In the past I hacked around a problem with the order of starting (and with several bugs) a network stack combined of network bonding (teaming) + VLAN tagging, and then with network bridging (aka – Xen bridges). This kind of setup is very useful for introducing VLAN networks to guest VMs. This works well on…
I have encountered several methods of doing stateless RedHat Linux systems. Some of them are over-sophisticated, and it doesn’t work. Some of them are too old, and you either have to fix half the scripts, or give up (which I did, BTW), and after long period of attempts, I have found my simple-yet-working-well-enough solution. It…

I have created a GUI cables installer and configurator for L2TP on Linux. I have noticed that there is no GUI solution, so, after this has been brought up, I…
Working with RH Cluster quite a lot, I have decided to create an online store of customer agents/scripts. I have not, so far, invested the effort of making these agents accept settings from the cluster.conf file, but this might happen. Let the library be! Oracle DB script/agent: Although I discovered (a bit late) that RH…

But like any other software product, it has few flaws and issues which you should take under consideration – especially when you create custom “agents” – plugins to control (start/stop/status)…
Most documentation on the net is about how to run a cluster-in-a-box under Vmware. Very few seem to care about protecting Vmware guests under real RedHat cluster with a shared storage. This article is just about it. While I would not recommend using Vmware in such a setup, it has been the case, and that…
