Machine Creation Services and KMSMarch 30th, 2011 | Posted by in Citrix | Licensing | Microsoft | VDI | Virtualization | Windows 7 | XenDesktop
We’ve written extensively here about the challenges of using Citrix Provisioning Services to provision VMs that require key activation (i.e., Vista, Win7, and Server 2008/2008R2). We publicly rejoiced when the news broke that PVS v5.6, SP1, supported both KMS and MAK activation.
But now, with the advent of XenDesktop 5, there is a new way to provision desktops: Machine Creation Services (“MCS”). As a public service to those who follow this blog, I thought I’d share Citrix’s official statement regarding MCS and KMS activation:
MCS does not support or work with KMS based Microsoft Windows 7 activation by default, however the following workaround has been provided and will be supported by Citrix Support should an issue arise.
For details on the workaround, click through the link above to the KB article.
It does not appear that there is a workaround that will allow MCS to be used with MAK activation, and I saw a comment by a Citrix employee on a forum post that indicated that there were “no plans to support it in the near future.” So…MCS with KMS, yes; MCS with MAK, no.
Not having MAK support probably isn’t a big deal, since the main reason why you would go with MAK activation rather than KMS activation would be if you had fewer than 25 desktops to activate, and if you have fewer than 25 virtual desktops, you may as well just stick with 1-to-1 images instead of messing around with provisioning anyway. But we thought you should know.
