I have successfully set up a very nice kickstart install with the i386 version of CentOS 4.3 and it works great. I am using a custom kickstart script and the kernel and initrd from disc1/images. But when I try to duplicate this for a 64 bit setup (changing paths in my tftp server, ks.cfg, etc to point to the 64 bit stuff) it successfully tftp's everything just as it should (tethereal

When using buildinstall and CentOS 5.2 to create my own CD minus a bunch of unneeded RPM's and plus a few of my custom RPM's I find that the install CD that gets build does not install an initrd which renders the system unbootable. I also notice that when I run buildinstall with the -debug option it says: unpacking

Hi, I''m a long ext3 user (rpmfind.net). I propagated ext3 on some of our server box (W3C webservers are ext3 based too now). I might be tempted of testing out your kernel RPMs but unavailability or the source RPM and the SMP version are definite showstoppers. Please provide them. In the meantime I will stick to my own set of kernel ext3 RPMs at ftp://rpmfind.net/pub/veillard/ext3/

I am trying to get a CentOS 6.3 serial console to work with IPMI SOL. I think I have everything working but maybe the wrong baud rate on the getty: $ ipmitool -I lanplus -U root -H 10.0.0.14 sol activate Password: [SOL Session operational. Use ~? for help] ?????????? 10.0.0.14 is the DRAC IP address of the CentOS 6.3 box. It accepts the password and connects me to the console but then when I

I have a consulting client who has a Linux based storage appliance which is based on Fedora Core 2. I'll pause here while you laugh... They need to upgrade to something more easily supported and CentOS is the chosen distro. They have the source RPM's for their old system stored in CVS and have a very weird/complicated build system to turn it all into an iso which I am still figuring

Greetings, Xen developers! I have been using AoE with Xen to great effect and I am very pleased with how the whole system has worked out. The two technologies really complement each other. I consider it the ultimate setup. Aside from the network switch (eventually to be remedied) my serving infrastructure has zero single points of failure. However, this virtualization paradise has a flaw:

I would like to checkpoint some of my calculations in R, specifically those using optim. As far as I can tell, R doesn't have this facility, and there seems to have been little discussion of it. checkpointing is saving enough of the current state so that work can resume where things were left off if, to take my own example, the system crashes after 8 days of calculation. My thought is that

I keep getting an error when I try to attach a device in the libvirt api through python The python code is: conn=libvirt.open('qemu:///system') dom = conn.lookupByName("fedoratest") if dom.info()[0]==1: dom.attachDevice('net.xml') And I keep getting: "libvirtError: XML description not well formed or invalid The xml is a simple network

Hello all! I am trying to make a stripped down CentOS 5.2 distro which will all fit on a single CD containing just the base and a few other packages I need. I run buildinstall like so: sudo /usr/lib/anaconda-runtime/buildinstall --debug --version 5 --product CentOS --comps /var/www/html/centos/5.2/os/x86_64/repodata/comps.xml --release My-CentOS-5.2 --prodpath CentOS

Hi folks, I have set up a cluster on CentOS 5.2 using /etc/cluster/cluster.conf - and it works fine. It's only purpose is to switch a virtual IP between two routers. Now the service is running, I can ping the virtual IP from outside - but this virtual IP is not bound to any interface. How does this work? Can I force the cluster to bind it to a certain interface? I need this because the

I have been using Xen on a daily basis on a production (but not critical) machine for a number of months now. It''s looking really good. One thing that I have not yet seen anyone mention as a feature that I would really like to see is the ability to overcommit memory. I have 2G of RAM in my machine. I would like to give a developer his own virtual domain to sandbox his application

Hi! I know this is a little bit offtopic, but i couldn't think of any other place where i can get uninfluenced first hand information on these controllers :) I've read about and experienced data loss/system lockup with older 3ware controllers, but the 3ware Escalade 7xxx (i'm especially interested in the 7850) sounds too good to ignore it (8 channels, 8 drives, raid 0/1/5/10,

I've not seen this asked since I've been on the list; but was wondering... I'm currently sticking to the 2.2 line and have no plans to move to 2.4 right now. Is there any attempt to back port some of the changes in the newer 2.4 line back into 2.2? ext-0.0.7a.tar.gz has been stable thus far, but it's getting kind of old. NEM

Hi all, I'm using libvirt java binding (libvirt-java-0.4.6) I'd like to know if the Domain class offers an API to query volumes attached to a particular domain or should I parse the XML domain description?

Has support for creating or using lxc containers on remote machines been added to libvirt yet? https://help.ubuntu.com/12.04/serverguide/lxc.html says "Libvirt is a powerful hypervisor management solution with which you can administer Qemu, Xen and LXC virtual machines, both locally and remote." so I assume it's been done and I'm just having trouble seeing it... otoh, I hear

Hi, IIR/UC there have been a couple of discussions lately about possible evolution of libvirt's network management features to eventually support more kinds of virtual networking technologies like Openvswitch, VDE,... Could a kind and informed soul keep us on touch with progress in the field ? Thank you very much in advance PS: I wish this will be available before/for 1.0 release...

Are there any recommendations as to how often a new connection should be made versus reused? Right now we create a new connection *every time* we hit libvirt for something. We can easily change this so that a single connection is made for a series of libvirt calls, or even so that a single connection is used for the lifetime of the running application. What are the issues to consider when making

Hi, I'm revisiting my libVirt install for opensolaris. I downloaded libvirt 0.8.0.. This is a bit embarassing, but I forgot how to build libVirt on opensolaris. (It's been a while) I'm currently stuck with the configure script failing to find linux kernel headers. Error: "configure: error: You must install kernel-headers in order to compile libvirt" Can anyone post the

Hello Is there an easy way to get supported feature (API) list in each driver? The function would be to return a list which describes which APIs are supported and which APIs are not. Thanks in advance ozaki-r

Hello. I'm using debian squeeze with libvirt and kvm and I need to load a newer version of seabios into qemu. I'd like to do it without overwriting seabios in the debian package because that might be overwritten on the next update. I hopend that the <loader> directive in the config would work but it doesn't. thanks for any ideas. mk
