Script make creation and managing VirtualBox machines cluster easier.
- Linux base system
- VirtualBox
➜ vbox_cluster git:(master) ✗ ./vcm.sh help
Usage:
./vcm.sh [parameters]
start behavior Start VM stack defined in file, possible behaviors: headless, separate, gui
start behavior destinationVmName Start specific VM
start h Start vm stack in headless state
stop behavior Stop cluster with specific behavior: acpi, savestate, poweroff, pause
If machine not turning within 40 sec script ask about killing VirtualMachine
stop behavior destinationVmName Stop specific virtualmachine
stop a Stop vm stack with acpi power button
clone "sourceVmName" "destinationVmName" Clone specific vm one time, you can only clone already registered vm
clone "sourceVmName" "destinationVmName" number_of_copies Create multiple clones of virtual machine
clone "vm1" "vm_cluster" 3 It creates 5 clones with name vm_cluster-1, vm_cluster-2, vm_cluster-3
After clone script ask for updating vm list in text file
restart Restart all cluster, Stopping behavior: acpi power, Starting behavior: headless
restart destinationVmName Restart specific vm
command "some command" Run command vms times on host, Patterns to substitute: vmname: #vm , index: #i
command "VBoxManage startvm "#vm" --type headless"
command "vboxmanage controlvm #vm natpf1 'OpenSSH,tcp,,200#i,,22'"
delete Delete all VMs defined in the mange file
delete destinationVmName Delete specific virtual machine
dumplist all Save list of all VMs currently registered on virtualbox into manage file.
dumplist run Save list of running VMs currently into manage file.

[INFO] End process of VMs removal.- Add all possibilities gathering ip address (DHCP, Guest addon, static)
- Add cluster configuration (Network, Storage, etc.)
- Improve execution over ssh (
./vcm.sh exec) - Port to python
- Add support to another virtualization applications
