# If enabled, the runtime will attempt to determine appropriate sandbox size (memory, CPU) before booting the virtual machine. In
# this case, the runtime will not dynamically update the amount of memory and CPU in the virtual machine. This is generally helpful
# when a hardware architecture or hypervisor solutions is utilized which does not support CPU and/or memory hotplug.
# Compatibility for determining appropriate sandbox (VM) size:
# - When running with pods, sandbox sizing information will only be available if using Kubernetes >= 1.23 and containerd >= 1.6. CRI-O
# does not yet support sandbox sizing annotations.
# - When running single containers using a tool like ctr, container sizing information will be available.
