Create IP address "127.0.0.1/8"
Assign 127.0.0.1/8 to VM interface "vm_int1"
Execute PATCH request to /api/virtualization/virtual-machines/ (Insert respective Ids of VM and IP):

curl -X PATCH \
      -H  "accept: application/json" -H  "Authorization: Token $NETBOX_TOKEN" \
      --data '{"primary_ip6": 1}' -H "Content-Type: application/json"

We may be able to reuse some of the validation that we have in place for this on the Device model, however that also checks for interfaces on virtual chassis members, which doesn't apply to virtual machines.
