vCLS virtual machine fails to power ON

Products

• VMware vCenter Server
• VMware vSphere ESXi

Issue/Introduction

Symptoms:

• Unable to power on the vCLS virtual machine.
• Only one vCLS virtual machine is deployed in the cluster.
• The following message appears in the eam.log and vpxd.log of the vCenter Server: "Feature 'bad_requirement:hv.capable' was 0, but must be at least 1."

Environment

VMware vCenter Server 7.0.x

VMware vCenter Server 8.0.x

VMware ESXI 7.0.x

VMware ESXI 8.0.x

 

Cause

If the "vhv.enable = true" parameter is set in the /etc/vmware/config file on the ESXi host, the system attempts to enable Intel VT-x/AMD-V when the vCLS virtual machine powers on. However, the vCLS virtual machine is not compatible with Intel VT-x/AMD-V, so it fails to power on.

Resolution

To resolve this issue, disable the vhv.enable setting on the ESXi host:

1. Place the target ESXi host in maintenance mode.
2. Connect to the ESXi host via SSH and log in as the root user.
3. Run "vi /etc/vmware/config" to open the configuration file.
4. Comment out (#) the vhv.enable setting.
   
   Before:
   vhv.enable = true
   
   After:
   #vhv.enable = true
   
   
5. Reboot the ESXi host.
6. Exit maintenance mode.

Note: If hardware virtualization is required for a specific virtual machine, please enable "Hardware Virtualization" (Expose hardware assisted virtualization to the guest OS) on a per-virtual machine basis while the virtual machine is powered off.
