+The OpenNebula Environment Manager (oneenv) is a component to handle the
+deployment of interconnected multi-VM application services on top of the
+OpenNebula IaaS platform. It supports the automated creation and run-time
+scaling of multi-VM application environments. It leverages the OpenNebula
+contextualization framework to setup clusters of VMs in a master-slave
+configuration or a set of workers with an IP load-balancer in front. Policies
+can be defined to control how VMs are added or removed based on manual, time
+of day, or application load-based triggers.
+The system will ensure that an appropriate number of VMs are started even
+in the presence of hypervisor or data center failures to meet application
+service requirements. Environments can be aggregated so that multi-tier
+services consisting of web, app, caching, database clusters can be
+interconnected and deployed as unit. A variety of sample integrations with
+distributed middleware and tools like Tomcat, CloudFoundry, Jenkins, HBase
+are provided.
+For service developers, an IaaS platform and layered tools like this can help
+turn their applications from static, manually configured systems that take
+weeks or months to deploy and change into dynamic and adaptive systems.
+Infrastructure becomes just another set of APIs that you use in developing
+your service so that the infrastructure will scale as your service
+workload evolves.
+Key Features
+* Automated deployement of clustered services (load-balanced worker pool or master-slave deployment pattern)
+* Automated deployment of multiple inter-dependent clusters
+* Integration with Balance software load-balancer with open hooks to support other load-balancers
+* Auto-recreate VMs that disappear, fail or go into unknown state due to hypervisior or transient network/storage issues
+* Auto-scaling of environments based on time of day or day of week
+* Auto-scaling of environments based on load (cpu by default with support for custom metric plugins)
+* Prioritization of services and resource pools into 'gold','silver','bronze' classes.
+* Preemption and reclaim of resources from lower classes when higher priority classes required them
+* Active-Active and Active-Passive DR support where environments in surviving data centers are scaled up in response to datacenter outages
+* Centralized management and failover of the oneenv controller

+ -r, --remove STRING Remove environment and delete VMs
+ -u, --scaleup STRING Scale up environment by adding VM
