VM Pause state

[YOsip]

I saw that a VM can enter the "pause" state during "suspend mode backup job" and when the disk is full, how about running out of RAM? I'm implementing an API wrapper to Proxmox, specifically the reset function, and if the pause state could be an indication of RAM running low (which a reboot could solve at least temporarily) I will add it to the logic
(pausing when disk is full:

Not sure how that would work. But if you need it, you could implement yourself. Our code is on https://git.proxmox.com/

@Matthias. thank you for the replay, but I think you misunderstood my question. I wanted to know in what cases can a VM spontaneously enter a Paused state. Can it happen if a VM runs out of RAM? are there other cases?

 

[Matthias.]

Right, sorry, I did misunderstand you. No, not that I'm aware. If the VM runs out of RAM, the VM will deal with it, if the host runs out of RAM, the host will deal with it. Usually the OOM killer will do some killing, but that depends on your configuration.

@Matthias. Thank you for the quick answer
