Root Cause

The root password is not set on IOx. This happens after loading a new image for IOS which loads the IOxVM image or just loading the IOxVM image.

Solution

Enable SSH and set the IOx root password:
IR809-DM-IOX#iox host exec "resetpw cisco" IR809-DM-IOX-GOS-1
IR809-DM-IOX#iox host exec "enablessh" IR809-DM-IOX-GOS-1
ssh enabled successfully.
