However, we also assume that= this scenario would not arise i.e. theoretically, in a cloud, a service pr= ovider always has capacity i.e. request for a VM should not fail, unless th= ere are any specific conditions attached (such as request with a tag and th= ere is no host that has that tag available etc.) Hari -----Original Message----- From: Deepti Dohare [mailto:deepti.dohare@citrix.com] Sent: Wednesday, January 23, 2013 9:44 PM To: Kiran Koneti Cc: cloudstack-dev@incubator.apache.org Subject: RE: [DISCUSS] Dedicated Resources: Dedicate Pods, Clusters, Hosts = to a domain 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 Fun= ctional Spec . Hi Deepti , I have gone through the FS located in the below location and have some ques= tions regarding the feature. FS Link: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Dedicated+R= esources+-+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 featu= re.) [deepti] Are you asking about this feature: https://cwiki.apache.org/conflu= ence/display/CLOUDSTACK/VMs+on+hardware+dedicated+to+a+specific+account ? T= his feature is combined with the feature: Private pod, cluster, host (see t= he 2nd row in the table). 2) How are we going to dedicate the pod/cluster/host to a particular a= ccount(are we using only api's or there any UI changes also to implement th= e 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 host= s 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 o= r 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 Servic= e 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 t= he 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 th= eUUID's). [deepti] Like all other APIs, this use case will also be taken care of.
