Daniel,

Thanks for providing this insight, most useful. I'm interpreting this
as: block migration can be used in non-critical applications, mileage
will vary, thorough testing in the particular environment is
recommended. An alternative implementation will come, but the higher
level feature (live-migration without shared storage) is unlikely to
disappear.

Is that a reasonable appraisal?

Would you mind/be-able-to elaborate on those reliability issues? E.g.,
is there anything we can do to mitigate them?
