78-80: LGTM! Consider enhancing the error message.The error handling is correctly placed before any list indexing operations, preventing the IndexError. However, the error message could be more specific about the cause.
Consider this enhanced error message:
- raise ResourceNotFoundError(f"VIRT launcher POD not found for {self.kind}:{self.name}") + raise ResourceNotFoundError( + f"No virt-launcher pod found for {self.kind} '{self.name}'. " + f"The pod might not have been created yet or was terminated." + )
Line range hint
133-147: Consider enhancing error logging in wait_until_running.The error handling flow is good, but the debug information could be more comprehensive.
Consider adding VMI status logging:
try: self.wait_for_status(status=self.Status.RUNNING, timeout=timeout, stop_status=stop_status) except TimeoutExpiredError as sampler_ex: if not logs: raise try: + self.logger.error(f"VMI status: {self.instance.status}") virt_pod = self.virt_launcher_pod self.logger.error(f"Status of virt-launcher pod {virt_pod.name}: {virt_pod.status}") self.logger.debug(f"{virt_pod.name} *****LOGS*****") self.logger.debug(virt_pod.log(container="compute")) except ResourceNotFoundError as virt_pod_ex: - self.logger.error(virt_pod_ex) + self.logger.error( + f"Failed to get virt-launcher pod logs: {virt_pod_ex}. " + f"This might indicate that the pod creation failed or was delayed." + ) raise sampler_ex

Line range hint 3-3: Verify usage of virt_launcher_pod property.
Let's verify other methods that might need similar error handling when accessing the virt_launcher_pod property.
✅ Verification successful
Let me analyze the usage of virt_launcher_pod to verify if similar error handling is needed in other methods.
The error handling for virt_launcher_pod property is already properly implemented
The property virt_launcher_pod already has appropriate error handling:
- Raises
ResourceNotFoundErrorwhen no pods are found - Handles migration scenarios by correctly selecting the target pod
- All methods using this property (
execute_virsh_command,get_uid, etc.) will automatically inherit this error handling
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Find all usages of virt_launcher_pod property to verify error handling
# Search for methods accessing virt_launcher_pod
ast-grep --pattern 'self.virt_launcher_pod'
# Search for direct property access
rg '\bvirt_launcher_pod\b' -A 2 -B 2
Length of output: 3130
Script:
#!/bin/bash
# Let's examine the implementation of virt_launcher_pod property and its error handling
ast-grep --pattern $'@property\n def virt_launcher_pod(self):\n $$$'
# Also check the error handling in the methods that use it
ast-grep --pattern $'def execute_virsh_command(self, $_):\n $$$'
