Proxmox shuts down the VM when there is not enough memory.

Proxmos shuts down the VM when there is not enough memory.
The situations were created by 15 VMs.
They used up all the server's memory.
VM in HA on two nodes.
The node starts shutting down the VM.
How to organize, so that migration would occur with a lack of resources or some other solution.
Thanks

They used up all the server's memory.

Why is that?

The system protects itself from an out of memory condition. So this is fair from my perspective.

Their seems to be no automatic loadbalancing in PVE yet.
Check if this helps you:

Why is that?

When the node has 64G RAM.
When 20 virtual machines are created, and each allocated 4G RAM. All reserved memory 80G
And if you turn on everything at once, then some randomly turn off.
And I would like the node to warn and, for example, migrate the VM to another node.

Ah okay. That is - as @apoc already wrote - currently not possible. Best to not overprovison your host.
