Re: [ovirt-users] VM Deployment By Template

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..." Or it's different then the upper one...please let me know how to perform this...if any screen shot you can provide for better understanding..

I want the way i can make the template with small size....and 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.. ?? so you want to provision a VM with a different disk size than template. good point. some thoughts: 1. for thinly provisioned (qcow2) - its COW, hence the same size. 2. for clone - actually, no reason shouldn't be supported easily. 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, You would have to do that inside the guest…the same way as you would do it on real hardware…mount both disks, move the relevant data not trivial and not automated > > Another question is there any way to mount the img like i will create the VM with blank template with my preferred disk size and leter on install the OS through any OS template ??? i know i can install the OS through CD-ISO but i don't want the manual installation… so you want to have a preinstalled OS…so how did you want to use it? I probably don't understand what are you trying to achieve. Anything else than having a Template with OS and you deploy VMs from that….you need to change disk sizes for each such VM? Could it be done by adding an additional disk?
