Hi Itamar,
Thanks for the update....Yes.. 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.

Could you please more elaborate point number 3...how to use it..i will
go with this one ...

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.. ??
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.
Thanks,
Punit

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

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?
Thanks,
