Network Quick Tasks

Use this page for fast network actions. For full context, use Network (Full Guide).

Task 1: Decide if You Need Changes

When to Use:

Use this before creating or editing any network object.

Purpose:

Confirm whether an existing guest network already meets workload needs.

Steps:

  1. Open Control Center -> Network -> Guest Network.

  2. Confirm at least one target guest network exists.

  3. Check network state and IP capacity for your target workload.

  4. Continue without changes if an existing network is already usable.

Expected Outcome:

  • You decide correctly whether to reuse an existing network or create new network resources.

If this fails:

  1. Refresh the Guest Network page and re-check state/capacity.

  2. Verify you are in the correct environment/zone context.

  3. Continue with Task 2 when no suitable network is available.

Task 2: Create a Basic Guest Network

When to Use:

Use this when no suitable guest network exists for the workload.

Purpose:

Create an isolated or shared guest network and make it available for VM provisioning.

Steps:

  1. Open Control Center -> Network -> Guest Network.

  2. Click + Add Guest Network.

  3. Select Isolated or Shared.

  4. If Isolated, fill required fields: Zone, Network Name, Network Offering.

  5. If Shared, fill required fields including VLAN, Gateway, Netmask, Start IP, and End IP.

  6. Save and verify the network appears in the table with a usable state.

Expected Outcome:

  • A new guest network is listed with the expected type and state.

  • VM provisioning can target the new network.

If this fails:

  1. Confirm required fields are complete and values are valid.

  2. Verify subnet/gateway/VLAN values do not overlap existing ranges.

  3. Retry from the create form after refreshing the page.

Task 3: Add Management, Storage, or Public IP Capacity

When to Use:

Use this when network operations fail because IP ranges are exhausted.

Purpose:

Expand available addressing capacity under the correct traffic type.

Steps:

  1. Open Control Center -> Network -> Physical Network.

  2. Open the target physical network and go to Traffic Types.

  3. Open Management, Storage, or Public based on capacity need.

  4. Add or expand the required IP range.

  5. Save and re-check available capacity.

Expected Outcome:

  • New range is visible in the selected traffic type.

  • Related create/provision actions no longer fail due to capacity.

If this fails:

  1. Verify gateway, netmask, start IP, and end IP are in the same subnet.

  2. Confirm the range does not overlap existing ranges.

  3. Check role permissions for range create/edit actions.

Task 4: Fast Triage for VM Has No IP

When to Use:

Use this when a VM is running but has no expected network connectivity or IP assignment.

Purpose:

Quickly isolate whether the issue is guest network state, IP capacity, or service dependency.

Steps:

  1. Confirm guest network state and IP range availability.

  2. Confirm isolated-network service dependencies are healthy (when using isolated networks).

  3. Validate VM-side network configuration from VM console.

  4. Correlate findings with Observability.

Expected Outcome:

  • You identify the most likely failure layer and next remediation path.

If this fails:

  1. Repeat checks once after a controlled refresh.

  2. Capture guest network state, VM identity, and alert evidence.

  3. Escalate when state remains stuck or recurring alerts continue.
