What is the Available Memory (AMEM) reported by OpenNebula? The way
this value is retrieved depends on the hypervisor. For example, in Xen
this value is reported by xend considering the dom0 memory, therefore
this value will be lower than 16GB

The scheduler also defines a parameter to adjust the fraction of
memory reserved by the hypervisor(HYPERVISOR_MEM) [1], by default is
set to 10%.

I think this error is not related to ACL rules since oneadmin bypass
that module. Myabe it's just a cache problem, try restarting the
occi-server and cleaning the browser cache.

Hope this helps
