description |
We have most reliably reproduced this on a Standard_B1s in Azure in the North Europe region (>80% of the time). Tests in other regions/VM types do not show this failure as often (<1%). We have reproduced this in Xenial, Bionic, Focal, and Groovy. We saw an increase of test failures around a month ago.

[Test Case]
There two main scenarios that need to be tested:
1. Azure instances:
- Just start an azure instance using our Ubuntu images and check the the status of the hv-vss-daemon and hv-fcopy-daemon services using systemctl.
- If the issue is solved they shouldn't be listed as failed.
2. Local Hyper-V VM:
- Create a local Hyper-V instance and enable the two systemd services if necessary (hv-vss-daemon and hv-fcopy-daemon) and reboot.
- You can change the integration services that are enable to the guest.
1. With desktop integration and the backup feature disabled, the hv-fcopy-daemon and the hv-vss-daemon service, respectively should not be listed as failed.
2. With the same features enabled the services should start without errors.
[Regression Potential]
The major risk with a potential regression is that those systemd service units are shipped by a package produced by our generic kernels and not the linux-azure kernel. So in case of a regression we might need to re-spin the generic kernels. |
