So we are betting on this solution. We are hopeful.
Quoting this again, so you don't need High Availability, you just need near HA, 99.9% uptime. Use Continuous Replication, I assume you've installed Xen Orchestra to administer these hypervisors, correct?
If not, see my github
I was thinking the same thing. The only thing is that there is no fail-over mechanism in Xen Orchestra for this right?
So if one host fails, you have to start the replicated VMs on the other host manually. Is that correct?
You're asking "how do we ensure the system is running" and the challenge to that is even with HA, the Host doesn't know that the guest is actually hosting services, it just knows that it's powered up (or attempting to start).
The services this guest is providing (and if its running or not) is something of a fuzzy situation.
You can get the guest to automatically start on the remote if a host goes offline by enabling HA (auto start) with best effort for the pool.
But this is again a "fuzzy" situation because running to the Host means "I see it has "power" so it must be running."
Running to your users means "I can access the services this system is hosting." Your mileage may vary...
