What is a OVF template?
What are the differen OVF templates?
The name of the manifest file ends in .mf and the file contains SHA-1 digests of the other files.
OVF descriptor
An XML document that contains information about the OVF template such as product details, virtual hardware, requirements, licensing, a full list of file references, and a description.
Virtual Hard Disk
The virtual hard disk file usually has a filename ending in .vmdk. The OVF specification supports multiple virtual hard disk formats, not just the VMDK files used by VMware vSphere.
What is a content library?
- Content Libraries are a way of storing VMware templates, OVF templates, ISO/FLP media files, orany file that you may want cataloged separate from your deployed VMs.
- They can be synchronized between vCenter Servers to allow a “publish once, consume elsewhere” scenario.
What are the ways to publisch a content library?
- Local – Stand Alone
- For local use only.
- No subscriptions or synchronization
- Local – Published
- The parent or source library.
- Subscribers get those changes based on their individual synchronization settings. CONTENT LIBRARIES
- Subscribed – Automatic
- Subscribed Content Libraries automatically download changes receive all content as soon as it is made available. The content includes all the metadata and the payload binary data.
- Subscribed – On Demand
- Only download metadata without any actual payload
What is VAPP resource allocation?
What is VAPP IP allocation?
The IP Allocation Scheme option allows you to modify how IP addresses will be allocated to child VMs.
