We allocate the snapshot file on an active storage, so it should not
be necessary to activate it again.
Note: see __snapshot_save_vmstate and foreach_writable_storage

> savevm-start calls the path function of the storage which in case
> returns a means for savevm-start to access the vm state disk which is
> all as should be. However, I have discovered that savevm-start does not
> call the storage function activate_volume neither prior nor after the
> call to the function path. This leads to the following questions:
> 1) Should a call to path in a storage plugin always implicitly have the
> storage plugin activate the volume?
no
> 2) Should savevm-start call the storage plugins function activate_volume
> before or after calling path?
no
