<div dir="ltr">Hi,<div><br></div><div>OpenNebula uses the values returned by the hypervisor. So it is reporting the cpu and memory that the VM processes are using, it does not get information from the guest.</div><div><br>
</div><div>If that's what you need, you can use the OneGate component [1] to push information from the guests to OpenNebula. The values printed in the dashboard can be changed in the vms-tab.js file [2] with the name of the attributes reported via OneGate.</div>

<div dir="ltr">After upgrading my OpenNebula from 4.4 to 4.6.2 i've got problem with memory real capacity usage counter. It shows me 100-110% (depending on the vm number). But on the Hosts i can See 14% Real and 16% Allocated usage. Like in screenshots. It's annoying, but can someone help me solving it out?<div>
