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

It wasn't, the last time we tried a test upgrade using the<br>
upgrade scripts. There were a lot of deprecated fields that stayed<br>
in the machine templates and some required ones that didn't get in.<br>

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

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