When I set up my QEMU virtual machine system I made a couple of mistakes. As I was running on a host that had very limited resources I made the virtual machines as small as I possibly could and that has come back to bite me at bit. The two problems I seem to constantly suffer from are running out space on the boot partition and, on one machine, running out of inodes.Continue reading

No Space on the boot Partition
When I installed my Ubuntu Linux virtual machines I just let the installer do whatever it felt was right in terms of disk partitioning. In hindsight that was probably a mistake because it gave me a separate 256Mb boot partition. While this partition is large enough to store several kernels I do find myself running out of space about twice a year if I keep the servers up to date.
Year of the Linux Desktop?
I just read this article over on betanews (not I site I’d ever seen before) stating that Linux was dead on the desktop because of Windows 10.Continue reading
Ubuntu Install – GRUB on the USB
It seems like only yesterday that I was installing Red Hat from floppy disks. Fortunately things have moved on a bit and now I generally install Ubuntu from a USB stick. The other day though I ran into a new problem. At the end of the process the installer asks if you’d like to install GRUB, I answered yes and unfortunately it proceeded to place GRUB on the USB install media.Continue reading
Simpler KVM Network Configuration
In the series of articles I wrote discussing the installation of KVM on Ubuntu I spent articles 2 and 3 discussing the network set up but it occurred to me that it was actually an unnecessarily difficult set up and so in this article I’ll discuss a simpler KVM network configuration set up.Continue reading
KVM Migration Problems
I recently experienced some KVM migration problems while moving virtual machines from my development laptop to my server. The laptop has a Core i7 processor but the server is running a Core i5 and, as you might expect, they have different features available. In this article I’ll explain what I did to fix my KVM migration problems.Continue reading
SonarQube with Jenkins Configuration
Configuring SonarQube with Jenkins while running Maven builds sounds like it should be a breeze but, I at least, found myself scratching my head wondering how to make it work. I’d got SonarQube installed and running and I had Artifactory installed and ready to go. Jenkins was running builds fine but getting SonarQube with Jenkins working was proving a little more difficult.Continue reading
SonarQube on Ubuntu 14.04
SonarQube (previously just Sonar) is an open source code quality tool. In this short series of articles I’ll be installing and configuring SonarQube on Ubuntu 14.04. Installing SonarQube on Ubuntu is just part of a wider continuous integration (CI) server build that I’ve been performing. Previous articles include installing Artifactory and Java 8.Continue reading
Migrating from Nexus to Artifactory
I thought migrating from Nexus to Artifactory would be a seriously painful process but it actually turned out to be quite simple. My biggest concern was maintaining my release history as it would be impractical to try and move hundreds artefacts by hand. The article below describes the process I used.Continue reading
Java 8 on Ubuntu 14.04
Getting Java 8 on Ubuntu 14.04 is a topic that is very hotly debated (1, 2, 3, etc, etc) but it looks like this important piece of software won’t officially make it into Ubuntu 14.04 in any time frame that is useful – I’m writing this May 2015, OpenJDK 8 was released March 2014 and it doesn’t look any closer to being included now than it did then.Continue reading
