Hidora's customers are leaving VMware now, and a tenant has to be able to
import their own machines without a platform administrator. The chart
approach could not express that: a tenant can neither create the Secret
holding vCenter credentials nor name the VDDK image, so both had to come
from somewhere they cannot reach.
Two CRDs in a new `forklift.cozystack.io` group, split by lifecycle. A
VMImportSource is a long-lived connection -- type, endpoint, credentials,
readiness -- and a VMImportTask is the one-shot operation that names
machines and produces VMDisks and VMInstances. The outputs carry no owner
reference back to the task, so deleting a finished import leaves the
machines alone. Konveyor Forklift does the transfer underneath; the
controller renders its objects, mirrors its verdicts, and hands each
finished volume into a VMDisk without copying it.
What a live vCenter migration forced out, and no amount of source reading
would have:
- A guest copied verbatim keeps the drivers it had under VMware and no
virtio, so on a virtio disk it does not fail the import -- it succeeds
and then does not boot. Imported disks go on SATA.
- VDDK connects straight to the ESXi host at the address vCenter
advertises, which is routinely unreachable, and on the first cluster
collided with the Service CIDR. `spec.hosts` redirects per host.
- Firmware must be carried across or a UEFI guest imports as BIOS and
never boots (stacked on #3002).
- Deleting a task mid-transfer orphaned its DataVolume; a finalizer now
removes the engine's volumes and leaves the outputs.
The console gains a Migration section: connections are editable, and the
VM field is a picker built from a machine list the controller publishes,
since the aggregated API cannot reach the inventory and should not hold a
source's credentials to try. Two general mechanisms fall out of that --
an option source may take an argument, and one named in a CRD annotation
may reference a sibling field.
