Learn KubeVirt: Deep Dive for VMware vSphere Admins
A deep dive into KubeVirt for vSphere admins. Learn VM creation, storage, networking, and operations mapped to familiar VMware concepts.
Oh, that's a nice and long post on #kubevirt written for #vSphere admins who might consider migrating:

As said, #redhat is well placed here. For those admins looking into #openshift #virtualization , NetObserv can help monitor closely your workloads network.

Native network segmentation for virtualization workloads | Red Hat Developer
Discover the UDN feature for network segmentation in OpenShift, and learn how it addresses virtualization workload challenges in the Kubernetes platform
One more thing, that isn't mentionned in the above article: the recent versions of ovn-kubernetes have a new feature called UDN for User Defined Network, which is basically segmentation. More about that here: developers.redhat.com/articles/202...

About
NetObserv aka Network Observability is a set of components used to observe network traffic by generating NetFlows from eBPF agents, enrich those flows using a configurable pipeline that is Kubernetes-...
Interesting post from #netflix: netflixtechblog.com/how-netflix-... on #eBPF based #observability with network flows.
If you're not Netflix but still are interested, you can also take a look at what we're doing with NetObserv: netobserv.io/about/

- OVN is improving its observability, for instance it can emit events such as when a network policy blocks/accept traffic. NetObserv can leverage and display that.
It's only Tech Preview at the moment, so you'll need to wait a bit before having it on a prod cluster.

UserDefinedNetwork CR - Multiple networks | Networking | OpenShift Container Platform 4.18
There are also cool new features related to ovn-kubernetes (you won't get them if you use a different CNI) :
- As #OpenShift introduces new User Defined Networks (docs.openshift.com/container-pl...), which offers a much better isolation, NetObserv can visualize them as topologies and more...

Enhancing NetObserv By Introducing Multi Rules Flow filtering capability in eBPF
NetObserv eBPF Flows Filtering
... and more filtering options in the #eBPF agent. For example, you can now decide to sample ALL external traffic while maintaining a 1:50 ratio on internal traffic, to save resources without compromising what matters most.

Performance improvements in 1.8
How we reached -50% CPU on the eBPF agent
One of the cool things that you can immediately notice if you upgrade from 1.7, is the performance improvement, especially on the eBPF Agent CPU. More on this here: netobserv.io/posts/perfor...

Enhancing NetObserv for Kubernetes Service Flows using eBPF
NetObserv Packet Translation provide enriched service endpoint POD information
📢 New blog post on how to correlate pods and services traffic in #Kubernetes : netobserv.io/posts/enhanc...
This feature will be coming soon, in netobserv 1.8 (already merged in the main branch).
It's achieved by hooking into the #linux #kernel conntracking, with #ebpf .

NetObserv: network observability on Kubernetes / OpenShift
Components for Network Observability, unleashing eBPF super-power.
Good morning Bluesky !
#Introduction
This is a developer account of the NetObserv tool. It's an #opensource software, born at #redhat, that provides network observability through #ebpf probes in the Linux kernel. It's mostly designed for #Kubernetes / #OpenShift
