Hi Team,
Could someone let me know the difference between creating VM from clone and template in oVirt? It really looks the same.
I think you can create a "clone based on template" (independent from template) or "thin machine" (dependent from template. if template breaks machine also breaks) ? How to "creating VM from clone" ? I'm also new to ovirt and investigating it. By the way, ovirt/redhat docs says: ------------------- When you create a template, you specify the format of the disk to be raw or QCOW2: QCOW2 disks are thin provisioned. Raw disks on file storage are thin provisioned. Raw disks on block storage are preallocated. ------------------- I have a hyperconverged install with glusterfs file storage, and when I create template, it is have a "allocation policy = thin provision" automatically. But when I create new machine without template, I can create new disk image and select allocation policy - thin or preallocated. Are there a way to create preallocated VMs from template and file storage? I think they will be more reliable/safe and error-prone?
