Hi Aleksi,
These are indeed good ideas.
The 1st solution is not feasible in my case as I am stuck with an
existing implementation.
But regarding the 2nd solution, I am wondering how vmware and xen
are able to offer a unique MAC address to each virtual OS.
I mean, what address space do these come from?
What happens if they need to host a large number of virtual OSes,
do they pre-allocate these, any ideas?
Thanks & Regards
Vijay
