Hypervisor version and XenServer
I'm running through some bugs with my Xen->XenServer work and just ran
across the HYPERVISOR_VERSION being the Xen version and not the XenServer
version. Does anyone know why that is? Given that feature/function in
XenServer is tied to the XenServer version, I see using the Xen version as
a bug waiting to bite us. Since I don't want to break API compatability,
I'm not inclined to change it for this work, but do wonder if we shouldn't
change it when the API revs next.
Thoughts?

I can talk for GuestOSMapping response - HYPERVISOR_VERSION mimics the
behavior in HypervisorCapabilities.
Thanks,

It's an ApiConstant (ApiConstants.HYPERVISOR_VERSION), and is exposed in a
number of places such as the HostForMigration, HypervisorCapabilities and
GuestOSMapping responses. It's set for XenServer in the
XcpServerDiscoverer, and for XenServer 6.2 it really says the hypervisor
version is 4.1.5, not 6.2.0. Once I've gotten everything working in the
Xen->XenServer work, I'll look a bit deeper into how we use it internally
(if at all).

cloud.host table contains hypervisor_version column.
Hopes can help.

Where is this HYPERVISOR_VERSION? In the code? Docs?
