I have configured Percona mysql master slave replication successfully. I have one another Percona mysql server. Can I possible to create multi master with single slave replication?
Means can I possible to replicate two master server into a single slave server?

I am using all my Percona mysql server is 5.5.29

It is not possible with MySQL or Percona Server. You can do it with the alpha version of MariaDB 10.
