The VirtIO Balloon Driver is a driver used in virtualized environments (such as when running virtual machines on platforms like KVM/QEMU, Proxmox, or Xen). Its primary function is to dynamically manage memory allocation between the host system and the guest virtual machine. It enables efficient memory management by allowing the virtual machine (VM) to "balloon" or "release" memory, depending on the demand for resources.
