I’m trying to play with HA. I’ve enabled it via the interface but the HA state
is labeled as Ineligible.
I’m specifically interested in this:
HA for Hosts
The user can specify a virtual machine as HA-enabled. By default, all virtual
router VMs and Elastic Load Balancing VMs are automatically
Jeremy,
I don't fully understand your question. You say you are interested in
HostHA specifically but then you ask about restarting VMs when a host dies.
This would not be safe as we can't be sure a host really dies unless you
have HostHA enabled. Consequently you can't guarantee the VM won't sudde
I pasted that from the documentation. My end goal is if a VM host dies
completely and I’m not available to fix it, I would like the VM guests that
were running on the failed host to automatically migrate to an available VM
host so the guest instances continue to run. Perhaps that’s not how it
Jemery,
If you don't have IPMI then ACS can not know for sure that the VM won't
come back. If it comes back the VM would be running twice and this must be
prevented at all costs. Maybe I am missing some functionality, and someone
else can give additional options.

I guess I’m looking for a recovery scenario where the dead vm host is not
coming back, failed disk, caught on fire, and a reboot isn’t going to help.
Thanks

Just seems strange. If I have centralized storage and I can migrate live vm’s,
why wouldn’t I be able to take the risk to migrate a dead vm guest, as in, just
start it on another available host and start it and consider it migrated. If
the original vm host happens to come back up and the insta
because it might still run or be restarted on the unreachable host.

Hi Jeremy,
I remember seeing this is the documentation, the section about Host HA, is just
a duplication of VM HA. I think this was copied and pasted in error by the
author.
For Host HA to work, you would need at least 3 hosts, all with Out of band
management enabled.
