This ansible task fails:

Describe the results you expected:
This should not have failed. The DUT does in fact have this file.

Additional information you deem important:
Further debugging revealed these values:
dut_name=vlab-01 and hwsku=Force10-S6000.
caglab@cag-rtp-ucs1-sonic:~/sim/sonic-mgmt/ansible$ cat /tmp/dbg.log
Platform type is x86_64-kvm_x86_64-r0
Port config file is /usr/share/sonic/device/x86_64-kvm_x86_64-r0/Force10-S6000/port_config.ini
get_portmap from file /usr/share/sonic/device/x86_64-kvm_x86_64-r0/Force10-S6000/port_config.ini

It appears we are running this task on the host server when it should actually be run on the DUT.
I was able to work around the issue by editing this task from roles/vm_set/tasks/start_sonic_vm.yml— --- a/ansible/roles/vm_set/tasks/start_sonic_vm.yml
