Privilege: Access Virtual datacenters view |
| Excerpt |
|---|
The Virtual datacenters view is you can manage your compute, network and storage resources. Each virtual datacenter (VDC) is a separate cloud environment in a single datacenter or public cloud region. To access Virtual datacenters view, click the Basic virtual datacenters concepts |
Virtual appliances
...
A virtual appliance |
...
is like a folder that contains |
...
a group of one or more workloads (virtual machines (VMs) or containers) that may be related and can be used together to provide a service. Each VM is an independent entity but you can deploy all of the VMs in the virtual appliance together. |
...
You can manage virtual appliances in the Virtual datacenters view on the Virtual appliances tab of a virtual datacenter in either list view |
...
or card view. |
Virtual machine instances
...
An instance is a copy of the selected disks of a VM at a given time that is stored as a VM template. In private cloud with hypervisors, the platform saves the disks and a copy of the original template definition, unless the VM was captured from outside Abiquo, in which case it saves the configuration of the VM. The platform stores the instance under the master template in the Apps library. In public cloud, the platform saves the disks and the configuration of the VM as an independent template. Remember to enter a new name so you can identify the instance template. |

Virtual storage concepts
...
In Abiquo hard disks are the platform, hard disks are non-persistent and they are destroyed when deleted from the VMs or when the VMs are undeployed. In private cloud datacenters with hypervisors, the platform creates hard disks on the hypervisor datastore.
...
In Abiquo private cloud datacenters, volumes are persistent and independent of the VMs. The platform creates volumes on external storage devices. Volumes are available in private cloud datacenters with hypervisors and they require the external storage feature.
...
A persistent VM template has one or more persistent disks on external storage volumes. Persistent VM templates are available in private cloud datacenters with hypervisors and they require the external storage feature.
Persistent VM template disks are associated with a specific virtual datacenter. Hypervisors running persistent VMs will work directly from any persistent volumes. VM data stored on a persistent disk will be persisted on the external storage device. When you undeploy a VM, all changes made to the non-persistent disks will be lost. The next time you deploy the VM, the non-persistent template files will be freshly created, for example, standard template disks will be copied again from the appliance library to the target hypervisor. Note that it is not necessary for you to use a persistent disk as a system disk when you create a persistent VM.
