I guess it's the real value, right? The same happened for the memcached vm, someone reported to me - negative value in REST-API, but correct graph in oVirt webadmin GUI. I fear I have no idea how this can happen - so maybe someone else can help you troubleshoot this issue.

Do you have memcached running in this vm?
I heard about this issue with memcached, but never tested memcached in my oVirt environment. You get the real usage value with memory.used = memory.installed + memory.used
