VDC management. OpenStack

The virtual data center service includes many objects:

• virtual machines (VMs);
• VM disks;
• routers; 
• networks; 
• load balancers. 

This article describes how to manage the data center, VDC virtual servers and hard disks. On managing networks, routers, and load balancers, see Network management.

Creating and stopping the VDC

BILLmanager automatically creates VDCs on the OpenStack side after the client has placed an order. Virtual servers are not created within the VDC. If the client has ordered several data centers through the billing system, these VDCs will be assigned to one account in OpenStack. 

Creating an VM

To add a virtual machine to the VDC, enter Products/Services → VDC → Virtual servers button → Create.

Specify the following parameters:

• Virtual server Name;
• Parameter set — a previously created set of resources. It determines the types of resources and their volume for the created VM.
  Sets are configured by the OpenStack administrator. These values are loaded into BILLmanager automatically when a service processing module is created and can be changed in Products → Product Types → VDC→ Options → Virtual server template → Values. In the figure above CPUs and RAM are defined by the selected set and are not available for editing;
• Operating system — an ISO image on the OpenStack side, from which an operating system will be installed on the VM. Available templates are loaded into BILLmanager automatically when a service processing module is created and can be changed under Products → Product types → VDC → Options → Operating system → Values;
• Network — the network to which the virtual server will be connected. If you add a VM to the VDC without a network configured, BILLmanager prompts you to add a network first;
• Create disk — option to automatically add a separate disk for the VM;
• Disk — the size of the disk to be created. The field is hidden if the Create disk option is inactive;
• Use oversold cores — an option to use CPU cores with overselling. If active, cores for VMs are allocated from the hypervisor group that is specified in the service processing module settings. 
• Password.

Creating and connecting disks

To add a hard drive to the VDC, enter Products/Services → VDC → Disks button → Create.

Specify the following parameters:

• Disk name;
• Type — the type of disk to be added. The types available in OpenStack are loaded into BILLmanager automatically when a service processing module is created and can be changed under Products → Product types → VDC → Options → Disk type → Values;
• Source — how the disk is connected. Available values:
  • Empty storage — a disk without any information on it is connected to the VM;
  • Image — a disk created based on the selected ISO image is connected to the VM;
  • Snapshot — a disk recovered from the specified snapshot is connected to the VM. 
• Disc size. 

You can create snapshots for each added disk. Enter Products/Services → VDC → select the VDC → Disks button → select the disk → Disk snapshots button → Create.

After creating the disks, connect them to the virtual servers under Products/Services → VDC → select the VDC → Virtual servers button → Disks button → Connect. If at the moment of connection there are no free disks in the system, BILLmanager will offer to add a new disk.
