[Kernel-packages] [Bug 1701222] Re: [Hyper-V] LIS daemons fail to start after disable/re-enable VM integration services
The unit entered a failed state, and thus would not automatically started until failed state clears. Why does bouncing of the services result in the daemon exiting with an error condition? Should that particular exit code result in a graceful shutdown of the service, such that the unit can be restarted again? What userspace events should be causing the start of this unit? a udev event / udev rule? a .path unit monitoring sysfs or some such? Is it possible to reproduce this on e.g. azure for me to investigate? I'm going to remove per-series tasks from systemd, until this issue is trianged. per-series tasks on the src:systemd package are used to track fixes/patches which have been developed and are ready for inclusion in the distribution. ** No longer affects: systemd (Ubuntu Artful) ** No longer affects: systemd (Ubuntu Zesty) ** No longer affects: systemd (Ubuntu Xenial) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701222 Title: [Hyper-V] LIS daemons fail to start after disable/re-enable VM integration services Status in linux package in Ubuntu: In Progress Status in systemd package in Ubuntu: New Status in linux source package in Xenial: In Progress Status in linux source package in Zesty: In Progress Status in linux source package in Artful: In Progress Bug description: Issue description: Hyper-V daemons fail to start after disable/re- enable VM integration services.

Ok, I reread the bug description and more importantly, comment #15. So it sounds like the first issue has been fixed in all kernels since kernel version 4.4.0-2, but that is when the second issue was introduced. If that is the case, we should focus on the second issue, where the daemons do not automatically start after the integration service is disabled and then enabled again.

Thanks for the clarification. Since there are two issues, we should probably focus on one at a time.

[Kernel-packages] [Bug 1701222] Re: [Hyper-V] LIS daemons fail to start after disable/re-enable VM integration services
I have tested the kernel provided with commit ef754413085f5 and the bug persists. The daemons do not stop if the integration services are being disabled. The kernel provided in comment #36 was not affected by the bug. That was the first good commit. Regarding comment #27, the kernel tested was reported as bad (the daemon still remains running after the integration service is being disabled). Just to make sure we got this right, there are 2 issues right now: 1. The daemons do not stop if the integration service is being disabled, they remain running in the process list, but are not functional. This issue is present in the kernels tested up to 4.4.0-2. This issue is NOT present in kernel 4.4.0-3, here the daemons processes do stop if the integration service is disabled. Regarding this issue, the kernel provided in comment #36 is a good kernel. 2. The daemons do not automatically start after the integration service is disabled and then enabled again. This is the initial bug discovered in 16.04 and 17.04.
