Instances in Virtual SQL Servers

Can someone explain setting up instances in virtual SQL Servers? I know that you can have multiple virtual SQL Servers on a cluster, but does each default instance, or is it one default instance on the cluster no matter how many virtual servers you have?
Thank you.
On a cluster you get one default instance and 15 named instances OR 16 named
instances. Of course you don't have to create all the instances, these are
just maximum numbers. The number of hosts in the cluster doesn't matter
towards the instance count.

|||Thank you. I was confused in that I thought each virtual machine would have its own default instance.

|||Each Virtual Server gets a single instance. It can be either a named
instance or a default instance, however only one such virtual server per
cluster can hold a default instance. This is because of how SQL stores the
binaries for each instance locally on each host node.
