A Stack? 6

One Stack 7

Another Stack 8

Obviously. 9

Obviously not. 10

🎊 Storage Network Compute 11

🎊 Monitoring Logging Auditing Authentication Storage Network Compute Updating … 12

Need/Want Everything (sorry, CC BY unknown 2.0) 14

Virtualization and containers ( giphy ) 15

N=2 16

Maybe. 17

KubeVirt 18

Kubernetes virtualization API and runtime add-on # If optimistic|hero|curious and cluster owner, then $ kubecuddle create -f run.kubevirt.io/v/0.2.0.yaml $ kubecuddle create -f run.kubevirt.io/v/0.2.0-on-minikube.yaml ( wallpapercave ) 19

Single API entrypoint $ kubecuddle get pods $ kubecuddle get vms 20

… inheriting authentication & authorization 21

… aligned logging & metrics 22

… aligned metric exposure 23

So cloud-native that it hurts thrills Independent life-cycle, just like any other cloud-native app. No need to bother the host, who needs it anyway?! Everybody. (sorry, CC BY unknown 2.0) 24

The famous 80% and unlucky 20. 25

VirtualMachine kind: VirtualMachine metadata: name: awesome2 spec: domain: devices: … nodeSelector: cpu: fast status: phase: Running 26

We get scheduled like other pods 27

We have display and console access! 28

Our network works like a pod's network ~ SOON ~ 29

PersistentVolumes are our disks ~ SOON ~ 30

We've got live migration! ~ SOON AGAIN ~ 31

There is a price. 32

OBEY & PAY to Kubernetes (and if you wear one of those hats) Not that bad actually. It's a chance to think. 33

"Kubernetes first, virtualization second." -- The Razor Well, we'll not forget you, virtualization. ( jshj , CC BY NC 2.0) 34

Obey: Network Price: No pipes SOON: Pipes Price? 35

Obey: Scheduling Price: No rescheduling SOON: Descheduler Price? 36

Obey: NUMA Awareness Price: Less optimized SOON: CPU Manager Price? 37

How far will it go? Not endless, there are di ff erences. 38

Try (with minikube ) $ kubectl create \ -f run.kubevirt.io/v/0.2.0-on-minikube.yaml \ -f manifests/demo-pv.yaml 39

Going forward Get it to you ! Stabilize Contribute to Kubernetes ( cuatrok , CC BY SA 2.0) 40
