we are considering writing something like this, for virtual machines not
for baremetal. Our use case is that a project buying some compute
hardware is happy for others to use it, but when the compute "owner"
wants sole use of it, other projects' instances must be migrated off or
killed; a scheduler weigher like this might help us to minimise the
number of instances needing migration or termination at that point.
Would you be willing to share your source code please?
