@anandkolli could you describe the problem you encountered?
from demo.

Below are the details:
Yaml file to launch a VM:
metadata:
name: testvm-ephemeral
apiVersion: kubevirt.io/v1alpha1
kind: VirtualMachine
spec:
domain:
devices:
disks:
- type: RegistryDisk:v1alpha

os:

type: qemu
Docker file used to generate the image:
FROM kubevirt/registry-disk-v1alpha
ADD entry-point.sh /
RUN apt-get update && apt-get install -y
bash curl bzip2 qemu-utils qemu-kvm qemu virt-manager virt-viewer &&
mkdir -p /disk &&
rm -rf /var/lib/apt/lists/*
ADD gw-vm.qcow2 /disk
CMD ["/entry-point.sh"]
Pod was successfully launched and was up and running as highlighted:

But I don't see the corresponding VM getting spawned.
below are logs from the pod.

Please let me know if you need any further information.

Did the VM ever attempt to launch? What's the 'kubectl describe vm testvm-ephemeral' output?
from demo.

How long did you wait for the VM to come up?
And what Kubernetes distribution are you using?
Because I also see that the launcher fails to see the qemu process you might want to try https://github.com/kubevirt/kubevirt/releases/tag/v0.3.0-alpha.3 - which has changes in this area (as well as others).

Once I launch the pod I keep waiting and never deleted the pod at all.
Kubernetese version:
root@virt-virtual-machine:~# kubelet --version
Kubernetes v1.8.0
Sure I will take a look and shall get back to you.
Thank you,

Ok.
Actually - Are you using Openhift, Tectonic, vanilla upstream Kubernetes, …?

commented on May 24, 2024
I have installed kubernetes using kubeadm on a single virtual machine.

fabiand
commented on May 24, 2024
Ok, that's what we use as well. please retry with v0.3.0-alpha.3 above.

@anandkolli I need to see the 'kubectl describe vm testvm-ephemeral' output. That's going to give us insight into what happened to the vm. I can tell from the pod description that the pod was at least launched succesfully though
from demo.

Also do you have sample yaml to pass multiple network interface to the virtual machine?
