v2v-job v0.2.0 POC for importing VMs into KubeVirt

KubeVirt becomes usable. And to make it easier to use it would be nice to be able to import existing VMs. After all migration is a strong point of KubeVirt.

virt-v2v is the tool of choice to convert some guest to run on the KVM hypervisor. What a great fit.

Thus recently I started a little POC to check if this would really work.

This post is just to wrap it up, as I just tagged v0.2.0 and finished a nice OVA import.

What the POC does:

Take an URL pointing to an OVA
Download and convert the OVA to a domxml and raw disk image
Create a PVC and move the raw disk image to it
Create an OfflineVirtualMachine from the domxml using xslt

This is pretty straight forward and currently living in a Job which can be found here: https://github.com/fabiand/v2v-job

It’s actually using an OpenShift Template, but only works on Kubernetes so far, because I didn’t finish the RBAC profiles. However, using the oc tool you can even run it on Kubernetes without Template support by using:

$ oc process --local -f manifests/template.yaml \
    -p SOURCE_TYPE=ova \
    -p SOURCE_NAME=http://192.168.42.1:8000/my.ova \
  | kubectl apply -f -
serviceaccount "kubevirt-privileged" created
job "v2v" created

The interested reader can take a peek at the whole process in this log.

And btw - This little but awesome patch on libguestfs by Pino - will help this job to auto-detect - well, guess - the the guest operating system and set the OfflineVirtualMachine annotations correctly, in order to then - at runtime - apply the right VirtualMachinePresets, in order to launch the guest with optimized defaults.
