And Dietmar's reply in that thread:

Oops. 

I don't have this problem (I started with 1.4), but I thought that the 
migration features would allow me to upgrade the physical nodes by 
iteratevily vacating a physical node, upgrading it, and then migrating the 
VMs back if the upgrade goes smoothly (and then, proceed to the next node).

Was I wrong to think that'd be possible? (now that I think about it, kernel 
differences may make impossible at least the live migration, but not 
necessarily the offline)
