Hi Kiran, See my comments inline. Thanks Deepti
-----Original Message----- From: Kiran Koneti Sent: Wednesday, January 23, 2013 3:16 PM To: Deepti Dohare Cc: cloudstack-dev@incubator.apache.org Subject: Regarding the Dedicated Resources - Private pod, cluster, host Functional Spec . Hi Deepti , I have gone through the FS located in the below location and have some questions regarding the feature. FS Link: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Dedicated+Resources+-+Private+pod%2C+cluster%2C+host+Functional+Spec Here are the List of Questions: 1) Is the "Dedicated Resources Specific to OS on Dedicated HW" Feature also added to the same FS.(as I see that both got merged to a single feature.) [deepti] Are you asking about this feature: https://cwiki.apache.org/confluence/display/CLOUDSTACK/VMs+on+hardware+dedicated+to+a+specific+account ? This feature is combined with the feature: Private pod, cluster, host (see the 2nd row in the table). 2) How are we going to dedicate the pod/cluster/host to a particular account(are we using only api's or there any UI changes also to implement the same.) [deepti] We are going to dedicate the resources using APIs only which will be added as a part of the plugin. 3) If I dedicate a pod to an account then it is equal that I dedicated the cluster as well as the hosts in that cluster to the account? [deepti] If we dedicate a pod to an account, then all the clusters and hosts inside the pod will be automatically dedicated to that account. 4) Adding to the above if I have a cluster with two hosts then can I dedicate each host to a different account? [deepti] Yes we can dedicate two clusters to two accounts unless clusters or pods to which the host belongs, is not dedicated to any account/domain. 5) I have a host dedicated to an account but if I won't use the Service offering with "isdedicated" to true and use any other offering will the VM be deployed? (case is there are no other non dedicated hosts in the pool.) [deepti] According to me, the vm deploy operation will fail if there are no non-dedicated hosts available. Will confirm this scenario. 6) Will we use the UUID or just the ID of the pod/cluster/host in the api to dedicate a particular host. [Deepti] We are using only the UUIDs of the pod/cluster/host to dedicate the resource. 7) Can we implement the same in the Upgraded environment also (If the "UUID" concept is used as the hosts upgraded from 2.2.14 doesn't contain theUUID's). [deepti] Like all other APIs, this use case will also be taken care of.
