# base - contains all resources as entities and defines create, delete, list operations on them
from marvin.lib.base import Account, ServiceOffering, StoragePool, User, VirtualMachine

# common - commonly used methods for all tests are listed here

# Prerequisites:
#  Only one zone
#  Only one pod
#  Only one cluster
#
# Running the tests:
#  If using XenServer, verify the "xen_server_hostname" variable is correct.
#
# Note:
#  If you do have more than one cluster, you might need to change this line: cls.cluster = list_clusters(cls.apiClient)[0]
