OK, my cloud controller is a very poor server: this is the problem.
I temporary moved OpenNebula on one host node and the load is near 0: I
have to spend some money in a new server...

Hello List,
I have installed my servers in datacenter last Friday: I have a Cloud
Controller made on old Xeon quadcore (a dell PowerEdge 860) with 6 GB
RAM and 2x2TB SATA disks and I use it only for storage via MooseFS and
to run OpenNebula daemon; I have also 2 KVM nodes that use VM raw disk
on MooseFS daemon.
I plan to move the datas and some VM from other 2 old PE860 on this
OpenNebula infrastructure and, after that, use the other 2 servers to
add MooseFS nodes to the storage cluster to enable HA.
At the moment I have 10 VM running on this infrastructure, all ready
but with the only load of incoming emails (no DNS, no web sites).
Without OpenNebula runnung, I have a load under 1 process; CPU is 70%
idle and 25% waiting for disk.
This morning, (yesterday was OK) with OpenNebula running I have a load
about 9-10 process; CPU is 0% idle, 0% waiting for disk, 60% system
and 35% nice. RAM is OK: 1 GB used, 1 GB free an 4 GB cached; no swap
at all.
I checked the system for possible rootkits ecc., I checked logs (debug
level 3) and I tried to move out one.db and restart OpenNebula but the
load is always high. Nokogiri gem is installed. Sunstone, radacctd,
econe, ecc. not running, only One daemon.
When I start OpenNebula, if I run "netstat", I see many connection in
"Time Wait" state to MooseFS.
In this situation I don't unterstand if it is a MooseFS problem or a
OpenNebula problem, but without OpenNebula running all KVM VM works
well, no other problems. What can I do to debug (and solve) this?
Thanks,
Alberto
