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 ...
Thanks,
Punit

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.
