[one-users] hot add or hot plug with OpenNebula?

[Tino Vazquez]

Hi Stefan,

FYI, Jordi Guijarro, from CESCA, wrote me offline to point me out a
nice feature present in Xen 4.0

RAS features: physical cpu/memory hotplug   ( from [1] ).

We definitely hold this in mind for future releases.

Regards,

-Tino
