[quote]the ultimate goal being to make this new socket family

That was from vmware.
If somebody will make something generic, to please xen, kvm, vmware,
and others in an 15 to 20 years time...
Then a tool like this will be accepted ?

Linus, you know this tool was only for x86.
Now if you look at this:
https://github.com/penberg/linux-kvm/commit/051bdb63879385e12b7e253b72cdde909a5e0b9b
There are other platforms added.
Look here: https://wiki.linaro.org/LEG/Engineering/Virtualization
[quote]kvmtool is used meanwhile[/quote]
They are using it !
