Re: CloudStack affinity group and vSphere DRS

[Yiping Zhang]

Thanks Andrija,

It sure would be nice if CloudStack's anti-host affinity group could be mapped 
to vSphere's corresponding native affinity rules, or any hypervisor's such 
native features if available, for a better integration and experience.

Regards,
Yiping

    Hi Yiping,
    
    unless I'm mistaken, CloudStack should have nothing to do with DRS - it
    only initially chooses the host to which to deploy a VM to, but later
    VMware DRS can kick in and move it on it's own.
    
    Cheers,
    Andrija
