You simply tell Solr about all your zookeeper servers on startup, using
the zkHost property.  Here's the format of that property:

server1:port,server2:port,server3:port/solr1

The /solr1 part (the ZK chroot) is optional, but I recommend it ... it
can be just about any text you like, starting with a forward slash.
What this does is put all of SolrCloud's information inside a path in
zookeeper, sort of like a filesystem.  With no chroot, that information
is placed at the "root" of zookeeper.  If you want to use a zookeeper
ensemble for multiple applications, you're going to need a chroot.  Even
when multiple applications are not required, I recommend it to keep the
zookeeper root clean.

You can see some examples of zkHost values in the javadoc for SolrJ:
