Pull request overview
This PR fixes the km_ebpfcore_restart_test CI job by routing execution through the existing VM-based test execution path, ensuring the restart controller runs inside the Hyper-V VM where ebpfcore is installed.
Changes:
- Update the
km_ebpfcore_restart_testworkflow command to callexecute_ebpf_cicd_tests.ps1with a new stress-test option (RestartEbpfCore). - Add a
RestartEbpfCoreswitch toInvoke-CICDStressTeststo runebpf_restart_test_controller.exevia the standard VM test harness. - Plumb the new option through
vm_run_tests.psm1option parsing and intoInvoke-CICDStressTests.

Runs the restart test through execute_ebpf_cicd_tests.ps1 so it executes inside the VM. |

Recognizes RestartEbpfCore in -Options and forwards it to stress test invocation. |
scripts/run_driver_tests.psm1 |
Implements RestartEbpfCore handling in Invoke-CICDStressTests to execute the restart controller. |

The restart test controller was invoked directly on the 1ES runner host, but ebpfcore is installed inside the Hyper-V VM. This caused error 1060 (ERROR_SERVICE_DOES_NOT_EXIST) since the service doesn't exist on the host. Route the test through execute_ebpf_cicd_tests.ps1 with a new RestartEbpfCore stress test option, matching the pattern used by km_mt_stress_tests_restart_extension. Fixes microsoft#4950

Problem
The
km_ebpfcore_restart_testhas been failing every scheduled run since it was introduced (issue #4950). The previous RCA (Chocolatey missing) was fixed by PR #4968, but the test continues to fail with a new error:Failed to create map, error: -1 Failed to open ebpfcore service, error: 1060 FAIL: ebpfcore service does not exist - environment issue!Root Cause
The test command
.\ebpf_restart_test_controller.exewas invoked directly on the 1ES runner host, but the eBPF components (ebpfcoreservice) are installed inside the Hyper-V VM (runner_vm) bysetup_ebpf_cicd_tests.ps1. Error 1060 isERROR_SERVICE_DOES_NOT_EXIST.Other KM tests (e.g.,
km_mt_stress_tests_restart_extension) correctly route execution throughexecute_ebpf_cicd_tests.ps1, which usesInvoke-OnHostOrVMto run inside the VM.Fix
Route the restart test through the existing VM execution infrastructure:
