I recently updated my Ubuntu install from 17.04 to 17.10, which meant the kernel was updated to 4.13. As a result, I was no longer able to run VMs with VMware Workstation. I found some posts regarding the error and that it was due to a change in the way the Linux kernel handles paging. To resolve the issue I needed to replace the vmmon modules. I didn';t take down the entire error message, but this post references the same error.
Recently I set about installing RancherOS. This was just to have a look and see what use cases it might help with. I chose to install RancherOS to a VM. In my case, VMware workstation. A roadblock I hit was providing an SSH key to the cloud-config.yml file. The roadblock specifically, how can I send a file to a system I don';t have a password or SSH key for? This article covers, generating an SSH key, SSH access to live CD and installation to hard disk.
