[pve-devel] [PATCH 1/3] add live storage migration with vm migration

[Alexandre DERUMIER]

I can confirm that it's working !


1) start remote vm + nbd share
2) start disks mirroring to nbd
4) monitor jobs, and wait until all drives are ready (100% mirror) but does not complete
3) start live migration
4) monitor jobs again, if they are all ready do the complete, do the block-job-complete
5) stop the source vm
6) resume source vm


I'll polish my patches and try to send them tomorrow for review.

Something like that - not sure if that is possible?
