Causa
The Target Virtual Machine configuration file (.VMX) has the following entry:
isolation.tools.setinfo.disable = "TRUE"
This optional security settings will prevent the informational messages from being sent to ESXi. When this feature is true the vm ip address, hostname will not be visible in vSphere client despite vm tools showing running with a vaild tool version .
For more info see this page:
The VMware Tools setinfo variable is enabled for virtual machines. (stigviewer.com)
With this security setting the Avamar FLR code will not be able to read the varibile guestOS family. Additionally for faster FLR performance FLR code needs to obtain the VM Guest IP address which will be impossible with this security feature enabled.

Risoluzione
To confirm the entry exists in the target VM .VMX:
1. Login to VirtualCenter with the VI Client and select a virtual machine from the inventory panel.
The configuration page for the virtual machine appears with the Summary tab displayed.
3. Click Options > Advanced > Configuration Parameters to open the Configuration Parameters dialog box.
4. The result should appear as follows:
isolation.tools.setinfo.disable true
5. Change the "isolation.tools.setinfo.disable" = from true to false.
6. Reload or vmotion the VM so the change takes effect.
7. Do the FLR again.
Workaround:
Perform an FLR using a different target virtual machine that does NOT have the same optional security setting.
