Re: [pve-devel] [RFC cluster/ha-manager 00/16] HA colocation rules

["DERUMIER, Alexandre" <alexandre.derumier@groupe-cyllene.com>]

Hi Daniel,

thanks for working on this !

>>each other in contrast to locating services on nodes, but no hard
>>feelings to change it (same for any other names in this series).

my 2cents, but everybody in the industry is calling this
affinity/antiafifnity (vmware, nutanix, hyperv, openstack, ...).
More precisely, vm affinity rules (vm<->vm)   vs  node affinity rules
(vm->node , the current HA group)

Personnally I don't care, it's just a name ^_^ .  

But I have a lot  of customers asking about "does proxmox support
affinity/anti-affinity". and if they are doing their own research, they
will think that it doesnt exist.
(or at minimum, write  somewhere in the doc something like "aka vm
affinity" or in commercial presentation ^_^)




More serious question : Don't have read yet all the code, but how does
it play with the current topsis placement algorithm ?




>>Additional and/or future ideas
>>------------------------------

Small feature request from students && customers:  they are a lot
asking to be able to use vm tags in the colocation/affinity





>>I'd like to suggest to also transform the existing HA groups to

I agree with that too



Thanks again !

Alexandre
