NSX 4.2.4 appliances require the RDSEED CPU instruction set to function. If this feature is missing from the underlying physical server's hardware or is masked by a legacy vSphere Enhanced vMotion Capability (EVC) cluster baseline, the appliance cannot boot properly. This issue can impact upgrade and install.
This issue occurs when NSX appliances run on vSphere clusters which match the following criteria:
1. Unsupported VMware EVC Baseline Configurations
Intel CPU Mode: Intel "Haswell" Generation (L6) or earlier.
AMD CPU Mode: AMD Opteron™ "Steamroller" Generation (B3) or earlier
or
2. Unsupported Server CPU Series (with EVC Disabled)
Intel "Haswell" (or earlier) processors.
AMD Opteron™ "Steamroller" (or earlier) processors
This is a known issue impacting VMware NSX 4.2.4.
Remediation options:
Option 1: For EVC clusters configured with an unsupported mode.
Update the vSphere cluster EVC settings from the unsupported modes listed above to a supported, newer CPU mode. See Resolution section of KB#318962.
or
Option 2: For unsupported CPU hardware
If the NSX appliances are hosted on older physical servers with EVC disabled, migrate the VMs to a supported hardware generation CPU.
or
Option 3: If the recommended resolutions above cannot be implemented
On vSphere 8.0 or later - configure NSX-T appliance to use entropy from ESXi host (configure an External Entropy Source).
Reference: Configure an External Entropy Source
1. Log in to vCenter Server from vSphere Client.
2. Browse to the NSX Appliance VM.
3. Shut down the VM.
4. Right-click the VM and click Edit Settings.
5. Select Advanced Parameters.
6. Set/Add the isolation.tools.getEntropy.disable parameter to FALSE.
7. Click OK.
8. Reboot / power-on appliance
9. Resume installation/upgrade
