Description Juan Quintela 2010-07-08 10:53:44 UTC
Description of problem:

There is no way to add optional information to migration sections.  This means that any change in section format means that we are not able to migrate backwards inside rhel6.x.

This is the upstream solution (submitted) and previous discussions agreed with the design. This mechanism will allow us to be able to fix things later.

IDE was broken due to lack of subsections (it is not trivial to get that right).  I also have pushed this changes upstream.

Any suggestions on how we could verify the bug?

Basically, until no new development, in terms of functionality there is no change. This code adds some flexibility to the migration protocol so it will be able to ignore some subsections (that are not there yet).

The in flight IDE state was (re)implemented using this framework so it is worth to test that migration of IDE disks during load still works.

Verified in qemu-kvm-

Migrate Guest with IDE disks with load via tcp protocol, unix protocol, compressed file,std file.

Actual Results:
After Migration, Guest still works.

The issues has already been fixed ,change status to VERIFIED.
