Looks really cool. Good job! What do you think of making the backing up
into a loop and fetching VMs from a list? My thinking is that you
usually have more than one VM you´d want to back up, so something like
this maybe:

def getVMsFromList(VMS_LIST):
    try:
        print 'Getting list of VMs from file \"%s\".' % (VMS_LIST)
        fo = open(VMS_LIST)
        output = []
        for line in fo:
            strippedline = line.strip('\r\n')
            output.append(strippedline)
        fo.close()
        return output
    except Exception as e:
        print 'Exception in getting list of VMs:\n%s' % str(e)
        exit(1)

And then you can loop:
for LIST_VM_NAME in getVMsFromList('VMs.list'):
    ....

Or to have the list of VMs in the config and then:
config = Config(config_file, debug)
VMS_LIST = vms_list
for LIST_VM_NAME in getVMsFromList(VMS_LIST):
    ....
