I ran into a problem a short while ago with Landscape clients unable to connect to my Landscape server, and just recently figured out what’s going on. Essentially PyCurlError: Error 60: server certificate verification failed. I eventually found what the problem was, and hope to share it with you to save you time.
How subscribed is your server? Here’s a sample of top output. Here’s some key things that beginners need to know about how your host “sees” the VM’s. My example is KVM on LTS. This example is based on a dual proc xeon 8 cores, no hyperthreading, 64GB, HP Gen 5 Proliant Rack Server.
