Hi Mardan, Assuming that you meant openstack rather than cloudstack(!) then check out the guide at http://blogs.citrix.com/2012/09/06/vhd-to-openstack-using-a-xapi-host-plugin/. VHDs in OpenStack are actually a TGZ - since it can contain a VHD chain - with each VHD renamed to "0.vhd", "1.vhd" according to it's position in the chain. Also see http://blogs.citrix.com/2012/10/17/upload-custom-images-to-a-xenserver-powered-openstack-cloud/ Thanks, Bob From: Mardan Raghuwanshi [mailto:mardan.singh at cloudbyte.com] Sent: 10 January 2014 10:21 To: openstack-dev at lists.openstack.org Subject: [openstack-dev] Not able to launch VM From Windows Server 2008 Template.
