Problem compiling ogg on OpenBSD-2.7
Hi, I have downloaded the following files libao-0.6.0.tar.gz libogg-1.0beta4.tar.gz libvorbis-1.0beta4.tar.gz vorbis-tools-1.0beta4.tar.gz as said from the download section.

Issues while using kdb to debug Xen
Hi, I have been trying to debug Xen using kdb. However, I am unable to successfully boot dom0 after compiling and installing kdb. Software/hardware config: Base distribution - Debian Lenny (64-bit) on a Dell desktop (Optiplex 780) with a serial cable to another machine. Xen 4.0.1 (without kdb) works fine. Here are the steps I followed to set up Xen-unstable with kdb. 1. Cloned code from

Running Apache sites as separate users
I had a recent request to improve security on my web servers by having each website use a different user to run the hosting service. So example1.comhas it's own Apache instance running as apache1 and then example2.com has its own instance of Apache as apache2. Is this even possible or realistic? I understand the idea of how that would be secure, much like creating a virtual machine to

Using Samba to share Apache web root, securely
I'm setting up a shared web server running Apache. Each web root will belong to a department, which has a corresponding Active Directory group to give access. So far I've got samba working and such, but am having some trouble wrapping my head around the necessary permissions to make all this work, especially securely. So far I've found that both the POSIX and the ACL permissions

Sudo #includedir function ignored CentOS 6
I am unable to get the #includedir function to work with sudo. This works just fine on all my CentOS 5.6 servers, but on 6 it is being ignored. I have this line in the file /etc/sudoers.d/zabbix-puppet zabbix ALL=NOPASSWD: /var/lib/zabbix/bin/start_puppet However sudo still requires a password. If I put that same line into /etc/sudoers file , there is no password prompt. At the end of my

Excluding RAW disk from snapshot
I have an oVirt engine node that currently runs the system on a qcow2 based virtual disk, and an NFS export volume on RAW. I'd like to take a snapshot before a somewhat risky upgrade of oVirt and can't with the raw image attached. Looking at the documentation for the snapshot XML, I created this XML file for the snapshot <domainsnapshot> <name>20120802</name>

CentOS 6 and KVM woes
I have decided to migrate my latest KVM server to CentOS 6.0 and am beginning to get a little frustrated with some issues that worked perfectly in 5.6. Right now I've given up on getting virbr0 and NAT to work, but now I need networking bridging to work, but nothing seems to fix the issue. I have not had much experience with troubleshooting KVM so could really use some pointers on resolving

CentOS 6 DVD install "Unable to read group information from repositories"
Tried my first CentOS 6 install on a system currently running 5.6. My attempt was not an upgrade, but a full re-format. I have verified the checksums of the ISO and did the pre-install disk verify and everything checked out. However after the screen for setting up the bootloader I get the following error "Unable to read group information from repositories. This is a problem with the

Libvirt daemon usage question
I could use some help with clarification on the use of the libvirtd daemon with regards to managing remote KVM instances. Right now I have a CentOS 6 KVM server (libvirt-0.8.1), but would like to use some management applications that require higher version (0.8.8). First, is it possible to run the libvirtd daemon from within a VM, or does it require active kvm kernel module? Secondly, could a

SELinux triggered during Libvirt snapshots
I recently began getting periodic emails from SEalert that SELinux is preventing /usr/libexec/qemu-kvm "getattr" access from the directory I store all my virtual machines for KVM. All VMs are stored under /vmstore , which is it's own mount point, and every file and folder under /vmstore currently has the correct context that was set by doing the following: semanage fcontext -a -t

Upgrade from CentOS 5.x to 6.0
Great news about CentOS 6.0 being available, and I figured I'd ask the most obvious question, what can I expect when upgrading from CentOS 5.6 to 6.0? I have not had to go from one major version of CentOS to another so this is new territory for me. Is the processes just like an install except there's an "Upgrade" option? Does an upgrade do a "yum update" of

Hi T'm trying to convert XEN virtual machine image into raw. Source file is on NFS export and destination is also on nfs export. (both exports are mounted on migration servers RW access). I'm getting permission denied. I have RW access to both exports - I can create, delete objects on both exports from migration server. But when I copy img file onto migration server local filesystem,

Package: virt-goodies - partly solved
For CentOS KVM migrations use the virt-v2v package part of base.

CentOS 6.0 CR mdadm-3.2.2 breaks Intel BIOS RAID
I just upgraded my home KVM server to CentOS 6.0 CR to make use of the latest libvirt and now my RAID array with my VM storage is missing. It seems that the upgrade to mdadm-3.2.2 is the culprit. This is the output from mdadm when scanning that array, # mdadm --detail --scan ARRAY /dev/md0 metadata=imsm UUID=734f79cf:22200a5a:73be2b52:3388006b ARRAY /dev/md126 metadata=imsm

XML file format for snapshot-create
I've created a very basic snapshot XML file, to allow for a description of the snapshot. However when running the virsh command, it doesn't like the formatting. # virsh snapshot-create proxy_0 /vmstore/proxy_0/proxy_0_ss.xml error: XML description for failed to parse snapshot xml document is not well formed or invalid This are the XML file contents... # cat proxy_0_ss.xml

Submitting patches from upstream fixes/bugs
What is the preferred method for submitting patches from upstream projects ? I have two patches for libvirt-0.8.1.el6_0.6. One adds ESX 4.1 support to things like virt-v2v ( http://www.redhat.com/archives/libvir-list/2010-July/msg00480.html) and the second fixes the broken "virsh snapshot-create" ( https://bugzilla.redhat.com/show_bug.cgi?id=727709).
