** Description changed:
+ [impact]
+
+ 40-vm-hotadd.rules unconditionally tries onlining memory, which results
+ in logged error messages if the memory is already online
+
+ [test case]
+
+ since this rules file restricts operation to only hyper-v or xen guests,
+ boot a hyper-v or xen vm
will do, thnx
