(Doc ID 1525019.1)

Last updated on APRIL 01, 2018

Applies to:

Oracle Virtual Desktop Infrastructure - Version 3.3 and later
Information in this document applies to any platform.


While trying to clone new or recycle Desktops provisioned by VirtualBox within Oracle's Virtual Desktop Infrastructure (VDI), the VDI Administrator may notice that the cloning fails with the following exception:

Exception creating clone: Process cmdlines.bat failed with error '[Error=error_host_unreachable]...

 Meanwhile, the cacao logs would show that VDI is having a problem talking to the VirtualBox Webservice (running on host named 'host1.domain' as in below example):
