Re: [Users] Thin Provisioning

Can you please tell me what disk type you have on the template and send a screen shot of the Resource Allocation tab to the users@ovirt.org list? On 02/21/2013 09:43 AM, Juan Jose wrote:

when you open the new vm dialogue, after you select the template, in the Resource allocation tab you need to select the clone radio button (its near the Template Provisioning). once you do that, the allocation policy scroll will become active and you will be able to select thin or preallocated.
let me know if after you select the clone you still only have preallocated.

Hi Juan, I see what the issue is and it's actually by design. The template you created has a Preallocated image. in NFS, to make a preallocated image we actually write to the disk to make it preallocated. as you can see, I created a vm with preallocated disk in NFS and if I run DU during the creation of the image you can see the size go up: 2.4G . [root@orion f1a6a2e7-38f1-4a7c-8f3b-efbca664d7aa]# du -h 2.5G . [root@orion f1a6a2e7-38f1-4a7c-8f3b-efbca664d7aa]# du -h 2.6G . [root@orion f1a6a2e7-38f1-4a7c-8f3b-efbca664d7aa]# so in NFS storage, if your template is preallocated you cannot create a thin provision copy vm (distinguishing between the actual data and previously zeroed will be complicated). you can create a snapshot of that image which will be thin provision but it will be linked to the template. or you can create a thin provision template and than create a thin provision vm or preallocated vm.

Many thanks for your information Dafna. Quick Start Guide doesn't explain nothing about this and I have follewed it to create the two VM, Fedora 17 and Windows 7, that I'm using to create Templates and when I have arrived to this part I have found this problem. Now I know what is the procedure Juanjo. On Thu, Feb 21, 2013 at 2:25 PM, Dafna Ron <dron@redhat.com> wrote:

that's good input, I will look at the guide. thanks On 02/21/2013 06:00 PM, Juan Jose wrote:
