It became quite a pain to get Web-based console working on ESXi hosts or vCenter servers with deprecation of NPAPI plugins in modern browsers. As for me, the most comfortable method to get a remote console access is to use standalone Virtual Machine Remote Console client (VMRC) which is available for free for major OSes. The sad part about VMRC is that you have to login to ESXi web client/vCenter, choose a desired VM and click on Launch VMRC link to get access. Too many unnecessary and annoying steps to take.
In my day to day work I have to deal with 2-4 VMs and what I want is to have their consoles 1-click away. In this post I’ll share a tiny Python script which composes links for VMs suitable for VMRC: vmrc://email@example.com:443/?moid=vm-373 . Click on the previous link will trigger VMRC to connect to virtual console of a VM.
