调研方向
Start by tracing the KVM agent’s libvirt migration job information, the management server’s migrate work job and updateAsyncJobStatus(), the VM response API, and the instance page and VM.MIGRATE event handling. The issue describes the expected progress fields, display, and event summaries, but names no files or tests; first map the migration flow across these components. Done means progress is polled and exposed during migration, shown in the UI, and summarized in completion and error events.

描述
The required feature described as a wish
SUMMARY
During a live migration the UI only shows the instance as Migrating, so admins have to run virsh domjobinfo on the source host to see how far along it is or whether it has stalled.
This proposes showing migration progress for KVM first. The API field is hypervisor-neutral, so VMware, XenServer and others can add it later from their own task progress.
PROPOSAL
- KVM agent: new command that returns the libvirt domain job info (disk and memory processed / remaining / total).
- Management server: poll the source host every few seconds while the migrate work job runs, and store the result on the job with
updateAsyncJobStatus(). - API: admin-only
migrationprogresson the VM response while the state isMigrating, read from the pendingvm_work_job. Percent is always set and the byte/rate figures are optional, since other hypervisors only report a percentage. - UI: progress bar under Status on the instance page with percentage, "x of y complete", estimated time remaining and transfer rate in MB/s. When volumes migrate with the VM, disks and memory get separate bars; libvirt already splits them in the same job info (
file*/mem*). Mock-up attached. - Events: append a summary to the
VM.MIGRATECompleted event description (data transferred, duration, average rate), and on Error - a record of how far it got and a short reason (e.g. timed out and not converging, destination unreachable). Sizes, rates and reason category only. I wouldn't include host or storage names, since the event can be visible to the VM owner.
Happy to work on a PR if this approach is acceptable.
