OVF Import Failure Due to NSX Manager NIC Disconnection

Products

• VMware Cloud Director

Issue/Introduction

• When attempting to import an OVF in VMware Cloud Director, the process fails with a platform error reported from vCenter and ESXi.
• Hosts are unable to communicate, resulting in DRS imbalance and NSX resource contention.
• OVF import fails in VCD with a platform error.
• Host communication errors observed in logs.
• DRS is unable to rebalance workloads.
• NSX Managers are unreachable, affecting resource distribution and host to host networking.

Environment

• VMware Cloud Director 10.3
• vCenter & ESXi 7.0
• NSX 3.2

Cause

• The NICs on the NSX Manager VMs are disconnected, isolating the managers from the network.
• This prevents host to host communication, causing DRS failures and NSX resource constraints.

Resolution

• Reconnect the NICs on the NSX Manager VMs.
• Verify host communication is restored by initiating vMotion of a VM to another compute resource.
• Confirm that DRS rebalancing and NSX resource distribution are operating correctly.
