Why do not all virtual machines turn on after a power outage at startup?

Question

VMware

We serve objects remotely, we have to come to turn it on manually, I checked the autostrat in the manage all-inclusive option.
1. Once a month, approximately after a power failure, not all virtual machines start up. How can this be fixed?
2. Once, after a power outage, two out of three VMs disappeared. I had to create machines and specify a disk image. Everything worked. It was the first time in five years that this happened. Nobody has access. We only have passwords.

Answer 1

you need to go to the server via ssh and see what is written in the autostart config . May need to be corrected
