the recommended filesystem not only depends on
Microsoft, but also on the OS they are talking about:

* The recommended filesystem for RHEL 6 and friends
  is ext4.
  Public available sources say that the recommended 
  filesystem for RHEL 7 will become xfs.

* The recommended filesystem for data on SLES is
  xfs for ~10 years by now.

As is it known, Microsoft and SUSE are working on
Interoperability aspects, and the SLES - HyperV
interaction is one of the areas which is in focus here.

Hope this helps.

so logn -

P.S.: Re-adding the mailinglist to a private
conversation is usually not recommended, but well,
the topic indeed might be of broader interest.
