machine should be about 1% slower in theory, so please don't tell me this "should" be fine. I need more concrete answers (as in, "I've tried this before and you should do X") since in the real world, it appears to be about 50% slower. I'm about to blame "virtual" CPUs to multithreading on single core processors, and possibly the difference in CPU architecture between Xeon and Pentium 4 CPUs.
I tried adding myself to the group vboxusers but it did not help.
I then read that the reason that i don't have any sub capability when i'm running XP as guest OS using VirtualBox is that I have a open source version of the program.
So I uninstalled the one I got through software center and downloaded and installed one from VirtualBox website. It installs but does not tell me where to find it in the menu so I don't know how to launch the program. It also doesn't show up as an "installed software" when I search for it in software center.
When I did update a few minutes back, it showed me the following messages

[code]...
I've not changed contents of any of these. Then why does it show me this messages? I did install akmod for my Nvidia graphics card for which I followed the steps mentioned for nouveau.
I'm running Ubuntu 9.10. I tried a solution for a wifi problem (wasn't always connecting) and now when I reboot I get "Ubuntu is running in low graphics mode" along with a bunch of EE messages. When I click OK it gives me "Run Ubuntu in low-graphics mode for just one session." Which gets me back to the desktop.
For some reason, when using this kickstart file the commands in the post section chroot is not executed. I used the ksvalidator to check the syntax and its correct.
Code: # Kickstart file. install cdrom key --skip lang en_US.UTF-8
I've got a Shorewall (Shoreline?) firewall up and running, but it's logging to /var/log/messages. I'd much rather have it logging to another location e.g. /var/log/firewall but can't find (a clear enough) explanation on how to do this. Apparently, it varies greatly depending on the distro, the kernel, and the version of Shorewall that is running. You'd think it would be something as simple as setting a path in a config file, but apparently not. I'm running a stock Lenny kernel on the firewall machine. It comes with version 4.0.15 of Shorewall.
do anyone know a quick way to inhibit/hide GTK warning, info and debugging messages when running GTK+/Gnome applications from terminal?I means those boring messages like "Gtk-WARNING blablabla..." and similar ones.
I've just installed clean copies of both VirtualBox v4.0.8 and Fedora 15. Now I have followed the instructions here : [url] to install the latest VBox guest additions.
Each time I try I get the following message:
The headers for the current running kernel were not found. If the following module compilation fails then this could be the reason. The missing package can be installed with yum install kernel-devel-2.6.38.8-32.fc15.i686.PAE.
However, if I run that command I am told there is no such package available. The guest addition installer continues seemingly OK, but after a restart they are not loaded.
I've just moved to Fedora from Ubuntu due to major issues with its new version.
I just got Ubuntu to install, which is great. However, during the part of the installation that involved setting up software, something went wrong. I used the alternate installer and toward the end of that step, it told me the step failed. I simply skipped the step because of this. The result: I've got Ubuntu going, but it's only the command line. I need some help getting GNOME installed from here. I searched and saw people saying to use sudo apt-get install ubuntu-desktop, but that just fills my screen with messages about missing files.
I want to design a kickstart file that creates an unattended installation (I've passed that part). After it installs, I want it to automatically read the device's MAC address and change the hostname to match the MAC address with the separators removed. (For example if the MAC address is 01-02-03-04-05-06, the prompt after login should read "root@010203040506")
I know this is entered in the "%post" section of the kickstart file, and I know I'm supposed to use the "cut" and "sed" commands, but I have no idea what I'm doing or how to do it. script so I can copy/paste it into my kickstart file?
