There are many virtual machines in my PVE. In order to save resources, I want to set some virtual machines as timed on / off machines. I can find a way to turn off the machine, but I don't know what to do when I turn on the machine automatically? My current version is the latest 6.2. I want to enter the BIOS setting in the virtual machine, and there is no way to enter.
How to make the virtual machine in PvE start regularly
- Thread starter cdyehl
- Start date
Why do you want to do that? To set when to start the VM? This will not work.
You can start a VM via the API [0] or CLI tools [1]. Cron jobs or systemd timers are two ways to trigger a start that come to my mind.

Many virtual machine systems are installed under my PVE. If they are always on, they take up a lot of resources. If you open them at the same time, the server crashes. So I want to turn some virtual machines on and off at different times, let them do something, and then turn them off automatically. In this way, system resources can be saved and the whole resources can be maximized.

It is not possible for the BIOS to power on a stopped VM. That functionality on a real PC depends on the BIOS clock running when the power is off due to the CMOS battery. There is no "CMOS battery" equivalent function in Proxmox VM's. When it is off it is off and nothing runs.
You can put a a cron job in /etc/cron.d to start and stop VM's using the command line. That's how you can accomplish what you want. See the second link in @aaron post above.
