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) disk....it will
copy the whole 40GB to provision the virtual machine....so 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 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.. ??
Thanks,
Punit

ok...but how to move the data from the existing disk to new disk at the
time of the VM deployment... ?? is there any way to move the data.. ??
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

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?
Thanks,

deploy the new VM with this template,the process will copy the whole 16GB
or just 1 GB to create the new VM ??
