SPARC Logical Domains: Alternate Service Domains Part 1
In this series we will be going over configuring alternate I/O and Service domains, with the goal of increasing the serviceability the SPARC T-Series servers without impacting other domains on the hypervisor. Essentially enabling rolling maintenance without having to rely on live migration or downtime. It is important to note,…
SPARC Logical Domains: Live Migration
One of the ways that we are able to accomplish regularly scheduled maintenance is by utilizing Live Migration, with this we can migrate workloads from one physical machine to another without having service interruption. The way that it is done with Logical Domains is much more flexible than with most…
Linux KVM: Bridging a Bond on CentOS 6.5
Today we are going to hop back into the KVM fray, and take a look at using CentOS as a hypervisor., and configuring very resilient network connections to support our guests. Of course these instructions should be valid on Red Hat Linux and Oracle Linux as well, though there is…
