Subject Re: Implicit dedication vs Explicit dedication
Date Thu, 06 Oct 2016 06:38:19 GMT
Hi Rafael,

I hadn't tried allocating more VM's until the host gets full. If this
feature was available and it was possible to both dedicate a pod to an
account, and force an account to only use that pod, I would want requests
to fail once this pod is full.

When I said the following with regards to the ImplicitDedicationPlanner:

"When the account selects this service offering, the instance is created on
an empty host. Addition instances created with this service offering then
get put onto the same host, rather than looking for other free hosts within
the same pod."

It seems that what happens is when you set this up you must have a free
host available within cloudstack, it doesn't matter which POD this host is
in. When you create a VM which has this service offering, cloudstack will
select a host a host to use. From this point on other VM's which have this
service offering are placed on the same host. But I as I said, I didn't try
to keep allocating vm's until that host was full as well. However it didn't
appear to me that it would force an account to stick to one pod only.

This is from memory, I'm not in a position to retest this at the moment.

I guess what I am asking is if it is possible with the latest version of
cloudstack to both dedicate a pod to an account, and force an account to
only be able to use that pod.

Cheers!
