I think I see what went wrong by looking at the documentation.
The value as shown in onehost show -x
is now labeled FREE_MEM instead of FREEMEMORY.
(The current docs also correctly show the variable as FREE_MEM).
I will edit my template and see if that has an effect.
Also it looks like RANK is deprecated in favor of SCHED_RANK
and SCHED_DS_RANK is that correct?
Any way short of a text editor and onetemplate update to
fix all the legacy templates that have it wrong?

Hi Steven,
This should be working as long it is in the host information. Could you send
the onehost show -x for one of the hosts? (You can send it to me offlist if
there is any sensible information).
The Rank expression is supposed to work with any variable under the
following XPaths:
"/HOST/TEMPLATE/",
"/HOST/HOST_SHARE/",
"/HOST/",
"/HOST/CLUSTER_TEMPLATE/
Cheers

Under OpenNebula 3 we have been using RANK=FREEMEMORY
to launch the next virtual machine on the hypervisor which
has the most memory available at the time. I am using the
same in OpenNebula 4.8 but it does not appear to be working,
even though FREEMEMORY is still a documented selection variable
in the requirements section. In particular
all the RANKS of the machines show up as "0" in the sched.log
when you look at the allocation cycle and there is no
"FREEMEMORY"
variable reported in the output of
onehost show xxxx
under opennebula 4.8.
Are there other selection variables which could have
the same desired effect, i.e. a horizontal fill of the cloud?
