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
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.
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
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
In part 1 of the series I covered basic machine set up and preparation. In this second part of the series about setting up KVM on Ubuntu 14.04 I cover setting up the network. Setting up the network can seem quite daunting but a basic KVM install doesn’t actually require much network set up.
I’ve been running my own servers for many years now but recently I’ve started to get the feeling that I could be doing a better job of it. I’ve played with virutalization a little both on the desktop and on real servers (I run a small VMware set up for work) but I’ve never translated that to a home virtualization system. I want to start virtualizing at home because I want to separate my personal servers and software development from my work software development. I could run another physical server but the machine that I have a the moment is quite lightly loaded so there’s really no good reason to run another physical. My virtualization of choice is KVM on Ubuntu and that is what this seven article series is about.Continue reading
I have a number of Ubuntu 14.04 virtual machines installed under VirtualBox running on Windows 8.1 and occasionally I find it useful to have the VirtualBox additions installed. Unfortunately for me the documented process doesn’t seem to work. Whenever I mount the ISO image using Devices –> Insert Guest Additions CD Image… I find that /media/cdrom is empty whereas you would expect to find the install script. This article explains how I install the additions.Continue reading
