### Problem On VMware environments using the NSX integration, implementing a guest network can fail during `PlugNicCommand` even though `CreateNsxSegmentCommand` has already succeeded. The NSX segment is created outside vCenter. Its backing distributed virtual port group can therefore take a short time to become visible through the vCenter API. `HypervisorHostHelper.prepareNetwork` currently performs only one immediate lookup for NSX networks and returns failure when that first lookup is empty. Sanitized management-server sequence: ```text CreateNsxSegmentCommand ... NsxAnswer result=true Prepare network on vmwaredvs <redacted> Failed to create guest network <redacted> PlugNicAnswer result=false ``` The failure rolls back the NIC attachment and prevents the persistent VPC guest network from being implemented. ### Versions - Apache CloudStack 4.22.1.0 - VMware vSphere / vCenter 8.0.3 - CloudStack NSX integration ### Steps to reproduce 1. Configure a VMware zone with the CloudStack NSX integration. 2. Create an NSX-backed VPC guest network. 3. Allow the NSX segment command to complete while the backing DV port group is not yet visible through vCenter. 4. Observe the immediate DV port group lookup fail in `HypervisorHostHelper.prepareNetwork`, followed by a failed `PlugNicCommand`. ### Expected behavior After successful NSX segment creation, CloudStack should use its existing bounded DV port group readiness wait before attempting to attach the NIC. If the port group never becomes visible, the existing timeout should still fail the operation cleanly. ### Proposed fix Enable the existing `waitForDvPortGroupReady` path for NSX broadcast domains and add a regression test covering an empty first vCenter lookup followed by a successful lookup. -- This is an automated message from the Apache Git Service.
