Migration between kubevirt clusters - Source version is not supported

[jsakil14]

Hello , I am back here after successfully installing and running a migration plan between Vmware & kubevirt cluster - Now , I am testing different use cases as below:

1. Since , we would have vmtools installed in source machine , do we need to add the qemu agent for kubevirt side of things ? If so , do we go about adding hooks for uninstall of vmtools & install of qemu agent on the destination VM ? Any directions for this
2. I was testing the inter-kubevirt cluster migrations , but was getting this error -SOURCE VERSION IS NOT FOUND - I believe it is checking for k8s version which I have listed below and as per requirements.

Source:

k version --short Flag --short has been deprecated, and will be removed in the future. The --short output will become the default. Client Version: v1.25.10 Kustomize Version: v4.5.7 Server Version: v1.25.10

4. Is it possible to migrate the vms from kubevirt to vmware & do we have any work in progress for live migration in future with shared disks like DBA for quourum disks.

hi,

1. forklift use https://www.libguestfs.org/virt-v2v.1.html , it will try to update the guest agent
2. for supported version see:
   https://github.com/kubev2v/forklift/blob/ee060638e7f3a16ba305c8c3978532d2cdc13b08/pkg/controller/plan/validation.go#L971

Thanks , it was helpful.

On the other question , I wanted to test if we have any tool similar to forklift which can do the migration other way ( KubeVirt --> VMware) , since we may need to port the VM backwards , if at all we needed - so exploring that options as well. Any recommendations - for now , I have got qemu-img which can create vmdk something like below :

Use qemu-img to convert to VMDK then use something like vCenter or VMWare OVF Tool to make into OVA.

qemu-img convert -f qcow2 -O vmdk yourimage.qcow2 destination.vmdk

But was looking for something which can do as a bulk or what forklift does and extend its features to this ask.

@yaacov thanks , as per https://github.com/kubev2v/forklift/blob/ee060638e7f3a16ba305c8c3978532d2cdc13b08/pkg/controller/plan/validation.go#L971 it just says version to be minimum 1.26 , I am using kubevirt cluster with v1.1.0 , how do we correlate kubernetes version with kubevirt , in my case?

also , looking for some direction with On the other question , I wanted to test if we have any tool similar to forklift which can do the migration other way ( KubeVirt --> VMware) , since we may need to port the VM backwards , if at all we needed - so exploring that options as well.
