Hello, I would really like to have the ability of adding ISOs as cd-rom drives, to my VMs without the need to restart. I am using harvester 1.5.1, and found the kubevirt documentation about hotplug volumes. I enabled the

DeclarativeHotplugVolumes

flag in my harvester cluster and attempted to create a VM with an empty CD-ROM. The Kubevirt admission webhook promptly refuses my VM with the following error message:

Copy code

"admission webhook \"virtualmachine-validator.kubevirt.io\" denied the request: spec.template.spec.domain.devices.disks[3].Name 'cdrom-1' not found.

Is there any way I could achieve what I am trying to do in Harvester?

Answering my own question: this will not be possible until harvester is updated to use Kubevirt 1.6

The

DeclarativeHotplugVolumes

gate is not supported before Kubevirt 1.6

1.6.0 (Harvester) is running 1.5.2 KubeVirt.

So maybe 1.7.0, but who knows.

Thanks! Yes, I guess I will have to wait for the feature.
