[virt-tools-list] Migration Problems

[Luengffy XUE]

Hi all,

I find this in the docmentation.

Migration requirements

   - A virtualized guest installed on shared networked storage using one of
   the following protocols:
    - Fibre Channel
      - iSCSI
      - NFS
      - GFS2
      - Two or more Red Hat Enterprise Linux systems of the same version
   with the same updates.
   - Both system must have the appropriate ports open.
   - Both systems must have identical network configurations. All bridging
   and network configurations must be exactly the same on both hosts.
   - Shared storage must mount at the same location on source and
   destination systems. The mounted directory name must be identical.


What I am not understand is whether the migrate can only take place based on
the shared storage.
If migrate take place in this way, in my  opinion, I think it is not the
complete migration.
It is just change the host such as the pointer.
I think the complete migration is "migrate the VM from source host to the
destination host and the storge is independent . It is from one storge of
source host the another storge of destination host. "
