Reset the virtual machines at the end of a semester
After a semester, when WEA or SAD class is over, you must reset the
machines web1... web15
or sad1-a... sad5-b.
The following script erase the permissions and reset the hard
disks, so you don't have to VMware GUI and reset machine by machine by
hand.
- Login on the VMware server:
$ ssh root@virtual3
- Call the script for one or more WEA virtual machine. For the machine web1 use the pamater 1, use 2 for web2, etc.:
$ /vmfs/volumes/datastore1/ghettoVCB/reset-vm.sh machinea machineb...
The shell script does the following:
- stop the virtual machine
- find and remove any permission associated to the VM
- delete the virtual disk, care is taken to fine the proper xxx-flat.vmdk file
- delete any log
- delete any NVRAM (*.nvram, in case of WEA machines, the file is always web1.nvram) because all machines were cloned from web1)
- delete any lock file
- delete any swap file
- remove any files used by snapshots
- remove the file linked to VMware tools
- recreate an empty virtual disk with the same name used at deletion step above, make the disk accessible only by root
- Automatically add permission for Matt on all the WEA virtual machines
