Re: creating multiple VM's from template
Does Storpool have a native driver for Xenserver? If not and you use iSCSI then bad luck, Xenserver uses LVM for iSCSI storage pools and thin provisioning is NOT SUPPORTED there, so you are thick/full provisioning all your machines.. 50 machines x 100GB (I imagine) is a lot of storage traffic. Do you have to run this operation often?

Hi Jithin Thanks for the tip - I wasn’t aware of this setting. I checked the setting and it is set to false.
