When performing a vMotion, a warning like “No guest OS heartbeats are being received. Either the guest OS is not responding or VMware tools is not configured properly” can appear in vCenter.
This prevents VM migration and indicates that the VMware Tools are either not installed or are not running in the virtual machine.
As explained in the following vmware knowledge base article:
- Ensure that the VMware Tools are installed in the virtual machine before performing a migration.
Ensure that the virtual machine has been running long enough for the operating system to be completely started before performing a migration.
Restart the VMware Tools service. To restart the VMware Tools service:
Click Start > Run,type services.msc, and press OK.
Right-click VMware Tools Service and click Restart.
If the issue persists, reinstall VMware Tools to ensure that you are on the latest version.
