IPv6 address can't be specified when attaching a NIC to a VM

[brodriguez-opennebula]

Description

Attaching an IPv6 alias on a VM specifying an address does not work. This does not happen when the IPv6 is not specified

To Reproduce

• Define an IPv6 range for a Virtual network

AR=[
  IP6="2a04:daaa:0:1::2",
  PREFIX_LENGTH="64",
  SIZE="256",
  SLAAC="off",
  TYPE="IP6_STATIC",
]

• Try to attach it (as an alias) to a VM

$ onevm nic-attach -n 33 -a NIC0 -i 2a04:da00:0:1::fff1 118
[one.vm.attachnic] Cannot get IP/MAC lease from virtual network 33.

• The template generated by the command would be the following

NIC_ALIAS = [ PARENT = NIC0, NETWORK_ID = 33, IP   = 2a04:da00:0:1::fff1]

Expected behavior The specified NIC would get an alias with the specified IPv6 address

Details

• Affected Component: Core
• Hypervisor: KVM
• Version: 6.8

Additional context

• As commented before, the following command works correctly and attaches an IPv6 alias on the interface

$ onevm nic-attach -n 33 -a NIC0 118

• IPv6 address ranges can be larger than the amount of MACs that can be assigned to its VMs. That can lead to a source of problems
