SPARC Logical Domains: Alternate Service Domains Part 3

Wed, 17 Dec 2014 00:00:00 +0000

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 our PCI Root Complexes and we configured and installed an alternate domain. We were also able to reboot the primary domain without impacting the operation of the alternate domain.

In Part Two (this article) we are going to take that information and split out our PCI Root Complexes and configure and install an alternate domain. At the end of this article you will be able to reboot the primary domain without impacting the operation of the alternate domain.

SPARC Logical Domains: Alternate Service Domains Part 1

Mon, 15 Dec 2014 00:00:00 +0000

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, however minor firmware such as disk and I/O cards only should be able to be rolled.

SPARC Logical Domains: Live Migration

Tue, 09 Dec 2014 00:00:00 +0000

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 could literally utilize any compatible hardware at the drop of the hat.

Solaris Virtualization: Using Logical Domains on Solaris 11 Part Two

Tue, 07 Aug 2012 00:00:00 +0000

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

bash

ldm add-domain t4-g1

Configure Devices

We will need to add devices to our newly created domain. Here we will add virtual CPUs, memory, and a network device.

Solaris Virtualization: Using Logical Domains on Solaris 11 Part One

Mon, 06 Aug 2012 00:00:00 +0000

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 One we will go over what it takes to configure a Solaris 11 installation to be a Logical Domains hypervisor. In Part Two we will document defining and configuring Logical Domains. In Part Three we will discuss connecting to the Logical Domain in order to perform an installation of the operating system.
