Subject: [Discuss] FS review-VMWare(Supporting DRS, HA

Hi Hari,

am the QA resource for this feature. I have reviewed the Functional spec and please find the review comments below:



1.    Are we going to implement Cloudstack HA support for VMware or still will depend on Native HA.

2.    Is the  Cloudstack HA support for VMware is only for DRS enabled cluster.

3.    Are we going to address  open vmware vmsync issue as part of this feature enhancement.

4.    please provide/update the FS with Flow/ implementation details ,like


n  How are we going to handle the power management

n  What happen CS and DRS tries to control the same vm at same time

n  How the CS will query/get info from DRS

n  Earlier  when the DRS enabled ,CS has no idea where the VM moved but it will try to query  all the hosts till it finds the moved VM by DRS and it will update the  host as  parent host. Now how this behaviour will work with your implementation.



n  How the Cloudstack handle VM replacement when& after Vm has been started

5.    DRS with fully automated will impact host/cluster performance and network. Not sure why we added as requirement in FS (CloudStack must be able to support HA, load balancing and power management in a DRS cluster that is setup in a fully automated fashion )is there any specific reason.
