Open Stack

Hi yongiman:

Your idea is good, but I think the auto HA operation is not OpenStack’s business. IMO, Ceilometer offers ‘monitoring’, Nova  offers ‘evacuation’, and you can combine them to realize HA operation.

So, I’m afraid I can’t understand the specific implementation details very well.

Any different opinions?

Hi,

Now, I am developing auto ha operation for vm high availability.

This function is all progress automatically.

It needs other service like ceilometer.

ceilometer monitors compute nodes.

When ceilometer detects broken compute node, it send a api call to Nova,
nova exposes for auto ha API.

When received auto ha call, nova progress auto ha operation.

All auto ha enabled VM where are running on broken host are all migrated to auto ha Host which is extra compute node for using only Auto-HA function.

Below is my blueprint and wiki page.

Wiki page is not yet completed. Now I am adding lots of information for this function.

Thanks
