When setting up a bare metal Proxmox machine with say 32Gbyte of RAM it seems to default to 32Gbyte of SWAP. When Proxmox runs low on physical RAM will it use its SWAP to keep VM's running? Would it make sense to increase swap farther too like 128Gbyte if think you might have a large number of VM's that use RAM but are mostly idle? Talking mostly OpenVZ VM's.
