Is this the same as one of the two existing PoD entries? Expecting not
I'll include it separately today (I'm going to post the update very
shortly) and we can reconcile any duplication for next week.

Hypervisor:
    * [BUG(?)] Under certain conditions, the p2m_pod_sweep code will
      stop halfway through searching, causing a guest to crash even if
      there was zeroed memory available.  This is NOT a regression
      from 4.1, and is a very rare case, so probably shouldn't be a
      blocker.  (In fact, I'd be open to the idea that it should wait
      until after the release to get more testing.)
            (George Dunlap)

Tools:
    * [BUG(?)] If domain 0 attempts to access a guests' memory before
      it is finished being built, and it is being built in PoD mode,
      this may cause the guest to crash.  Again, this is NOT a
      regression from 4.1.  Furthermore, it's only been reported
      (AIUI) by a customer of SuSE; so it shoudn't be a blocker.
      (Again, I'd be open to the idea that it should wait until after
      the release to get more testing.)

I'll make them all nice to have for now, let me know if you decide some
of them should be blockers.

Ian.
