Hi,

I still can figure out why it should be necessary to migrate the vm if the storage is migrated to another host?

Especially in the situation where a host has more than one disk and you then migrate one of the disks. Should the vm still be migrated then? what about the remaining disks, should they be migrate as well?

In my opinion the user should decide whether to migrate the vm together with the storage or maintain the vm at the host where it is currently running.

Hi,

I'm begin to look for storage migration implementation,

do you think we need to extend "qm migrate" ?

something like:

qm migrate <vmid> <target> --virtio0 local:raw --virtio1 nfs:qcow2
--virtio3 rbd:

1) if targethost = sourcehost , then we only migrate storage

2) if targethost != sourcehost, we migrate the vm + migrate storage(with nbd)


what do you think ? Does it make sense ?


1) should be easy to add on top of my clones patches

2) require a little more work to implement nbd
