I will edit my template and see if that has an effect.<br>

Hi Steven,<br>
This should be working as long it is in the host information. Could you send<br>
the onehost show -x for one of the hosts? (You can send it to me offlist if<br>
there is any sensible information).<br>
<br>
The Rank expression is supposed to work with any 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 RANK=FREEMEMORY<br>
to launch the next virtual machine on the hypervisor which<br>
has the most memory available at the time. I am using the<br>
same in OpenNebula 4.8 but it does not appear to be working,<br>
even though FREEMEMORY is still a documented selection variable<br>
in the requirements section. In particular<br>
all the RANKS of the machines show up as "0" in the sched.log<br>
when you look at the allocation cycle and 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 could have<br>
the same desired effect, i.e. a horizontal fill of the cloud?<br>
