In The GUI, it says it's using 25% of the memory.
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.

Thanks for the quick respons, but there is no memcached
running on that VM.
Kind regards

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
