Archive/XCP CloudStack

Introduction

CloudStack (cloud.com) is a mature cloud orchestration technology that works with KVM, VMWare, XenServer, and XCP. CloudStack was acquired by Citrix in 2011, and is the orchestration system of choice for XCP and XenServer.

XCP Compatibility

XCP 1.5

Before installing CloudStack, perform these steps on each XCP host:

1. Rename or copy /etc/xensource/installed-repos/xcp:main to /etc/xensource/installed-repos/xs:main (this name changed between 1.1 and 1.5) to get the CloudStack supplemental pack installed.
2. Fix the get_mtime bug by replacing the NFSSR.py file with a custom built version and actually include the python stats module to get access to the functions necessary.
3. Do not modify the XAPI version as some other HOWTOs suggest. For CloudStack to work the API version should be kept as it is from the install ("1.4.90").
   1. The latest XenCenter will work with XCP 1.5 natively and also does not require modifying the XAPI version.
