lincked and full clone of new instance VIO 3.0

[s4muz]

Hello

When i start a new instance from a previous created image, it's always a linked clone from the image on vcenter. Is this a correct behavior? Can i change this for a full clone of a new instance?

Thanks

The use_linked_clone boolean option (in the vmware section of nova.conf) determines this behavior.

Do you think that its a good practice to use linked clones? I mean for production environments.

It depends on your requirements. If most of the instances are created from a small set of images, the space saving due to linked clones will be significant. Also, if you need fast provisioning of instances, linked cloning can be considered. The full clone operations will be much slower for large size images. If read performance is important, you may want to disable linked cloning.

Isn't possible to have both, right? Like use metadata to define if i want full or linked option for the instance. My problem it's more related to performance than space saving.

Thanks v_bala
