HA coverage and options

[hac3ru]

Hello,

I searched the web for this but was unable to find anything related. What I am interested in is a way to view which VMs are not covered by HA. Is there such a list present anywhere / can we somehow put that together?

Also, in our setup, we got multiple hosts running Proxmox and we have 2-3 VMs that are serving the same purpose. Obviously, I would love those VMs to run on different physical hosts, without having to specify the hosts. Is there a way to do this? For example: let's say we have three DB VMs (DB nodes in a cluster) which we want to run on ANY PVE host, but we don't want them to be on the same host. So I'm thinking of creating a group with those two VMs and having a checkbox or something saying "Do not run these VMs on the same host".

If this is already implemented, please point me in the right direction, otherwise I'm happy to open a feature request.

Thank you!

You will have to open a feature request for that.

Copy that.

What about the first question? A list of non-covered HA VMs?

P.S. leaving this here for further refferrence - is someone comes across this post: https://bugzilla.proxmox.com/show_bug.cgi?id=5260

A list of non-covered HA VMs?

You would have to create a delta from the list of HA-VMs and all VMs.

ha-manager status gives you the list of HA-VMs.

You are asking for anti-affinity and it's not there, the stack is rather simple, see answer:
