Hi Thomas,

> Yes, to be totally save, one should use drbdsetup to change this value temporarily only. So workflow would look something like that:
> 1.) drbdsetup net-options <resource> --allow-two-primaries yes
> 2.) xl migrate --live <domu> <host>
> 3.) drbdsetup net-options <resource> --allow-two-primaries no

I  will script following this wise advice :)

Many thanks for the suggestion...
