Cause

SSH access from the Instance Manager (IM) node to the corresponding hardware virtualization node (HW node) by password does not work. In the PACI-vm2vf.log log file it is seen that IM tries to download package.zip from the OA Management Node:

Note that HW nodes should be accessible from the IM node with a password. If login with password is restricted (e.g. only ssh via public key is available), provisioning will fail.

Resolution

Fix the issue with SSH access to the HW node and resubmit the task to provisioning.
