SPARC Logical Domains: Alternate Service Domains Part 3

In Part One of this series we went through the initial configuration of our Logical Domain hypervisor, and took some time to explain the process of mapping out the PCI Root Complexes, so that we would be able to effectively split them between the primary and an alternate domain. In Part Two of this series we took the  information from Part One and split out […]

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, that this is not a cure-all, for example base firmware updates would still be interruptive, […]

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 other hypervisor solutions, it doesn’t require any complicated cluster setup, no management layer, so you […]

Solaris Virtualization: Using Logical Domains on Solaris 11 Part Three

In our previous articles we built the foundation of our Logical Domains environment, which then enabled us to create a Logical Domain in part two.  Now in the final article in this series we will be connecting to and performing the installation of the operating system. Solaris Virtualization: Using Logical Domains on Solaris 11 Part One Solaris Virtualization: Using Logical Domains on Solaris 11 Part […]

Solaris Virtualization: Using Logical Domains on Solaris 11 Part Two

In our previous article we went through the process of preparing a Solaris 11 for SPARC machine as a Logical Domain hypervisor.  Now that we have laid out our foundation we are ready to create some Logical Domains. Solaris Virtualization: Using Logical Domains on Solaris 11 Part One Create the Logical Domain Configure Devices We will need to add devices to our newly created domain.  […]

Solaris Virtualization: Using Logical Domains on Solaris 11 Part One

Solaris 11 for SPARC, as well as previous versions of Solaris, include a neat little technology called Logical Domains (which has been rebranded as Oracle VM for SPARC).  Logical Domains are implemented in the SPARC processor. This series is going to focus on the basic administration of a Logical Domains environment using the basic command line tools of the Solaris 11 Operating System.  In Part […]
