  • Using KVM virtualization – Kernel Virtual Machine (KVM) virtualization has largely replaced Xen as the default open source mechanism for creating and supporting virtual machines (VMs) on most Linux systems. Though the motivation for this change is primarily build and support related rather than technical, the reality is that many enterprise IT groups that are interested in virtualization will need to learn the administrative command-and-control tools that KVM uses. Similarly, IT shops with an existing investment in Xen virtualization that are moving to KVM will probably want to convert existing VMs to the formats that KVM supports whenever possible, rather than having to re-create them.
  • Create Linux and Windows images for OpenStack private clouds – This article proposes a new way to construct Linux® and Windows® images for private clouds built with the OpenStack cloud operating system.

  • JQueryin | Switching Apache from Prefork to Worker MPM in RHEL / CentOS 5.x / Fedora 13 – I’m going to outline the process of switching from Apache’s default installation of MPM Prefork to that of MPM Worker. I will also be covering the proper installation of FastCGI (mod_fcgid) to further improve your server performance. This guide is ideally intended for individuals running on low-memory VPS servers as memory consumption will likely be far lower with the Worker MPM because it spawns threads as opposed to forking child processes. If you’re intentionally reading this article, you’re probably aware of the performance benefits gained.

  • ottimizzazioni (quasi) estreme – In fondo, perché far ricomprimere ad Apache lo stesso file centomila volte al giorno, se questo non cambia praticamente mai? Non sarebbe possibile comprimerlo “a priori” e poi istruire il server a fornire la giusta versione a seconda che il browser dell’utente supporti o meno il formato gzip? A quanto pare la risposta è si
  • Trouble-Maker – Being a system administrator is full of interesting challenges. We like this. However, some of these challenges can be problematic, if they cause service interrupts on production systems. Most system administrators have run into the situation where something is wrong, the server is down, and we don't know what is going on. This project attempts to help.<br />
    <br />
    There are a lot of tools out there to make the system administrator's life easier. However, no tool is a replacement for properly understanding the system and experience in troubleshooting unknown situations. This is where Trouble-Maker comes in. Unlike other projects, we do not attempt to solve problems — we cause them.

  • Keeping an eye on TSM volumes – […] I wrote a quick script which tells me when volumes in TSM (Tivoli Storage Manager) have access and/or media issues and shoots me off an email. The script does two things:<br />
    1) Checks for volumes which are NOT in the states READWRITE or OFFSITE.<br />
    2) Checks for volumes which have a read/write error count >0.<br />
    I’m sure that most people running TSM in their environment have some sort of daily reporting that gets sent out. If that’s the case, you can simply extract the SQL from the script and use it in your own reporting tools.<br />
