You advise is appreciated.

Sorry I was trying to update my original post and delete it by mistake, so the reply is the original one.

The issue is also with vmware, not only happen with hyper-v

[Stuart Luscombe]

Did you find a solution to this issue?

I'm seeing the same thing when trying to build an RHEL 7 image. I can get the OS to install, but after the initial reboot nothing happens. The IP shown by packer will respond to a ping but trying to ssh into the box will not.

[Alvaro Miranda Aguilera]

Can you share your packer project somewhere?

kickstart + packer template + scripts that set the user you will be using on packer to ssh into

I didn't find a solution that time, so I built the server manually. but I think the issue was related to line feeds and boot command

Interestingly, I ran the example Ubuntu build from the hyperv-iso documentation page and apart from some minor adjustments to the boot_command it completes successfully.

I found that I needed to have an external VM switch created prior to running packer for it to work though.

With the RHEL build I can now SSH into the VM using the created packer account once the install has completed, but packer itself is still timing out waiting for an SSH connection.

OK, so I seem to have found the solution for my RHEL build issue.

Firstly, I needed to have an external VM switch already set up in Hyper-V as packer would only create an internal one. This would cause the build to fail as the VM could not get an IP address. Manually setting up an external switch resolved this problem and I was able to perform a full Ubuntu build as per the packer documentation.

Secondly it would appear that the RHEL-provided Hyper-V drivers do not work correctly. I installed the latest ones from Microsoft (https://www.microsoft.com/en-us/download/details.aspx?id=51612), rebooted and almost immediately packer was able to login and do what was needed.

Hopefully this info will help anyone else having the same problem.
