Bug

Description

Three unit tests are failing:

1. Config with YAML config file - should return error for missing file (config_test.go:152)
2. WaitForVMReady - should return error on timeout (wait_test.go:100)
3. WaitForVMReady - should retry when VMI not found and eventually timeout (wait_test.go:108)

Sub-issues

• Fix config test assertion for missing file scenario
• Fix wait package timeout error message
