Background In my ever evolving lab, it came time to integrate Red Hat Enterprise Linux (RHEV) with Identity, Policy, Audit (IPA).There were a few caveats and searching Google didn’t help, so hopefully this article can save you some time. Integrating the two was fairly straitforward. The biggest challenge was finding a quick and easy way

Background This weekend I decided to upgrade my home network with a Cisco WRVS4400N wireless router. Like a typical router it can provide standard wireless services WPA2, DHCP, etc, but the this model also provides support for four distinct VLANs and four distinct SSIDs. This has allowed me to create separate networks for work, play,
Background Recently, I had the chance to work on a couple of projects that took me into the cloud. The first project had me setting up Eucalyptus on KVM. The second had me building out an infrastructure in Rackspace Cloud Servers. This has given me some hands on insight into the problems that are facing

Background In my original post KVM Virtualization 101 and my second post KVM Virtualization 102, I explained some basic commands that are necessary to get on using KVM and some features for tuning KVM. In this article I move on to some of the more advanced problems when converting existing Linux machines from a
Background In my original post KVM Virtualization 101 I explained some basic commands that are necessary to get on using KVM. In this article I move on to some slightly more obscure topics in using KVM. Routine Operations CPU Type When you are operating in a KVM virtual machine the processor will report
Background For those of you who are familiar with virtualization, KVM is a hypervisor which is built into the Linux Kernel. This allows a Linux desktop or server to simulate multiple pieces of hardware, which can then have different operating systems installed. KVM uses the QEMU virtual machine format. QEMU may be familiar to those
Background Recently, I started a project at (www.eyemg.com) to migrate from VMWare to KVM. Our standard server deployment is based on RHEL5 running on HP DL380 hardware. Given our hardware/software deployment, it made sense to align ourselves with Red Hat’s offering of KVM. We are able to achieve feature parity with VMware server while adding
