Many software vendors already offer pre-configured OVA / OVF containers that you can upload and use without installing an operating system. Similarly, existing virtual machines can be exported to the same OVA / OVF format on both VMware and Citrix XenServer platforms.
In VVMware vCloud system you can create your own ISO and OVA/OVF catalogs, to use when creating virtual machines or later to add as a CD drive.
To create a virtual machine from an OVA / OVF file, you need to go to "Data Centers -> Compute -> vApps -> Add vApp from OVF".
Select Source/Review Details
A window will open. Under "Select Source", an OVA / OVF file must be uploaded from the computer, from which a virtual machine (VM) can be created.
Select the appropriate file and press "Open". Then "Next".
Opens "Review Details" with OVF template information. If the data is correct, click "Next".
Select vApp Name
Choose a name for the vApp and you can write additional information under "Description" to make it easier to distinguish between vApps later.
Select "Storage Policy", ie the storage to which the VM will be created. If you have a larger datacenter, we recommend scattering the VM´s between different storages to increase theoretical availability.
By default, the first IP on the network is automatically assigned.
By selecting “Switch to the advanced networking workflow” it is possible to set the network adapter type (it is recommended to use the VMXNET3 adapter, which is also the default setting). We recommend that you select “IP Pool” and the VM is given the first free IP out of the IP range assigned to you. You can also select “Manual IP” and set it yourself. In both cases, the automation configures the network settings in the template operating system, and the network is operational when the machine starts. If you select DHCP, the DHCP service must be set up in advance, otherwise the VM network will not start. Can be used, for example, for an isolated network, which must be defined in advance under "Networking -> Networks". If you select “Internet” or “Public” under “Network”, then there is no DHCP support. If there is a routed network, DHCP must be configured in “Data Centers -> Networking -> Edge Gateways”. We don´t recommend using DHCP.
Select the amount of CPUs and memory, but do not exceed the limit of ordered resources. Otherwise, the VM will not start. Everything can be changed later.
The CPU cores and memory can also be added to a running VM. We recommend disabling the hot-add later on the VM, if you want faster performance, on average the hot-add reduces the CPU performance by 7% because all the CPU commands can´t be used. We recommend keeping the memory hot add feature enabled.
Ready to Complete
Finally, you will see a summary before creating the vApp and the VM.
If everything is as desired, press “Finish”. The window closes. A vApp and a VM with the appropriate configuration are created.
Under “Data Centers -> Virtual machines” you will see a new VM. Click on "Actions" of the newly created VM, select "Power" and press "Power On".
The VM is then ready for use. Once the VM is turned on, you can open the console by clicking the VM Console button (All Actions -> VM Console -> Launch Web Console) and start configuring the VM through the console.
NB! Don't forget to install "VMware Tools" (Actions -> Install VMware Tools).
