In some cases the worker func running inside the pool may rely on virIdentity. While worker func could check for identity and set one it is not optimal - it may not have access to the identity of the thread creating the pool and thus would have to call virIdentityGetSystem(). Allow passing identity when creating the pool. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Daniel P. Berrangé <berrange@redhat.com>
