KubeVirt installation on public cloud/upstream clusters
The default node pool VMs (worker nodes) in Azure do not have Intel virtualization extensions (VT-x) enabled. When trying to create a guest VM, you will see that the kubevirt VM pod will be unschedulable with the following error message: To fix this, you need to create a new node pool using an Azure VM flavor that has VT-x extensions. (those from the Ds_v3 series all have them)
