I was shocked to see Robyn Bergeron’s email today about Seth Vidal’s passing.
Pairing virt-manager with KVM makes booting new VM’s pretty darned easy.
The confined user support in SELinux is handy for ensuring that users aren’t able to do something that they shouldn’t.
David Egts and Gunnar Hellekson were kind enough to invite me to participate in their Dave and Gunnar Show podcast during the 2013 Red Hat Summit.
The 2013 Red Hat Summit was my second one and I enjoyed it more than last year.
Most of my websites run on a pair of Supermicro servers that I purchased from Silicon Mechanics (and I can’t say enough good things about them and their servers).
It’s been a little while since I last posted about installing Xen on Fedora, so I figured that Fedora 19’s beta release was as good a time as any to write a new post.
I’ve converted one of my KVM hypervisors from CentOS 6 to Fedora 18 and now comes the task of migrating my virtual machines off of my single remaining CentOS 6 hypervisor.

I’m still quite pleased with my Samsung Galaxy SIII but there are some finicky Bluetooth issues with my car that I simply can’t figure out.
I was sitting at my desk yesterday when I saw a tweet from @LinuxFoundation:
Although GRUB 2 does give us some nice benefits, changing its configuration can be a bit of a challenge if you’re used to working with the original GRUB for many, many years.
LVM snapshots can be really handy when you’re trying to take a backup of a running virtual machine.
This problem came up in conversation earlier this week and I realized that I’d never written a post about it.

Anyone who has been a system administrator for even a short length of time has probably used traceroute at least once.

As promised in my earlier post entitled Kerberos for haters, I’ve assembled the simplest possible guide to get Kerberos up an running on two CentOS 5 servers.
Scientific Linux installations have a package called yum-autoupdate by default and the package contains two files:
I’ll be the first one to admit that Kerberos drives me a little insane.
I used to be one of those folks who would install Fedora, CentOS, Scientific Linux, or Red Hat and disable SELinux during the installation.
