OpenNebula

The sample script (http://docs.opennebula.org/4.12/advanced_administration/application_insight/onegate_usage.html#sample-script) can produce invalid variable names with hyphens in them when run on a VM using LVM, where 'df' output gives names of the form /dev/mapper/$VGNAME-LVNAME. The error response probably makes sense to whatever parser is choking on the variable name, but it is not obvious what is wrong to a user, e.g.:

  [VirtualMachineUpdateTemplate] Cannot update template. Parse error: syntax error, unexpected VARIABLE, expecting EQUAL or EQUAL_EMPTY at line 1, columns 5:8[root@crm-pm ~]
