You don't need a new entity ID, and if you don't care about overrides, you
don't need them.  You'll need to add vhost ACS endpoints to your SP
metadata, however.  The IdP metadata wouldn't change, but it will, of
course, need the updated SP metadata.

This is discussed here:

If you take the example:
<md:AssertionConsumerService Location="
<https://service.example.org/Shibboleth.sso/SAML2/POST> index="1"
if you had a service2.example.org, you'd just need a second ACS with
<md:AssertionConsumerService Location="
<https://service.example.org/Shibboleth.sso/SAML2/POST> index="7"
