[ovirt-users] Re: Question re: MaxFreeMemoryforOverUtlized and MinFreeMemoryforUnderUtilized
Hi, it is just a matter of perspective:
MaxFreeMemoryforOverUtlized - the host is considered over utilized
when the free memory is below defined maximum value
MinFreeMemoryforUnderUtilized - the host is considered under utilized
when the free memory is at least the defined minimal value
Best regards
