I didn't touch the scheduler, just patched the reporting script.
On my system it exists in ~oneadmin/remotes/im/kvm.d/kvm.rb and is
copied by ON (idr when exactly - restart?) to /var/tmp/one/im/kvm.d/ on
every host in cluster.
I just added above lines near the end of script - before printing,
copied it manually and about minute later changes were visible in chart.
Hi,
This file get copied over to the host when oned is restarted. If
you run it on the host it reports the increased memory size. However,
the scheduler seems to ignore this. I'm running version 4.2. Is that
what you are running?
Remember that values reported to ON must be consistent - total == free +
used or ON will ignore them.
That how it's look like on our system:

Hi,
Below is the modified section of kvm.rb. I have only added three
lines to try to report double the actual memory.
39d38
< $total_memory = $total_memory.to_i * 2
70d68
< $total_memory = $total_memory.to_i * 2
75d72
< $free_memory=$total_memory - $used_memory.to_i
When I run the modified kvm.rb on the host it reports back twice the
memory but ON seems to ignore it.
Do you know if VMEMORY has been implemented?
nodeinfo_text.split(/\n/).each{|line|
if line.match('^CPU\(s\)')
$total_cpu = line.split(":")[1].strip.to_i * 100
elsif line.match('^CPU frequency')
$cpu_speed = line.split(":")[1].strip.split(" ")[0]
elsif line.match('^Memory size')
$total_memory = line.split(":")[1].strip.split(" ")[0]
$total_memory = $total_memory.to_i * 2
end
}

line[7..-1].split(",").each{|elemento|
temp = elemento.strip.split(/[% ]/)
if temp[1]=="id"
idle = temp[0]
$free_cpu = idle.to_f * $total_cpu.to_f / 100
$used_cpu = $total_cpu.to_f - $free_cpu
break
end
}
end
}
$total_memory = `free -k|grep "Mem:" | awk '{print $2}'`
$total_memory = $total_memory.to_i * 2
tmp=`free -k|grep "buffers\/cache"|awk '{print $3 " " $4}'`.split
$used_memory=tmp[0]
$free_memory=tmp[1]
$free_memory=$total_memory - $used_memory.to_i
