Unable to get VNC port

[wkoszek]

I've managed to install packer-builder-xenserver and I'd like to make my first VM on XenServer. However it looks like the packer is failing to setup the VNC connection appropriately. Has any of your encountered this problem before?

Debug mode enabled. Builds will not be parallelized.
xenserver-iso output will be in this color.

I'm investigating. I've run the builder with the env HTTP_PORT_MIN=5900 HTTP_PORT_MAX=5999 and there was no difference.

@wkoszek - any progress on this? I'm seeing the same behavior building an Ubuntu Bionic image on XenServer 7.2.

Edit: In my environment, it was due to using a non-local user for XenServer authentication. Since the builder establishes an SSH connection to the XenServer (in order to forward the VNC connection) you need a user that can login directly to the box running XenServer. I was trying to use a user that was configured in XenServer for LDAP login.

[wkoszek]

@jesseops So it works all right for you?

Personally after trying the ecosystem around xenserver I decided to switch away from it. I tried vagrant-xenserver, and I recall that didn't work. Then I tried fog-xenserver and that didn't work either...

I installed Vagrant on my server. Securing stuff correctly was two days of work, but I haven't had problems ever since.

[jesseops]

It does now, just needed a user that could SSH to the actual host running Xen. We're pretty heavily invested in Xen (to the tune of 4k VMs) so definitely happy I could get this builder working.

Hello @madwizard I tend to use the repository at : https://github.com/ctlam/packer-builder-xenserver. There is a fix for this issue in this repository. Hopefully that should get you unblocked.
You will need to build the plugins yourself from this repository before you can start making use of the fix.

Hope this helps.

I also wanted to mention that I've been developing a fork that fixes this issue as well (https://github.com/ddelnano/packer-builder-xenserver/). My fork also has pre-built binaries and uses the latest packer so it would be easy to get setup with.
