Re: [Xen-users] Re: HVM domU Solaris 10 (Marc Patino G?mez)

Hi list,

i've been wondering the same thing as Marc Patino above, 
i have been building Intel boxes up until now, especially with the multicore Intels being quite cheap.
can anyone confirm that a new large box, meant to run paravirt and hvm, AMD would be the better choice ?
i think real mode HVM would be very interesting to have.
does anyone know where to find more info on this ?

Thanks,
Sven

Hi again Joe,

so.. in your opinion AMD processors are better to make h/w
virtualization? I am planing to buy a "big server" (4 ways) to host
multiple Windows domU and of course I want the most convenient CPUs for it.

Thanks in advance,

Marc
