error using xscontainer-prepare-vm

[kifeo]

While following the procedure https://github.com/xcp-ng/xcp/wiki/Docker-in-XCP-ng, at the command xscontainer-prepare-vm -v <VM_UUID> -u <username> I got:

Traceback (most recent call last):
  File "/bin/xscontainer-prepare-vm", line 272, in <module>
    sys.exit(main())
  File "/bin/xscontainer-prepare-vm", line 246, in main
    resultcode = _handle_ssh(session, options)
  File "/bin/xscontainer-prepare-vm", line 139, in _handle_ssh
    resultcode = push_ssh_key(session, options.vmuuid, options.username)
  File "/bin/xscontainer-prepare-vm", line 80, in push_ssh_key
    print(docker.ERROR_CAUSE_NETWORK)
AttributeError: 'module' object has no attribute 'ERROR_CAUSE_NETWORK'

Hi, thanks for this report. From what I can see, it is an exception raised when trying to display an error message. So there was a real issue with your network configuration as seen from the xscontainer plugin, but it failed to display the error properly because it tried to print a non-existing attribute.

I'll report the bug about the failure to display the error message to the developers (Citrix developers), but I don't know what the root cause was exactly.

The function that failed first is this one: https://github.com/xenserver/xscontainer/blob/master/src/xscontainer/api_helper.py#L451. It seems that it's a function that is trying to get the VM IP. Were the xen guest tools installed in the VM? Had the VM an IP address?

Hello, Indeed I could test that with the xen guest tools it works, but generates the error if the tools are not installed. I added a line on the guide to correct this. (https://github.com/xcp-ng/xcp/wiki/Docker-in-XCP-ng) Thanks !

Thanks for the feedback and the update of the wiki. I'll keep this issue open to track the upstream bug.

I'm getting this error even with Management agent 8.1 installed on Ubuntu 20.04.2 LTS tho Any idea why? VM Does have an IP Address
