[pve-devel] [RFC common/cluster/ha-manager/docs/manager v2 00/40] HA colocation rules

[DERUMIER, Alexandre]

Hi Daniel,

Thanks for your hard work on this.

I don't known if it's the best place, but 1 thing missing currently,
if ressource affinity, like for example,

if a vm use a specific storage, it need to run on a node where the
storage is present.
Same for the number of cores of vm (the host numbers of cores need to
be >= than the vm cores).

I don't known if it could be possible to reuse your rules framework,
and add some kind of implicit rules. (and maybe them dynamic if vm
config change) ? 


With current HA for example, you setup local zfs mirroring between 2
nodes, and if the vm is migrated to the wrong node,  the vm is
completly stuck, and the only way to fix it to disable HA and move the
vm config file manually to the correct node.
