I’m in the process of writing some capistrano recipes to make deploying to Amazon’s Elastic Compute Cloud (ec2) easier. Since I’m making this project available for general consumption, I wanted a way to make it easy for someone to try it out without having to check something into source control. (more…)
I setup a xen based system for our production environment at work. I’m using LVM throughout for all the benefits it provides (resizing, snapshot backups, etc). Each domU gets its own logical volume on dom0’s volume group. This logical volume actually looks like an entire physical disk to the domU, and the domU then further partitions it into a boot partition and a nested LVM partition (swap + root fs). Aren’t the layers of unix file abstractions a thing of beauty to behold? 
In retrospect I probably should have mapped LVM logical volumes direct from dom0 as partitions in domU rather than having domU add the extra LVM layer on top - though reading around shows that this _may_ not be supported in the future, so… (more…)
