First VM 1: create a network

Start by creating a project network. The VM will attach to this network, and the router will give the network a path to the public gateway used for floating IP access.

Before you start

Confirm that you are in the correct Skyline project. Networks, subnets, routers, and floating IPs are project resources.

You will create:

• One project network.
• One subnet on that network.
• One router attached to the subnet.
• An external gateway on that router using the public gateway.

For a deeper explanation of these resources, see Networks and routers.

Create the network and subnet

1. Open Network, then Networks.
2. Click Create Network.
3. If Skyline shows a Quick Create option, use it for a first VM.
4. Choose a network name, such as first-vm-net.
5. Create a subnet at the same time.
6. For the default path, let the cloud choose the subnet values.
7. If you customize the subnet, choose a private CIDR that does not overlap with your other project networks.
8. Keep DHCP enabled unless you have a specific reason to manage addresses yourself.

Official Skyline documentation notes that a network without a subnet cannot be attached to an instance. It also lists the subnet fields Skyline can expose, including CIDR, IP version, gateway IP, DHCP, allocation pools, DNS, and host routes.

Create and attach a router

If the Quick Create form includes Create and Attach Router, check it. This should create a router and connect your new subnet to it.

If your project already has a suitable router, you can use that router instead. The router must have:

• An interface connected to your new subnet.
• An external gateway configured.

If you need to create the router manually:

1. Open Network, then Routers.
2. Click Create Router.
3. Enter a router name, such as first-vm-router.
4. Check External Gateway.
5. Select the public gateway.
6. Create the router.
7. From the router row, open More, then connect the subnet you created.

Skyline's official router workflow uses Network, Routers, Create Router, External Gateway, and then More, connect Subnet to connect a private network to the router.

Confirm the topology

Open Network, then Topology if it is available. You should see:

• Your project network.
• Your subnet.
• A router connected to the subnet.
• The router connected to the public gateway.

If the router or external gateway is missing, fix that before launching the VM. The VM can still boot without it, but floating IP and edge access will not work correctly.
