machine/hyperV: move ssh mounts to after the ready check#28871
Merged
Conversation
We are seeing frequent flakes in hyperV machine tests. The machine start fails with an ssh handshake failure: ssh: handshake failed: read tcp 127.0.0.1:56425->127.0.0.1:56377: wsarecv: An existing connection was forcibly closed by the remote host. Normally we do the ssh probe in conductVMReadinessCheck() with a retry mechanism, however because the hyperV mount code already used ssh in PostStartNetworking() we never got there and failed early. PostStartNetworking seems the wrong place to mount anyway so move this to MountVolumesToVM() instead which is placed after the ready check already so it should have a working ssh by then.

Mhh, that does not seem to work and still fails, though now with the longer retry timeout so it seem like ssh not coming up at all or a gvproxy error seems more likely. |

Even if it's not fixing the issue, still LGTM for me - this is a much cleaner way of doing things and should be less race-prone |

I Agree it is worth merging reagrdless but unlikely to fix the root cause of the flake. Maybe it helps a bit, hard to tell from just one PR run. @baude PTAL |
