A set of shell scripts to deploy an arbitrary number of instances on a node for various load testing purposes.
These scripts need the usual suspects in Linux virtualization installed. Installing libvirt and qemu-kvm should get you there.
To configure edit conf/settings to suit your needs. Copy your template to the VOLUMEPATH indicated in the settings file to the indicated TEMPLATE_NAME. Make sure the template includes the node's ~root/.ssh/id_rsa.pub key in the TEMPLATE_USER's ~/.ssh/authorized_keys. Finally:
# source vars
To deploy 25 instances, first setup the node networking and then create the VMs.
# node_setup_networking
# node_create_vms 25
To cleanup, simply delete the instances and teardown the networking setup.
# node_delete_vms
# node_teardown_networking
After creating the VMs, you can check how many are up and running with an IP allocated:
# node_check_vms_running
Numer of VMs up and running: 5
test-vm-27299-1
test-vm-27299-2
test-vm-27299-3
test-vm-27299-4
test-vm-27299-5
Once the instances are up you can execute commands in parallel on each instance:
# vms_execute_cmd "echo Hello..."
Hello...
Hello...
Hello...
...
