Try what Arik suggested: Open VM > Resource Allocation tab Set "Storage Allocation" to "Thin" This will create create an empty qcow2 image using the template disk as a backing file. No data will be copied when creating the VM. But note that this creates a dependency on the template. You will not be able to move the disk to another storage domain without copying the template to the other storage domain. This also creates a single point of failure - if the template become corrupted all the vm on top of it will break.

Hi, no, we don't use bit cloning via "clone" function, but we use templates as a raw format template. When creating a VM through this template, the server load will increase a lot. We want to minimize this sharp increase during the establishment. We are willing to wait longer to set up the server. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/UZNQMWBETBZNAV6I47EFE5W6ZB4TDUJR/
