Re: [Openstack] How to do when the compute-node is failed.

Beware of those flags though, since everytime you restart the nova-compute service, the running instances on it also reboot.
For an autostart though $virsh autostart $domain would work.
As for the auto-migration, that feature is not implemented actually

Hi:

Two nova.conf flags can be useful for your case:

--start_guests_on_host_boot=true

--resume_guests_state_on_host_boot=true

Best Regards,

Hi all, 
I am confused about how to do when the compute node is failed. For example, if the compute node reboot. I found the VMs on it didn't startup automatically. I must reboot the VMs manually. Is there any way to keep the HA? 
In a bad situation, what should do if the node is crashed? How to keep the VMs migrate to other node automatically?
