* We still need to see the vmCreate command used to learn more about the 
issue 
    * We can always implement a hack that checks if the alias attribute exists. 
However, there is probably a deeper issue at hand and this is a good 
opportunity to find and solve it 
    * Dan has a theory that the issue is with migrating a VM from a 3.0 VDSM 
version host to a 3.2 host. Perhaps the balloon device isn't created properly 
at the source host

That's an internal pastebin instance. Could you simply inline the 
answer? Hyperlinks makes a casual reader of the mailing list not 
understand what's going on. 

Note that we need vmCreate command, the response is less 
interesting, thow seeing the whole vdsm thread would not harm.
