VMware vSphere ESXi

Issue/Introduction

Virtual machines hosted on ESXi nodes may surface optimization alerts stating that a virtual hardware upgrade is required. Running an outdated virtual hardware layer or obsolete VMware Tools package prevents the virtual machine from leveraging modern performance enhancements, advanced adapter features, and core stability features provided by newer platform branches, occasionally resulting in guest management monitoring instability or intermittent guest-to-host communication drops.

Diagnostic indicators within hostd.log:

Upgrade is required for virtual machine, version: <VERSION>

Diagnostic indicators within guest management subroutines:

VMware Tools (version=<VERSION>) not running; Setting heartbeat to red
Turning off heartbeat checker
guest operations are ready ... toolsRunning=true
Updating current heartbeatStatus: red -> green

Environment

  • VMware vSphere ESX
  • VMware vCenter Server

Cause

 

  • The virtual machine executes on legacy Virtual Hardware Version 9, generating compatibility disparities with the ESXi 8.0.3 execution line.

  • The guest operating system runs an outdated VMware Tools deployment (version 10346), driving heartbeat signal dropouts, management tracking timeouts, and virtual network driver instability.

 

 

Resolution

Part I: Verify VASA Provider Operational Status

Before initiating infrastructure remediation, confirm storage subcomponent stability to prevent storage path drops during VM power cycles.

  1. Log in to the vSphere Client.

  2. Navigate to the vCenter Server object in the inventory tree.

  3. Select the Configure tab, expand Storage Providers, and locate the VASA Providers list.

  4. Verify that the status of all registered VASA Providers reflects as Online and Active.

  5. If a provider shows a disconnected status, select it and execute a Rescan or Reconnect sequence before proceeding to VM maintenance.

 

Part II: Upgrade VMware Tools

Upgrade the guest driver stack prior to modifying virtual hardware layers.

Method A: Interactive or Automatic Live Upgrade (VM Running)

  1. In the vCenter Server inventory, right-click the target virtual machine.

  2. Navigate to Guest OS > Upgrade VMware Tools.

  3. Select the preferred installation type:

    • Automatic Upgrade: Executes a silent deployment inside the Linux guest execution frame without manual installer interaction.

    • Interactive Upgrade: Mounts the VMware Tools installer ISO to the virtual optical drive, allowing manual compilation/configuration within the guest shell.

Method B: Automated Upgrade via Cold Boot Sequence

  1. Right-click the virtual machine in the inventory window and select Edit Settings.

  2. Select the VM Options tab and expand the VMware Tools drop-down menu.

  3. Check the option checkbox for Check and upgrade VMware Tools before each power on.

  4. Click OK. The guest agent suite will validate and upgrade to match the ESXi host locker binaries during the next host reboot cycle.


Part III: Upgrade Virtual Machine Hardware Compatibility

  1. Schedule Maintenance Frame: Coordinate an operational window; this process requires the target virtual machine to be powered down.

  2. Generate Protection State: Create a virtual machine snapshot or full backup archive. Compatibility upgrades are irreversible modifications to the virtual hardware configuration file (.vmx).

  3. Power Off the VM: Right-click the virtual machine object, select Power, and choose Shut Down Guest OS.

  4. Apply Compatibility Step: Right-click the powered-off virtual machine, navigate to Compatibility, and select Upgrade VM Compatibility.

  5. Set Configuration Target: Choose the target host compatibility matching ESXi 8.0.3 and later and click OK.

  6. Execution Validation: Confirm the updated hardware version status displays accurately under the VM Summary panel configuration fields.

  7. Restore Power: Select Power > Power On to resume regular execution.
