See the Explanation.
Explanation:
1. Create the NAD YAML:
apiVersion: k8s.cni.cncf.io/v1
kind: NetworkAttachmentDefinition
metadata:
name: ext-bridge-net
namespace: default
spec:
config: '{
"cniVersion": "0.3.1",
"type": "bridge",
"bridge": "br-ext",
"ipam": {
"type": "dhcp"
}
}'
2. Apply it: oc apply -f nad.yaml
3. Confirm with: oc get net-attach-def
4. Validate bridge exists on node.
5. Check for DHCP connectivity later in VM.

See the Explanation.
Explanation:
1. Ensure eviction-strategy: LiveMigrate is set.
2. Start the VM and confirm it's on a node:
oc get vmi -o wide
3. Drain the node:
oc adm drain <node> --force --ignore-daemonsets --delete-emptydir-data
4. Watch
migration: oc
get vmim -w
5. Confirm new node assignment.

See the Explanation.
Explanation:
1. Create egress policy:
policyTypes:
-
Egr
ess
egr
ess
:
- to:
- ipBlock:
cidr: 10.0.0.0/16
2. Apply to VMs using kubevirt.io: virt-launcher selector.
3. Test connectivity to allowed IPs and block others.

See the Explanation.
Explanation:
1. Run:
oc get vm <vm-name> -o jsonpath='{.spec.runStrategy}'
2. Common values include Always, Manual, RerunOnFailure, or Halted.
3. Alternatively, describe the VM:
oc describe vm <vm-name>
4. Look under RunStrategy section.
5. This determines the automatic start behavior of the VM.

See the Explanation.
Explanation:
1. Define a parameter:
- name:
DISK_SIZE
required: true
2. Use in dataVolumeTemplates:
resources:
requests:
storage: "${DISK_SIZE}"
3. Set value via oc process -p DISK_SIZE=15Gi
4. Apply result.
5. Enables size tuning per VM.
