RE: [Xen-devel] FW: HXEN on linux

["Deepak Kr. Sharma - ERS, HCL Tech" <deepak.s@xxxxxxx>]

Hello Konrad,

We are part of COE team and our priorities are driven by team that does 
technology tracking (mix of sales and delivery). As recommended by them, Xen is 
type-1 hypervisor and HXen is a type-2 hypervisor. Virtualization in a product 
is a value-add service and not the core product functionality. No one would 
want to touch a stable system (which is a must in case of type-1 hypervisor) 
for a value-add service. Hence, HXen gives flexibility to add features on VM 
w/o impacting product's core functionality. The biggest benefit with HXen is 
that it can be ported to any other OS without any changes to the stable system.

Please let me know in case you have any other questions.

I would appreciate your and others' inputs and guidance on the analysis that I 
had sent last week.

Regards,
Deepak

"good solutions" .. such as? I am just trying to wrap my mind
around why you would do this extra work instead of doing it in the Xen 
hypervisor
and expanding what it can do?
