Punit, What file system is your VM's partition, what operating system and version ? A question to others, if the doco says we support disk resize since 3.4, for what virtual disk type, and which operating systems and their partition types are supported by this. I would have believed you would needed to have used LVM and then add the new disk space as a new LUN, and map the new lun, while also using a file system that allows for expansion.

Re: [ovirt-users] VM Deployment By Template
Hi Sven, It's Ok...but still the drawback is if i have 100GB template and use clone instead of thinnow if i want to create 10 VM with this template...it will copy 1TB data...and the provisioning will take long time ?? Is there any other work around to make this copy partial or the ovirt just copy the actual used data at the time VM deployment instead of the whole virtual disk Otherwise it's very hard to use Ovirt as public cloud...because if every time it copy the whole template...and simultaneous more then 10 process running for the VM deployment all the process will stuck.. Another way i got is create the VM with 1GB virtual template and expand the disk size after deployment...but the problem here is disk will expand...but it will not done any changes in the existing partition table..that means after expand disk you need to manual login in to server and make the changes with the help of fdisk and lvm commands...

Clone in your case I believe would create a 40GB image file based on the template whereas thin provision will create you a thin provisioned disk just using the same actual data amount as the thin provisioned template. If you have a thin template and create a new vm using the option: clone what ovirt does is copy the thin template to a new disk. when you use thin ovirt does not create a new disk for the vm, instead the new vm shares the thin disk with the template (same file!) and creates another file just for the differences between template and vm, which accumulate over time. notice that you can not delete a template which has thin provisioned vms depending on it unless you delete all those vms.

Hi Itamar, Thanks for the updateYes.. i want to create different size VM with the same OS template... 3. we support disk resize since 3.4 (iirc), which you can do post VM provisioning. considering #3, then #1 should be easy to support as well these days. please open an RFE.

Hi Itamar, To edit the disk size are you referring this Another way i got is create the VM with 1GB virtual template and expand the disk size after deployment...but the problem here is disk will expand...but it will not done any changes in the existing partition table..that means after expand disk you need to manual login in to server and make the changes with the help of fdisk and lvm commands...

Re: [ovirt-users] VM Deployment By Template
Hi Michal, I want to deploy the VM with the template but the problem is in ovirt when you deploy the VM by template it copy the whole image(even thin or thick disk)...like if i have 40GB virtual size (actual size 1GB) diskit will copy the whole 40GB to provision the virtual machineso if i want to deploy 10 VM simultaneous then it will copy 4TB data and take long time to provision I want the way i can make the template with small sizeand once i choose to create the virtual machine with 40GB...the VM deploy with the small template on the 40GB disk... is it possible with ovirt.. ??

Re: [ovirt-users] VM Deployment By Template
So you essentially want to just deploy a new VM based on a template with a thin provisioned disk ? When you create your VM based on the template check in advanced options – Resource allocation and see if the option there for template provisioning is set to clone or to thin provision. Clone in your case I believe would create a 40GB image file based on the template whereas thin provision will create you a thin provisioned disk just using the same actual data amount as the thin provisioned template. I’m pretty sure you can only do this if your template disk is thin (not preallocated) provisioned.

Re: [ovirt-users] VM Deployment By Template
Hi Darren, Is it possible to change the Storage Allocation policy by cloud-init ?? as i want to deploy every VM with thin provisioning...i think the default method for the Template Provisioning is clone...
