This is the first blog post in a series about running mixed x86 and ARM64 Kubernetes clusters, starting with a general architectural overview and then moving to detailed step by step instructions. Kubernetes doesn’t need any introduction at this point, as it became the de facto standard container orchestration system. If you, dear reader, developed…
One might argue what is the point in running a cloud infrastructure software like OpenStack on top of another one, namely the Azure public cloud as in this blog post. The main use cases are typically testing and API compatibility, but as Azure nested virtualization and pass-through features came a long way recently in terms…
In part 2 of this series about OpenStack on ARM64, we got to the point where our cloud is fully deployed with all the Compute (VMs), Software Defined Networking (SDN) and Software Defined Storage (SDS) up and running. One additional component that we want to add is a Load Balancer as a Service (LBaaS), which…
In the previous blog post we created the ARM OpenStack Kolla container images and we can now proceed with deploying OpenStack. The host is a Lenovo server with an Ampere Computing eMAG 32 cores Armv8 64-bit CPU, running Ubuntu Server 20.04. For simplicity, this will be an “All-in-One” deployment, where all OpenStack components run on…
This is the beginning of a short series detailing how to deploy OpenStack on ARM64, using Docker containers with Kolla and Kolla-ansible. The objective of this first post is to create the ARM64 container images and push them to a remote registry in order to be used later on, when deploying our OpenStack cloud. We…
Platform and cloud interoperability has come a long way. IaaS and unstructured PaaS options such as OpenStack and Kubernetes can be combined to create cloud-native applications. In this port we’re going to show how Kubernetes can de deployed on an OpenStack cloud infrastructure.
We’ve added support for RemoteFX for Windows / Hyper-V Server 2012 R2 back in Kilo, but the highly anticipated Windows / Hyper-V Server 2016 comes with some new nifty features for which we’re excited about! In case you are not familiar with this feature, it allows you to virtualize your GPUs and share them across…
Windows Server 2016 is gaining significant traction in OpenStack and other clouds, thanks to the support for Windows Docker containers and lots of other new features. While there’s no OpenStack Windows Server 2016 image directly available for download, the good news is that our automated build scripts will do all the work for you. All you need is a…
OpenStack is a great technology, but it can be a bit cumbersome to deploy and manage without the proper tools. One easy solution to address this issue is to deploy OpenStack services using pre-built Docker containers. Kolla is a set of deployment tools for OpenStack, consisting in the Kolla project itself, for generating OpenStack Docker images, and…
We’re getting quite a few questions about how to set the admin password in OpenStack Windows instances, so let’s clarify the available options. nova get-password The secure and proper way to set passwords in OpenStack Windows instances is by letting Cloudbase-Init generate a random password and post it encrypted on the Nova metadata service. The password can…
before reading the conclusions, we recommend to read the previous posts in this series if you want to know more details about the environment and the test scenarios: Introduction, Scenario 1, Scenario 2, Scenario 3. Conclusions It’s time to discuss all the results obtained so far. The table below show the average time expressed in seconds…
We have seen how to setup the benchmarking environment and two simple scenarios (Scenario 1, Scenario 2) in the previous blogposts of this series. This time we are going to add Hadoop to the mix to test a workload with significant memory, CPU and I/O impact. Scenario 3 The image used for this…
We talked about setting up the environment for benchmarking and we have seen in the previous part a simple OpenStack scenario. In this part we are going to continue by adding more complexity to the use case being tested. Scenario 2 In the second scenario a few intermediate steps have been added to increase the…
In the previous part of this OpenStack KVM vs Hyper-V compute benchmarking series we talked about how to setup the testing environment and how to run some scenarios. Time for some results! Scenario 1 To begin with, we started with a basic KVM vs Hyper-V scenario: Ask Nova to boot a VM Wait until Nova…
OpenStack Newton has been recently released. During this cycle we did quite some work on increasing the performance and overall reliability of our Windows and Hyper-V OpenStack compute drivers. This is the first post in a series where we are going to share some of our Hyper-V vs KVM benchmarking results for this OpenStack release, get…
Azure Service Fabric is a distributed systems platform that makes it easy to package, deploy, and manage scalable and reliable microservices. It can be deployed on Azure, but also on-premise, thus making OpenStack a great choice for the latter. We are going to use Juju to deploy our Azure Service Fabric cluster directly on OpenStack…
A Shielded VM is a Hyper-V generation 2 VM that has a virtual TPM, is encrypted using BitLocker and can only run on healthy and approved hosts in the fabric. It is protected from inspection, tampering and theft from malicious fabric admins and host malware, guaranteeing the security of the virtual machines running in an…
Migrating existing workloads between clouds is a necessity for a large number of use cases, especially for user moving from traditional virtualization technologies like VMware vSphere or Microsoft System Center VMM to Azure / Azure Stack, OpenStack, Amazon AWS or Google Cloud. Furthermore, cloud to cloud migrations, like AWS to Azure are also a common requirement. Project Coriolis™ addresses exactly those…
There’s quite some documentation already available on how to run Windows Nano Server on Hyper-V or bare metal, but what about other hypervisors? Here at Cloudbase Solutions we often need to build images for different platforms, so why not automate the process in a simple way for all relevant scenarios, including, to begin with: bare metal,…
Nano Server is a new installation option for Windows Server 2016, reducing the overall footprint to just a few hundreds MB of disk space. The resulting deployed OS is thus way faster to deploy and to boot, reducing drastically also the overall amount of updates and reboots required during daily management. In short, it’s an OS built for a cloud age and huge leap forward compared to traditional GUI based Windows deployments.
Here at Cloudbase, we use a lot of Intel Next Unit of Computing (NUC) for our internal testing and development work. The NUC is a small form factor computer, designed and manufactured by Intel, very compact and powerful, sporting a Haswell i5 processor, up to 16 GB of RAM and a mSATA SSD. You can see…
Here’s our second post in the RDO + Hyper-V series targeting Havana and automation. We had lots of great feedbacks about the first post, along with many requests about how to troubleshoot network connectivity issues that arise quite often when you configure a complex environment like a multi-node OpenStack deployment, especially for the first time! Although…
Windows Server 2012 and Windows Storage Server 2012 offer an integrated iSCSI Target service that can be used with Cinder Volume in your stack. Being entirely a software solution, consider it in particular for mid sized networks where the costs of a SAN might be excessive. One of the great advantages of integrating Windows solutions…
DevStack is without any doubt one of the easiest ways to set up an OpenStack environment for testing or development purposes (no production!!). It’s also a great way to test the Hyper-V Nova Compute and Quantum Grizzly beta versions that we are releasing these days! 🙂 Hyper-V Server 2012 is free and can be downloaded…
After installing DevStack on your Ubuntu machine, when trying to access the OpenStack Dashboard (Horizon) you might get the following error: Exception Value: /usr/bin/env: node: No such file or directory Here’s the solution, tested on 12.04 and 12.10:
|
1 2 3 |
sudo apt-get install node-less mkdir -p /opt/stack/horizon/bin/less ln -s /usr/bin/lessc /opt/stack/horizon/bin/less/lessc |
On Ubuntu 12.10 you will also need nodejs-legacy:

apt-get install nodejs-legacy |
In a number of scenarios it’s very useful to have different hypervisors in your OpenStack infrastructure, for example you might have KVM or XEN for Linux images and Hyper-V for Windows images. How can you tell Nova Scheduler to associate a given Glance image to a specific hypervisor? The answer is provided by a filter…
We did a lot of work this year on OpenStack and Hyper-V integration, with the result of bringing back Hyper-V in the Nova sources in time for the Folsom release. We are currently working on a lot of cool features to be released in time for Grizzly, so stay tuned! One of our goals was…
Accessing Microsoft’s Hyper-V console is typically performed by running Hyper-V Manager / vmconnect on a Windows Server host or Windows 7 / 8 equipped with RSAT. There are unfortunately quite a few limitations in this approach, including the fact that is not available on the Hyper-V host itself or on other operating systems. Hyper-V console…
Here we go, brand new site and great new products to show at the OpenStack Summit in San Diego. 🙂 We did a huge amount of work lately bringing OpenStack to the Microsoft world, including the new Hyper-V Nova Compute driver, accepted in the OpenStack source code in time for the Folsom release!
