Boot command not working #163
Description
Getting the following error when trying to build an image using a boot command
Error detecting local IP: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none], no supported methods remain
The actual failure here seems to be when packer tries to connect to the VM via SSH after the VNC connection, but this fails as the VM is still sitting at the install menu. No boot command or interaction is getting sent to the VM over the VNC connection as far as I am able to tell. The VM is only up for a few seconds before this failure tears it back down.
My assumption is that the VNC connection is getting established (as the logs indicate a 200 response to console connection request), but the boot command is failing to be sent and the packer process just moves on to the next step, where it fails to connect as it wasn't able to get far enough to get an IP address and initialize the VM.
Extra info
following the guide here: https://xcp-ng.org/blog/2024/02/22/using-packer-with-xcp-ng/
saw this issue with the exact setup described in the guide, and after various tweaks to try and get this working.
