Iam planning to install multiple instances in active/active cluster.Will
there be ant problem if I use the same name for virtual server and the
instance name ?Any disadvantages?

Thanks

The virtual server name must be unique on the network and the instance
name must be unique on the cluster.

What you would normally get on a cluster with multiple SQL instances is
each instance having its own unique virtual server name and its own
unique instance name (only 1 instance on a cluster can be the default
instance but I'd recommend making them all named instances for
consistency and to avoid confusion). Like:

Instance 1: VSQL1\Inst1
Instance 2: VSQL2\Inst2

or

Instance 1: SQL20\Production
Instance 2: SQL21\Test

or something similar.
