Upon further investigation (using virt-manager/xm console), I found that they were hung at the “Checking for hardware changes” item in their boot process. This could be a CentOS/RHEL 5 issue, but I’m putting my money on xen. Michael Altfield Hi, I’m Michael Altfield. I write articles about opsec, privacy, and devops ➡ About Michael 
I’ve been playing around with SELinux at work recently. Not surprisingly, I was struggling to get SELINUXTYPE=strict to work properly. Unfortunately, all “google results for ‘enabling selinux strict’ would return were dead ends. People would enable selinux strict, kernel panic, and ‘fix’ it by disabling selinux. Well, a co-worker of mine *was* able to successfully enable selinux’s strict policy on RHEL5 (CentOS 5). He gave me this guide to post to the world for others to see how (thanks Mykola): Michael Altfield Hi, I’m Michael Altfield. I write articles about opsec, privacy, and devops ➡ About Michael Storage is getting so cheap these days. So cheap, in fact, that multi-terabyte home servers are now economically feasible. The emergence of cheap 1 terabye hard drives and ZFS perfectly compliment each other. Like others, I’ve embraced these two technologies to build myself a redundant, multi-TB disk array with 3x1TB drives running in a RAIDZ on OpenSolaris for about $300.

Red Hat If you want to be able to compile packages in red hat/centos, you can issue the following command: yum install make gcc gcc-c++ kernel-devel …or, if you don’t care about maintaining a small footprint, you can get *all* of the development packages (including X devs–eww): yum groupinstall "Development Tools"
Open Solaris If you want to be able to compile packages in open solaris, you can issue the following command: pkg install SUNWgcc Michael Altfield Hi, I’m Michael Altfield. I write articles about opsec, privacy, and devops ➡ About Michael tech.michaelaltfield.net/ Hello world! I just updated my whole server environment and, my, things are looking good. Anyway, I had to run through these steps a half dozen times, so I thought I would post it here for myself and (maybe even) others. Here’s the commands I ran to turn a clone of my base RHEL5 (CentOS 5.2) Xen image into another working virtual machine on my RHEL5 (CentoOS 5.2) Xen Host: Michael Altfield Hi, I’m Michael Altfield.

I recently reformatted my hard drive–switching from pure Gentoo to the Sabayon fork. Sabayon did for Gentoo what Ubuntu did for Debian. It’s generally a lot easier to use, but–unlike Ubuntu–it doesn’t sacrifice functionality for ease-of-use. Michael Altfield Hi, I’m Michael Altfield. I write articles about opsec, privacy, and devops ➡ About Michael To a degree, I still actively work on my high school soccer team’s website (which I created back in 2005). I started working on it on and off since summer 2008, and 71 hours of development later, I finally pushed my changes to the live server in January 2009. Michael Altfield Hi, I’m Michael Altfield. I write articles about opsec, privacy, and devops ➡ About Michael I went to send an email the other day and I was halted when I discovered that my key had expired. I can’t believe that I’ve been using GPG for 6 months, but the time had come to generate a new keypair. This post outlines the process to gererate a new keypair once your old keypair has expired.

Unlike Ubuntu upgrades, this process was farily painless except for one thing: my Zerina OpenVPN ‘plugin’ broke. Michael Altfield Hi, I’m Michael Altfield.
