Subject: KVM Host HA Settings
Hi,
Bringing in new KVM hosts to CS 4.18.0.0.
How do you all configure Cloudstack to use "Host HA" for KVM hypervisor (preferably CS 4.18.0.0)?
Thanks so much!
Mit freundlichen Grüßen / With kind regards

If you only have local storage, then Host HA may make sense, at least if
the hypervisor crashes have it rebooted via ipmi.
Test it and see if it behaves as expected.

Re: AW: KVM Host HA Settings
Posted by Nux <nu...@li.nux.ro>.
Hello,
"By definition" you cannot have VM HA with local storage.
If your hypervisor goes down, through what process will the storage of
your VM be moved to another hypervisor and started there?
For VM HA you always must have network/shared storage, be it CEPH,
Storpool, Linbit etc - and always you need some NFS share for the
heartbeat - if the heartbeat NFS share were to become unavailable all
the hypervisors will fence themselves (forced reboot).

Re: AW: KVM Host HA Settings
Posted by Granwille Strauss <gr...@namhost.com.INVALID>.
Hi Nux
So we cannot run VM Ha on strict KVM local storage? Or can we keep this
configuration of local storage and set up a temp NFS Primary storage
just for the hearbeat process to work?

Re: AW: KVM Host HA Settings

I would avoid using host HA, I am not sure it can be relied upon
currently and one thing I know for sure is that it breaks VM HA.
I would just rely on the VM HA feature and disable host HA altogether.
Do note, VM HA requires an NFS storage for the hearbeat etc and it needs
to be stable otherwise hosts will begin to fence themselves.
