Running KubeVirt Workloads with No Additional Privileges - Ľuboslav Pivarč, Red Hat

Kubevirt allows running VMs natively alongside containers on top of Kubernetes, enabling faster containerization, serving legacy workloads, security-sensitive applications, and many more use cases. One of the best practices for running container workloads is to not run them as root, drop all privileges and use Linux Security Modules, such as SELinux or AppArmor. Two years ago Kubevirt started cutting down on capabilities that are used to run VMs with the ultimate goal of requiring no additional capability. Simultaneously Kubevirt integrated seamless SELinux support with its own policy for running VMs. The missing part was running VMs as a rootless user and recently this option landed in Kubevirt. I would like to present what it took to achieve it with Kubernetes and Libvirt and show how important it is to have this use case in mind while implementing new features into the Virtualization stack.

Slirp is Dead, Long Live Slirp! A New Approach to User-mode Networking - Stefano Brivio & Alona Paz, Red Hat

Originally written for completely different purposes, Slirp has conveniently provided user-mode networking to qemu for 18 years. Now consumable as libslirp, it can be set up quickly, almost independently of environment and topology, and is available without special security privileges. But it was never intended for this life.

Enter passt. passt(1) is an implementation of user-mode networking for qemu, focusing on security (no dynamic memory allocation, purpose-written codebase, strict seccomp policy), performance (packet and syscall batching, pre-cooked buffers, minimalistic TCP adaptation), network transparency: contrary to libslirp, NAT is not needed, as the guest inherits addressing and routing from the host via DHCP, NDP, DHCPv6.


The aim is to bring production readiness to user-mode networking with a simpler implementation, written with the specific goal in mind.

This talk presents motivation and history behind the passt project (with a focus on its proposed usage in KubeVirt), status, challenges, future perspectives (such as vhost-user support for further performance improvement, aiming at challenging throughput figures from multi-queue tap devices).

It’s All for the Users. More Durable, Secure, and Pluggable. KubeVirt v0.53 - Alice Frosi, Red Hat

If you liked KubeVirt before, you'll like it even better now, and if you ignored it before, it's time you tried it out. In the last year, KubeVirt has added numerous features, improving scalability, security, storage, network options, and usage for specialized hardware and edge applications. Join the KubeVirt contributors for a brief tour of what's new, including: - Additional traditional storage features for hotplug and snapshots - More mature high performance computing with SRIOV and vNUMA availability - Improved security with unprivileged VMs - Foundation for technical workstations using vGPU slicing - Don’t fear updates with mature Live Migrations - Improved automation with new like Argo CD and Tekton integrations - Rapid Kubernetes tenant cluster using ClusterAPI - On the verge to CNCF Incubator? We'll explain and even demo some of the new features. KubeVirt is going places, join our session to find out how it can help you go places too.

This talk details a real world solution design of a high performance KubeVirt for running mission critical enterprise workload. KubeVirt brings Cloud Native Virtual Machine management to Kubernetes. It unifies workload orchestration across Containers, Virtual Machine, as well as Serverless. Solution designs around KubeVirt, however, are sparse as of date, especially in networking and storage. On the other hand, workloads running on Virtual Machines often demand high performance and isolation enhancement. In this talk, Red Hat and Kubermatic jointly share with the community their customer engagement experiences of building a high performance KubeVirt environment by integrating with Gardener and multiple CNCF projects, including Kubernetes, KubeVirt, Rook, and Kubernetes Network Plumbing Working Group.

KubeVirt extends Kubernetes by allowing users to run virtual machines side to side to containers in their Kubernetes clusters. We will have a whirlwind tour of the architecture, the challenges, the technologies, the components that make this possible.



In this talk we are going to look how KubeVirt allows general purpose management of virtual machines with Kubernetes, alongside application containers. We will see the ways KubeVirt bridges the gap between standard, well known cloud VM management and the brave new world of container orchestration. We will dive in the implementation of KubeVirt, to examine the architecture, and some of the challenges integrating virtual machines with the Kubernetes; we will see the components that make KubeVirt, and some of the tradeoffs involved. We will also peek in two of the most active development topics: the deployment of the whole platform and the monitoring integration with the standard Prometheus infrastructure.

This channel is dedicated to the videos of the GoLab conference.

In this webinar, we will introduce KubeVirt and what VMs with K8s mean for you.

We’ll explore:
1. The architecture of KubeVirt
2. Key use cases where you can already take advantage of Kubevirt to manage legacy applications - Windows apps included! - alongside Kubernetes
3. ‘Gotchas’, tricks and things to be aware of for different implementations
4. How KubeVirt compares with other virtualization frameworks
5. Future of KubeVirt, related projects, and where to start

We would show a demo of an application that is comprised of VMs, Containers, an RDBMS and a LoadBalancer-type Service. We’ll show how HA scenarios for legacy components are automatically handled by Kubernetes and KubeVirt, along with a couple cool surprises!

Introduction to Prow and how we can benefit in KubeVirt from it.

KubeVirt is a robust Virtual Machine management infrastructure that runs on and leverages the core concepts of Kubernetes. The APIs used by KubeVirt will feel very familiar to the seasoned Kubernetes user, but that doesn't cover everybody.

This session is designed to arm users with the practical experience they'll need to deploy Virtual Machines using KubeVirt. We will start with a Virtual Machine running on a local Qemu instance, and using concrete examples, discuss the steps needed to move it to the hybrid cloud. This will cover the Custom Resources used by KubeVirt as well as other considerations such as storage and networking.

Running VM Workloads Side by Side with Container Workloads - Sebastian Scheele, Loodse

On Kubernetes clusters, cloud native workloads and (legacy) VM workloads can run side by side. KubeVirt is a project to bring declarative, Kubernetes-style APIs to VM creation, configuration, and management. In this talk, I will demonstrate how you can use the KubeVirt to set up and manage VM inside of a Kubernetes cluster. I will be describing how KubeVirt leverages CPU virtualization to implement a stronger security architecture for Kubernetes. When combining both approaches, we can run a wider range of workloads, from container cloud-native applications to lift-and-shift applications with KubeVirt.

Intro: KubeVirt BoF - Daniel Gonzalez Nothnagel, SAP & Scott Collier, Red Hat

KubeVirt extends Kubernetes with the ability to run virtual machine workloads, as Kubernetes itself is not able to launch those. To do so KubeVirt introduces dedicated custom resources around virtualization to have enough flexibility to build and tune VMs towards existing and new use-cases. While Kubernetes is a great platform for cloud-native workloads there are also many workloads that require more isolation than containers can provide, or are just in general better served with VMs than with containers. KubeVirt aims at a seamless integration with Kubernetes in order to create one consistent cloud-native API for container and virtual workloads, sharing the same storage, network, and compute resources. In this BoF we will be discussing the basics and different use-cases of KubeVirt and adjacent projects. As an example we will explore how KubeVirt VMs can be used as nodes for a Kubernetes cluster, effectively allowing to run Kubernetes on Kubernetes.

To Learn More: https://sched.co/Ixrt

KVM is a hypervisor offering strong hardware isolation of a guest from it's hosts.

Containers are now a new software based isolation mechanism for workloads, and it might be a small surprise to see that KVM is surfacing in this context quite often.

In this talk we'll look at how KVM is used on the containers and Kubernetes context.
Specifically we'll be looking at the projects KubeVirt, Katacontainers, gVisor, and virtlet, to understand how KVM is used by them to support certain use-cases.

KubeVirt is intended to provide a convergence point for the data center of the future using Kubernetes as an infrastructure fabric for both application container and virtual machine workloads. Using a unified management approach simplifies deployments, allows for better resource utilization, and supports different workloads in a more optimal way.This session will outline how the Kubevirt project seeks to achieve this while using the extensible nature of Kubernetes in a way that provides a develo

Containers seem to be like virtualization, just better. Is it just a matter of time until all VMs will have vanished, and their workloads live their life in containers? Well - This depends on the problem you try to solve. This talk is about looking at why virtualization is still needed in a container world and where it is found. We’ll specifically look at virtualization related projects like ClearContainers, frakti, virtlet, and KubeVirt in the Kubernetes context, their use-cases, commonalities, and differences. After the talk an attendee should have gained overview over which projects exist in the Kubernetes world, and for what they can be used. This talk is for everybody who would like to secure their containers, or who would like to run classical VMs on Kubernetes.

GCE and EC2 provide a great platform to run your own isolated Kubernetes cluster within the cloud. With the Kubernetes Cloud Autoscaler, scaling on-demand of your GCE and EC2 instances can even be done from within your Kubernetes cluster. This session will introduce the Kubernetes Cloud Autoscaler concept and discuss how it is implemented for GCE and EC2. Finally we will have a look at the Cloud Autoscaler backend for KubeVirt, a drop-in Virtualization add-on for Kubernetes, which brings Virtual Machines to Kubernetes to allow you running isolated workloads on your Bare-Metal Kubernetes installation.

KubeVirt - Kubernetes, Virtualization and Your Future Data Center [I] - Itamar Heim & Fabian Deutsch, Red Hat

Kubernetes is a great orchestration tool for containers, but why stop there? Containers and virtual machines are going to co-exist in the data center. Let’s re-envision our virtualization and cloud solutions with Kubernetes as a single underlying platform.

We’ll introduce KubeVirt - a project to converge the future data center using Kubernetes as its infrastructure. We will cover how we are implementing a caring and stateful environment to run pet VMs in containers on top of Kubernetes - without contradicting its core assumptions. We will also be discussing gaps and how we plan to tackle those, drawing on our experience with KVM and and caring for pet VMs (and cats) for many years. The session will also include a demo of how we are doing this today and where we want to go next.
