[one-users] Removing old VMs

[Carlos Martín Sánchez]

Hi,

The feature request #1026 [1] can be easily implemented with hooks [2].

For instance, with these two hooks you don't even need any script file:

VM_HOOK = [
   name      = "vmdir_cleanup",
   on        = "DONE",
   command   = "/bin/rm",
   arguments = "-r /var/lib/one/$VMID" ]

VM_HOOK = [
   name      = "log_cleanup",
   on        = "DONE",
   command   = "/bin/rm",
   arguments = "/var/log/one/$VMID.log" ]


If you want to create an external script, please take into account bug
#1036: Local hooks are not executed unless the full path is defined.

That means that this hook won't be triggered:

VM_HOOK = [
   name      = "cleanup",
   on        = "DONE",
   command   = "cleanup.sh",
   arguments = "$VMID" ]


And you must use this one instead:

VM_HOOK = [
   name      = "cleanup",
   on        = "DONE",
   command   = "/full/path/to/cleanup.sh",
   arguments = "$VMID" ]

Cheers.
