It's not certain that this will be implemented for the XenAPI driver.
Our view is that the BIOS strings shouldn't be relied upon - the hypervisor can clearly set them to anything so it's not really a reliable way to configure the application. Also note that in some scenarios, such as PV guests in Xen clouds, you will not have any BIOS to query. Finally we're not clear on the use case here - What's the use case for needing to know whether you VM is running under OpenStack or not?

In a KVM instantiated VM the following signature is present in the BIOS of the VM
The 'Manufacturer ' field in 'System Information' group is set to "OpenStack Foundation"
This helps the VM to identify that it is getting used in an OpenStack environment.
As far as I know XenServer is planning to set the BIOS Strings in IceHouse release.
Is this functionality available in other Hypervisors, especially Hyper-V & ESX?
