Description of Issue/Question

Setup

As per the comment here, the name passed to the virConnectOpen should be stripped of port names.

// According to https://libvirt.org/uri.html
// The name passed to the remote virConnectOpen function is formed by removing
// transport, hostname, port number, username and extra parameters from the remote URI
// unless the name option is specified.

However, it seems specifying a port name does not correctly do this. This bug is subtle, however adding a test scenario reveals its presence. It also affects ssh-config based settings (specifically #1116) because the server name becomes incorrectly parsed as the string "servername:port" instead of "servername", causing the ssh_config to fail loading specific settings.

This code affects this call. However, I do not know how it affects the operation of virConnectOpen itself.
