Yes, I know of a few setups that are using dnsdist with Keepalived. 
There is nothing particular to do on dnsdist's side to make it work, 
which is why it's not mentioned in the documentation.
We will of course accept pull requests updating the documentation if you 
find out that some parts could use some words, though :)
