Doing some intensive simulation on Autodesk Maya Bifrost, requiring about 50 min per frame on a F48_v2 VM, so that is forecasted to require 40 hours to complete.
I tried twice to complete the sim, and in both cases I discovered the VM was rebooted without my command. On my office PC I can run 8+ hours sim without problems.
The diagnostics say "A reboot was triggered from inside the virtual machine". Running the Troubleshooting tool told me "We identified that a live migration was performed on the VM [VMName] by Azure".
Wanted to ask if this generic message need to be considered valid for my specific instance, and in this case if I need to migrate to a G, M, N, and H series to avoid live migration.

Opened a case and chatted with the support, in the end tracked down the reboot due to Windows update.
Paused the update till the weekend and launched another sim, let's see if will run to the end.

Thanks for sharing the details.
Once you confirm that the issue is resolved and it was caused by Windows update, requesting you to write the cause as answer and accept it as answer for benefit of community.
The sim is running fine since 25 hours so I think definitelly suspending the Windows update was the solution.
Hope it make trough it's forecasted 60 hours (changing a few parameters increased to 1h33 the time per frame) before completion without any more problems.
