Shutdown command failed: remote command exited without exit status or exit signal

[va-h]

Hi,

I tried to create an Debian Stretch Config based upon the provided Centos Example, but no matter what I try packer doesn't seem to recognize the shutdown command.

I tried
/bin/sysctl poweroff
/sbin/shutdown -h now
/sbin/shutdown -P now
/sbin/halt

it doesn't make a difference. Except for /bin/sysctl poweroff which reduces the Log by following error

==> xenserver-iso: Unable to detach VDI 'ae55962b-0e2e-42c2-af3f-7f0cbde8803d': Could not find VBD for VDI 'OpaqueRef:cdb8d3c5-f016-6930-e953-e57eade7dd12'

which I guess is caused by already unmounting the iso when brought down with the other commands.

Log

xenserver-iso output will be in this color.
