Why not simply have the guest fill in the unused fields with -1, and
say that's how "no meaningfu

say that's how "no meaningful value" is represented in t
Changes since V1:
- In the monitor, print all stats on one line with less abbreviated names

When using ballooning to manage overcommitted memory on a host, a system for
guests to communicate their memory usage to the host can provide information
that will minimize the impact
