1.2 Virtualization Features

Important Note Before moving to Cloud Features, it is important to understand that ConVirt Enterprise Cloud product includes all features of ConVirt Enterprise. ConVirt Enterprise has comprehensive features around managing heterogeneous virtualization platforms. To learn more, please visit ConVirt Enterprise Documentation

1.3 Cloud Features

1.3.1 Seamless virtualized-to-cloud conversion

Setting up a private cloud is easier with ConVirt Enterprise Cloud. In fact, if you already have virtualization deployed in your data center, you have all the technology you need to run a private cloud. With a few simple clicks you can designate which parts of your existing infrastructure (server pools, networks, storage, and templates) should be used for the cloud deployment and ConVirt Enterprise Coud will take care of everything else!

1.3.2 Third Party Cloud support

Public clouds provide a convenient way to quickly add capacity. However, that extra capacity often comes with extra management overhead, since you now need to track two separate deployments using different tools. ConVirt Enterprise Cloud enables you to integrate your Amazon EC2 account into your ConVirt console. Then, from within ConVirt, you can provision new virtual datacenters, manage virtual machines, configure security groups, and much more. This enables you to get a centralized view of your cloud resources and clients, irrespective of whether they are hosted in your data center or remotely.

In addition to Amazon EC2, ConVirt can also manage local cloud deployments of OpenStack and Eucalyptus using the EC2 compatible APIs. This way both public and private cloud deployments can be managed via a single ConVirt Console.

1.3.3 Virtual Data Centers

Virtual Data Centers enable you to provision new cloud clients within seconds.

  • Resource limiting
ConVirt Enterprise Cloud enables you to limit the compute, storage, and network resources that your cloud clients can use, ensuring that they do not go above the allocated quota. Clients can continuously monitor their resource consumption via the user console, making sure that they are not surprised when they run out of resources.
  • Delegated control
ConVirt Enterprise Cloud gives you full flexibility in choosing the extent of control you want to delegate to your clients. Whether you choose to pre-configure everything and give the client a view-only screen, or dedicate computing resources and let the client create, provision, and manage custom applications, ConVirt Enterprise Cloud has you covered.
  • Highly-interactive user console
Each client gets access to ConVirt’s highly interactive web-based user interface, where they can manage their virtual machines, templates, networks, and quota without having any visibility into the underlying physical infrastructure.


1.3.4 Multi-tenancy and Networking

ConVirt Enterprise Cloud delivers fine-grained, role-based access control, enabling you to share your infrastructure resources among multiple clients while ensuring full isolation.

  • Network isolation
By default, each client is assigned a separate VLAN in order to ensure full network isolation. Additionally, you can choose to allow clients to create a limited number of their own private networks.
  • Access to existing corporate networks
In cases where network isolation is not required, ConVirt Enterprise Cloud enables you to grant clients access to existing corporate networks.
  • Public IP Management
ConVirt Enterprise Cloud enables clients to optionally make their virtual machines accessible over the Internet by assigning a public IP address. You define a Public IP pool and assign Public IP quotas to Virtual Data Centers. Clients can then request a Public IP, assign it to a virtual machine, and release it back into the Public IP pool.

1.4 Virtualized-to-cloud conversion

Virtualized-to-cloud conversion involves preparing and selecting resources that would host the cloud. In ConVirt this is represented by IaaS ( Infrastructure as a Service ) entity. In the following section, we will go through this process in more detail.

1.4.1 Preparing for Cloud conversion

This section outlines the resources required for creating a cloud. If you are existing ConVirt user, then you will already have most of these things in place. You will have to deal with only a subset of these which are unique to cloud operations. Nevertheless, it might be a good idea to give this section a read.


1.4.1.1 Server Pools

In ConVirt, the compute resources are Servers running Xen/KVM/VMWare/Hyper-v virtualization. These are organized in Server Pools. In order to provide compute capacity for the cloud, you can select one or more server pools. The Virtual machines would be created on servers within this server pools.

Tip : If you are not familiar with Servers and Server Pools, please refer to ConVirt Enterprise Documentation .

For correct operations the server pools selected must meet following requisites.

  • Consistent Storage : The server pools should at least have one shared storage associated with them.
  • Consistent Networking : All servers within the server pools should be consistent in their network connectivity. for e.g. all servers in the selected pools has eth0/br0 as management interface and eth1 for creating VLAN interface.
  • High Availability : The high availability should be enabled for the server pool containing hosts. This is not a requirement however, where an external node is selected as Network Service Node.


1.4.1.2 Storage

The virtual machines disks would be created from the Storage defined and associated with the Server Pool. The storage should be attached with all server pools selected.

  • example : In this example, we will create a NFS storage and associate with Server Pools.
NFS Storage Associate with Pool(s)
Create nfs store.png Create nfs store sp.png

1.4.1.3 Networking

  • VLAN enabled infrastructure : You should have managed servers collected to a VLAN enabled switch, which is configured to carry VLAN tags on all ports (trunked). This is required as ConVirt creates a private network on separate VLAN.
  • Defined networks : Already defined networks can be made available to the Cloud. This greatly simplify the cases where certain Virtual Machines need to be created on one of these networks. For this, the network should be defined and attached to all the server pools selected.
    • example :
Corporate Network Attach to Server Pool(s) one by one
Create new saas nw.png Attach network to sp.png
  • VLAN ID Pool : ConVirt creates private virtual networks for isolation. One such network is typically created, each time a new cloud client/Virtual Data Center is provisioned. More over ConVirt has capability to allow the user to create its own private networks. ConVirt requires a VLAN id when such private network is to be created. For convenience, a VLAN ID Pool needs to be declared. The declaration of such pool has two components, the range of VLAN ids itself and IP Detals for each private network. ConVirt allows you to pick a network (in CIDR form) and subdivides it in to IP subnets, one for each vlan id.
    • example :
Create VLAN ID Pool Associate with Server Pool(s)'
Create vlan id pool.png Create vlan id pool sp.png
  • Public IP Pool : The virtual machines are typically created on a network that is private and are not accessible other than from other virtual machines on the same network withing a given Virtual Data Center. In order for these virtual machines to be accessible from the internet or a designated network, a set of external facing IP addresses are required. ConVirt allows creating a Public IP Pool to specify these addresses. One such pool can be specified while performing virtualized-to-cloud conversion. The Cloud clients will be able to reserve IP address and associate it with a Virtual Machine, to make it accessible from a designated public network (typically internet).
    • example :
Create Public IP Pool
Create vm public ips.png
  • Network Service : The above mentioned networking features are handled by Network Service within ConVirt. At least one host should be designated to run the Network Service. The Network Service host is typically connected to the following networks:
    • Management Network : This is the network ConVirt uses to configure/manage the Network Service
    • Private VLAN Network : This is the network that is partitioned for running virtual machines owned by different tenants/VDCs using VLAN
    • Public Network : This is a public/internet facing network. ConVirt will use the interface identified for this network for making virtual machines available on the public network.
ConVirt provides following two options for selecting host for running Network Service
  • Existing Managed Server : An existing managed server can be used as a network service host. While using this option, a primary and secondary network service host can be specified. When High availability feature is enabled for this server pool. ConVirt will switch over the networking service functions from primary node to the secondary node (and vice-a-versa).
Networking Service Host
Nw svc option 1.png
  • External Host : ConVirt also allows an external host designated as Network Service host. This host needs to be prepared in a similar fashion as "Managed Server" (including Xen or KVM virtualization platform). While running convirt-tool on this host, use --skip_bridge option as we do not need to create bridges on all interfaces. When this option is used, traditional Linux HA is recommended for the Network Service host.

1.4.1.4 Templates

An integral part of creating a cloud is to have a set of templates. You can use an existing template group or create a new one that holds the cloud specific templates. An important thing to note is that the storage used by the virtual machine is dictated by the template. You are required to keep the template and the storage associated with server pools consistent.

  • example :
Template General Settings Template Disk Settings and size
Template general.png Template storage disk size.png
Template Disks ISO Template Network Settings
Template storage disk.png Template networking.png

1.4.2 The Cloud conversion

To convert the virtualized infrastructure to a Cloud, an IaaS entity needs to be defined in ConVirt. We can do this using just a few clicks. While creating an IaaS, we will be selecting the following resources required to host a cloud.

  • Server Pools, that provided compute capacity
  • Network resources like Defined networks, VLAN ID Pool, Public IP Pools and Network service hosts.
  • Templates used for provisioning the Virtual Machines in the cloud

Lets go through a step by step flow to create one such IaaS.

Select the IaaS node in the navigator and use "Add IaaS" menu item.

Select "ConVirt" to create an IaaS from local infrastructure.


  • General Page : Provide a Name of the IaaS that you want to create here.

1.4.3 Using the Cloud

Once the Cloud is created, you can start provisioning clients. The clients gets to use the cloud capacity without knowing any details about physical infrastructure. In ConVirt, these clients are represented as Virtual Data Centers. While provisioning a new Virtual Data Center or VDC, you specify the resources that will be made available to it as well as the quota for each such resource.

ConVirt typically also creates a private network for each Virtual Data Center. Thus providing isolation across various clients.

Existing ConVirt users can be given access to the newly provisioned VDC or you can create new users and give them appropriate access. ConVirt comes with two Cloud roles, Operator and User. The Operator has access to all operations within a VDC, while the User role is given only do Start,Stop and Connect to existing Virtual Machines.


1.4.3.1 Provisioning Virtual Data Center

In this section, we will go step by step in Provisioning a new Virtual Data Center from 'MyCloud' IaaS that we created as a result of "virtualized-to-cloud" conversion.

  • Select IaaS : To initiate the flow, select the Virtual Data Centers node in the navigator and select "Provision Virtual Data Center" option. This will prompt you with a selection of available IaaS. Select the MyCloud that we just created. This will bring you to a new wizard where you can specify details about the new Virtual Data Center.

1.5 Third party Clouds

ConVirt Enterprise Cloud enables you to integrate your third party clouds into your ConVirt console. Then, from within ConVirt, you can provision new virtual datacenters, manage virtual machines, configure security groups, and much more.

ConVirt can manage Amazon EC2, OpenStack and Eucalyptus clouds using standard EC2 APIs. Managing these platforms via ConVirt has the following advantages.

  • Centralized View of virtualized infrastructure, private and public clouds.
  • Consistent access control across virtualization infrastructure as well as to third party clouds.
  • Limit access to subset of Regions, Templates etc provided by Cloud.
  • Provide resource quota management for Virtual Machines, Storage, Public IPs etc.


NOTE Currently ConVirt does not support Importing existing Virtual Machines in from third party clouds, this will be added very soon.

1.5.1 Declaring Amazon Cloud
