Hi, I am working on implementation of this feature based on functional specification [2] and followed by proposal thread [1] below. All changes are being tracked using JIRA ticket [3] using ACS branch 'vmware-disk-controllers' [1] http://markmail.org/thread/en4skoqu4mbitacs [2] Short link for functional specification document - https://cwiki.apache.org/confluence/x/vI5cAg [3] https://issues.apache.org/jira/browse/CLOUDSTACK-4787 Regards, Sateesh > > > > -----Original Message----- > > From: Erik Weber [mailto:terbol...@gmail.com] > > Sent: 15 November 2014 12:01 > > To: dev@cloudstack.apache.org > > Subject: Re: Server 2012 R2 Bug on CS 4.4.0 with vmware hypervisor > > > > There's an issue in jira to allow controller selection, but it has been > > stale for some time. > > > > This is one of the reasons we switched to xenserver. > > > > I believe there's a quick talk on ccceu about the issue. > > > > Erik > > > > Den lørdag 15. november 2014 skrev Michael Phillips > > <mphilli7...@hotmail.com> > > følgende: > > > > > So I was unable to add a data disk to my vm running server 2012 R2 > > > standard, so I started tracking down the issue and I think I found it. > > > So when provisioning a vm running server 2012 R2, CS creates the VM > > > with the "LSI Logic Parallel" adapter.
