I have renamed a network and got error when instantinate VM:
[one.template.instantiate] Error allocating a new virtual machine template. User 2 does not own a network with name: DC-782-MyPayments . Set NETWORK_UNAME or NETWORK_UID of owner in NIC.
Next I changed templates that uses this network (remove NIC with old-name, and add NIC with new name). All started work fine!
I think it’s a good idea to use ID’s in templates? (for future releases)
