# Prerequisites:
# Only one zone
# Only one pod
# Only one cluster (two hosts for XenServer / one host for KVM with another added/removed during the tests)
#
# Running the tests:
# Change the "hypervisor_type" variable to control which hypervisor type to test.
# If using XenServer, set a breakpoint on each test after the first one. When the breakpoint is hit, reset the
# added/removed host to a snapshot state and re-start it. Once it's up and running, run the test code.
# Check that ip_address_of_new_xenserver_host / ip_address_of_new_kvm_host is correct.
# If using XenServer, verify the "xen_server_master_hostname" variable is correct.
# If using KVM, verify the "kvm_1_ip_address" 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] and
# this variable's value: TestData.clusterId.
