Cloudstack Migrate VM Query

[Saurabh-iema]

I have setup my cloudstack and deploying the vms inside it now i have a query if one host gets failed then how the vms running on this is going to migrate to other hosts automatically? how can i do that.

I have given HA property to the hosts and also made a service offering of "offer HA" but when I turn off on of my host the vm does not gets migrated to other hosts automatically , how can i get that feature?

i was also facing an issue like if one host goes down , you can not migrate that host-vms to another host not even manually, it will start showing in progress only

@TheKunalSen If you want to be able to put a host into maintenance mode from a DOWN state, you must use the set.host.down.to.maintenance global setting.

[TheKunalSen]

So if I enable that settings then I would be able to migrate the vms from that down host?

@TheKunalSen I apologize, I was multitasking when I first answered and misunderstood the question. No, virtual machines do not migrate if the agent is unavailable; this option simply allows puts the host into maintenance mode (I deleted the wrong answer).

@Saurabh-iema HA is the most controversial, confusing, and I’d even say often useless mechanism in CloudStack. However, once you dive into it, you can find a specific workflow that works for you. Please take a look at this post #12400 (comment) , and I also recommend read documentation.
