Who needs ISO for Citrix Provisioning Services?

Written by Ingmar Verheij on February 5th, 2013. Posted in Provisioning Server

In a previous article I wrote that for streaming vDisks to endpoint you don’t necessarily need PXE, you can also attach an ISO to the virtual machine (“Who needs PXE for Citrix Provisioning Services?”). Although this eliminates the dependency for a PXE server (which is challenging to make high available), mounting an ISO file to the CD rom of a virtual machine creates another problem in some hypervisors.

When a hypervisor host needs maintenance a (storage) vMotion is a good way of moving all systems with no downtime. Mounting an ISO file breaks the ability to vMotion with some hypervisors.

Citrix XenServer and VMware vSphere 5 (Hyper-V I’m not sure of) can mount ISO files from shared storage, so this does not apply to all situations.

Fortunately the bootstrap can also be placed on a virtual hard disk (VHD). In this article I’ll guide you step-by-step how this is done. In this example I’m using VMware vSphere 5 but most steps are equal for other hypervisors.
