-Subject: [PATCH] hw/pvrdma: Protect against buggy or malicious guest driver
-
-Guest driver might execute HW commands when shared buffers are not yet
-allocated.
-This could happen on purpose (malicious guest) or because of some other
-guest/host address mapping error.
-We need to protect againts such case.
