Error instance state after host reboot
I've some trouble with the management of instances. I created an instance attached to a volume, started and it run without trouble. After performing a reboot of the host machine, i cannot start the previous created instance both if the guest instance was running or stopped. When i press the "start instance" button, the instance not start and the only thing to do is to terminate and recreate.

Edit:
Thanks to comments i've found that using virsh command before reboot show a guests machine but after reboot the list command return no guests.
When your host comes back online are you confirming that the nova-compute service is running before attempting to start the instance? Also, when the compute host is back online you usually will have to run
nova reboot <instance>
ornova reboot --hard <instance>
to start the instances.Had to reboot my host machine. After reboot I attempted to start my instance but received the error
Running
nova reboot --hard <instance>
solved my problem TY!
