How to install synergy on the controller:

cd /root/FOR_SCHEDULER

scp blade-03-06.pn.pd.infn.it:/tmp/synergy.tar .

cp synergy.tar /usr/lib/python2.7/dist-packages/.

cd /usr/lib/python2.7/dist-packages/

tar xvf synergy.tar

cd synergy

apt-get install python-mysql.connector

apt-get install python-dateutil

useradd -r synergy

cp script/synergy.conf /etc/init/synergy.conf

chmod a+r /etc/init/synergy.conf

cp scripts/synergy-server /usr/bin/synergy-server

chmod 755 /usr/bin/synergy-server

mkdir -p /etc/synergy/

chown -R synergy:synergy /etc/synergy/

mkdir -p /var/log/synergy/

chown -R synergy:synergy /var/log/synergy/

mkdir -p /var/run/synergy/

chown -R synergy:synergy /var/run/synergy/

chmod 755 -R /etc/nova/

cp config/synergy.conf /etc/synergy/synergy.conf

chown -R synergy:synergy /etc/synergy/synergy.conf (to be customized)

in /etc/nova/nova.conf add to the [DEFAULT] section, if missing, the following parameters:

notify_on_state_change = vm_state

notification_driver = nova.openstack.common.notifier.rpc_notifier

notification_topics = notifications

cpu_allocation_ratio = x (to set)

ram_allocation_ratio = y (to set)

Create dynamic tenants:

keystone tenant-create –name batch-short –description "FairShare short queue Tenant"

keystone tenant-create –name batch-long –description "FairShare long queue Tenant"

Create related networks:

neutron net-create int-batch-short –router:external=False –provider:network_type gre –provider:segmentation_id 108 –tenant_id $(keystone tenant-list | grep batch-short | awk '{print $2}')

neutron net-create int-batch-long –router:external=False –provider:network_type gre –provider:segmentation_id 109 –tenant_id $(keystone tenant-list | grep batch-long | awk '{print $2}')

It is possible to use a synergy shell to get info about quota and priority

cd /usr/lib/python2.7/dist-packages/synergy/common/client

python shell.py get_priority

python shell.py get_quota
