[ovirt-users] Re: Question on "Memory" column/field in Virtual Machines list/table in ovirt GUI
For some OS versions , the oVirt's behavior is accurate , but for other versions
it's not accurate.
I think that it is more accurate to say that oVirt improperly calculates memory for SLES
15/openSUSE 15.
I would open a bug at bugzilla.redhat.com .

Hi,
I think I already checked that.
What I meant (since beginning) was that ovirt is reporting memory usage in GUI same way
regardless of CentOS or SLES in our case.
My main question is why ovirt is reporting memory usage percentage based on
"free" memory but not actually based on "available memory", which is
basically sum of "free" and "buff/cache".
Buffer/Cache is a temporary memory and that's anyhow gets released for new processes
and applications.
That means that, ovirt should actually consider the actual available memory left and
report usage accordingly in GUI but what we see now is different behavior.
I was very worried when I saw the memory usage as 98% and highlighted in red for many of
VMs in GUI. But, when I checked the actual used memory by VM, it's always below 50%.
Could you clarify how can this behavior from ovirt be OS specific?
I hope I explained the issue clearly or let me know if it is still unclear.
Thanks in advance.
