iiuc, the most obvious change to mention is addition of an 'arch' field 
to cluster, which would affect the list of supported cpu families, etc.?
(and to later know to filter all other aspects of entities based on this 
arch field)?

list of possible arch's would be per cluster compatibility level.
i'd expect default for API of this field to be x86_64 for backward 
compatibility, so it is not mandatory.
I'd also prefer this field to be disabled or hidden if there is only one 
option available in it.

it gets more complicated, as VMs can be moved around between clusters, 
exported/imported, etc.

you would need to validate a VM isn't moved to a cluster with a 
different arch, or imported into a cluster with a different arch as well.
(probably more like that).

i assume the config to filter device types per arch like the network 
devices is also for console (spice), audio, etc.

the system already has the concept of filtering per cluster level, so 
filtering per cluster level and arch would mean reviewing all places in 
code for that.
