Solving GPU Passthrough Memory Addressing in OpenStack

Delivering Accelerator enabled Developer Cloud Functionality on Rackspace OpenStack Flex.

When AMD launched the AMD Developer Cloud, we took notice. Here was a streamlined platform giving developers instant access to high-performance MI300X GPUs, complete with pre-configured containers, Jupyter environments, and pay-as-you-go pricing. The offering resonated with the AI/ML community because it eliminated friction: spin up a GPU instance, start training, destroy it when done.

Getting Started with GPU Compute on Rackspace OpenStack Flex

Your instance is up, your GPU is attached, and now you're staring at a blank terminal wondering what's next. Time to get Clouding.

Rackspace OpenStack Flex delivers GPU-enabled compute instances with real hardware acceleration, not the "GPU-adjacent" experience you might get elsewhere. Whether you're running inference workloads, training models, or just need raw parallel compute power, getting your instance properly configured is the difference between frustration and actual productivity.

Enabling Hybrid Cloud with RackConnect Global

RackConnect® Global (RCG) is a software-defined, multi-cloud interconnection platform that links Rackspace Technology customers with other Rackspace data centers, third-party data centers, and third-party clouds through direct, private, low-latency, virtual connections. All traffic flowing between every endpoint avoids the public Internet and instead rides the Rackspace private backbone.

Within OpenStack Flex, Rackspace's next-generation multi-tenant public cloud, RackConnect Global allows customers to connect their virtual machine instances to third-party datacenters or to dedicated (baremetal) server environments within Rackspace DCs. RackConnect Global can enable customers to leverage the elasticity of public cloud while utilizing dedicated hardware gateways and firewalls, or simply add routes to remote resources over the RCG link.

CAPI powered TALOS clusters on Rackspace OpenStack Flex

We detail how to build immutable, secure, and minimal Kubernetes clusters by combining Cluster API (CAPI) with TALOS OS. This powerful stack allows you to leverage the cloud-agnostic management capabilities of CAPI while benefiting from TALOS's minimal attack surface. Deploying on RackSpace OpenStack Flex grants you complete control over your underlying infrastructure, maximizing resource efficiency and providing a production-ready cloud-native environment. This integration simplifies day-2 operations and delivers enterprise-grade security for your private cloud.

Building a VyOS image for use in Rackspace OpenStack Flex

In the beginning there was Vyatta, a free software-based alternative to hardware-based routing products offered by network beheamoths like Cisco and Juniper. After being acquired by Brocade, development of Vyatta Core, the community edition of the product, began to languish until its abandonment shortly thereafter. VyOS formed from the ashes and has continued to build upon the core to deliver a highly-functional and highly-competitive routing platform.

Deploying Horizon 8 with Manual Pools and Farms on Rackspace OpenStack

omnissa-horizon

By utiliizing manual pools and farms in Horizon 8, organizations can leverage infrastructure platforms not natively supported for automated pool provisioning. This blog post details a real-world deployment using manual pools and farms running on OpenStack and was inspired by the blog post "Horizon 8 with manual pools and farms – using alternative hypervisors," written by Omnissa, which introduced how their incredible VDI solution can be leveraged on non-proprietary platforms.

VMware to OpenStack Migration using virt-v2v

This document describes the path to migrate a virtual machine from VMware to OpenStack using virt-v2v vpx. You should use vddk plugins to make this process fast for which link is mentioned in the doc.

I used OpenStack volume on the destination cloud however one can select glance or local basis upon their used cases.
