Hi I've setup Hyper-V compute services and attached it to a controller infrastructure. I can boot images sucessfully and I can start, stop and resize vms. I now shutdown an instance from the console in Hyper-V. However the instance is still marked as active in nova. Am I missing some configuration to make nova get state changes triggered from the hypervisor ?

Update, I found that the state gets updated in a way that if the instance is marked as shutoff in nova and running in Hyper-V. Nova will initiate a shutdown and the instance is powered off in Hyper-V. Can this behaviour be changed so that it is the other way round Nova will mark instance as running

Instances created by Nova are supposed to be managed (and thus shut down) by Nova. Said that Nova checks e.g. when nova-compute starts if the VM is active and updates the instance status accordingly.

This applies to every Nova diver (libvirt/KVM, ESXI, Hyper-V, etc), so requests to change this behaviour should be brought to the attention of the general OpenStack community (e.g. OpenStack Dev ML, etc)

Thanks for your answer. This makes sense to me. I found out that there is a setting in nova called sync_power_state_interval. If you set this to -1 then nova seems to not sync the power states but leaves the powerstate independent of each other.
