hi all i have set
reserved_host_memory_mb in nova.conf of controller and compute and
restarted necessary services.
i am expecting scheduler to not pickup host that has less than what is
reserved_host_memory_mb
in my example i put reserved_host_memory_mb = 1024
and free RAM in compute node is 700 Mb.
But still scheduler chooses this host and created a new instance on it.I am
expecting scheduler to show "No valid Hosts found" as it has less ram
than reserved_host_memory_mb
= 1024

Can some one help me understand this value

Thanks
