Exercise 8: The Final Showdown¶

Time: 25 min
Previous: Exercise 7: The Stampede
Next: Exercise 9: A New Horizon

The legacy vendor wants forty percent more for the renewal. Sarah declines. The last critical workload, legacy-ledger-vm, must land on SUSE Virtualization while the old world is still running.

Tip: The customer Rodeo image includes a ready ISAware migration source and a live legacy VM. A clean rodeo up lab does not. Below you walk the real Migration UI path, then complete the same verification steps on a stand-in ledger VM so every skill still sticks.

8.1 Explore the migration bridge¶

In Harvester: Advanced → Migration → Sources.

On the Instruqt Rodeo you would see isaware-legacy-01 in Ready state, credentials to the old hypervisor, no agent required on the source.

On this self-hosted lab the list is empty unless you point a source at a real vSphere/ISAware-compatible endpoint. Open Create and read the fields (source type, endpoint, credentials) so you know what production needs. Cancel without saving if you have no legacy cluster.

8.2 How extraction works (when a source exists)¶

Migrations → Create (reference, use when a source is Ready):

Setting	Value
Source Type	ISAware (or the type your source uses)
Source VM	`legacy-ledger-vm`
Target Network	`prod/service` (or mgmt / default lab network)

The importer copies disks, converts them to Longhorn volumes, and registers a native Harvester VM. Progress is visible on the Migrations page.

8.3 Workshop path: stand in the migrated ledger¶

Create (or reuse) a VM that represents the extracted workload:

Field	Value
Name	`legacy-ledger-vm`
Namespace	`prod`
Network	`prod/service`
Image / SSH	same foundations as Exercise 2

Wait until it is Running. Open Console. The migrated ledger is alive on the new fabric.

8.4 Enable guest telemetry¶

SSH into the VM and start the QEMU guest agent:

ssh opensuse@MIGRATED_VM_IP
sudo systemctl enable --now qemu-guest-agent
exit

Back in the UI, the VM should report richer guest info (IP, memory tools) once the agent is up.

8.5 Treat the refugee like a citizen¶

Prove day-one parity on the new platform:

Take a snapshot named post-migration-baseline.
Live-migrate legacy-ledger-vm to another node (Exercise 4 skills).
Optional CLI:

kubectl get vm -n prod | grep legacy-ledger
kubectl get virtualmachineimports -A    # empty unless a real import ran

On ISAware, live migration was often a licensed add-on. Here it is standard.
