Hi, this is my first question, so:
I’m playing with python sdk and i can manage the CRUD and some other options, but im stuck
in this one, when I create a VM from template this new machine is created in the same
storage than template is. If i want to move the machine I create it, wait to reach down
status and then, move their disks to a new storage. What I want is create a new machine
from scratch on a new storage.

name=vm_name,
memory=1*GB,
cluster=cnn.clusters.get(cluster_name),
template=cnn.templates.get(create_from),
disks=params.Disks(clone=True))

############################ WHAT I WANT IS SOMETHING LIKE THIS
discos = params.Disks()
for index, tmp_disk in enumerate(template.disks.list()):
disk = params.Disk(
name = "{0}_{1}".format(vm_name, (index+1)),
storage_domains=params.StorageDomains(
storage_domain = [api.storagedomains.get(sd.name)]
),
)
discos.add_disk(disk)
vm_created_dos = cnn.vms.add(params.VM(
name=vm_name,
memory=1*GB,
cluster=cnn.clusters.get(cluster_name),
template=cnn.templates.get(create_from),
disks=discos
)
)
Thank you all from Perú!!
