This is a hands-on workshop on KubeVirt.
The workshop consists of the following steps:
we should deploy kubevirt web ui as part of the lab
we should either use a lighter image or use uploader to use a prefetched and local image
PATH=/usr/local/sbin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
That way the student doesn't have to do ./virtctl?
@karmab what do you think?
substitute pod name
k8s version should be updated here in 1.13 is quite old
Password not allowed
setfacl -m user:107:rwx /root/openshift.local.pv/pv*
Looks like its now in /root/openshift.local.clusterup/openshift.local.pv. Will submit a PR.
Currently it only contains links but it would be nice to have an introduction, tutorial objectives, list of resources, contact details, etc.
Also, the links should have bullet points.
As per ,

[root@shegde-master0 ~]# oc get vms

[root@shegde-master0 ~]# virtctl console hegde-vm
Can't connect to websocket (500):
if a student runs oc logout they will get an error about no token.
Some of the python code written in the kubevirt-tutorial-presubmit-lab-testing-k8s is still in 2.7, and the following warning is appearing:
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.
That code has to be ported to python 3.

In lab 9, a process to create VM's from a GUI, the section says to select an OS as fedora29 but we dont have this in the drop down.
Under Using the kubevirt web ui
Create a Virtual Machine
In the Basic Settings configure with the following
Name: vm3
Namespace: myproject
Provision Source: Container
Container Image: docker.io/kubevirt/cirros-registry-disk-demo:latest
Operating System: fedora29 - No OS with fedora available.
Memory: 1 - No option to select Memory
CPUs: 1 - No option to select CPU count
Workload Profile: generic

Follow other KubeVirt repositories to use more respectful language by switching from master to main.
In lab 8, when we talk about Confirm connectivity section
Through cloudinit, we also configured fedora-multus-1 vm to have ip 11.0.0.5 and fedora-multus-1 vm to have ip 11.0.0.6 so try to ping or ssh between them
Here, vm name with IP 11.0.0.6 should be fedora-multus-2 instead of fedora-multus-1
