Depends on the kind of OS you want to run, the virtualization tools you
want to use (Xen, KVM, QEMU, VMWare, ...) and the typical use case
(server, workstation, ...). You can use Xen without VT/HVM for example,
but this will require paravirtualized guests (Linux, NetBSD and Solaris
meet this criteria so far, and IIRC recent versions of FreeBSD too).
-1. Is it necessary to have VT technologie in the processeur ?
-2. Is it necessary to have a modified file/kernell to install it in
the VM ?
In case of paravirtualization, yes. With hardware virtualization, most
-3. How many VM can we build ? (15 would be good for me)
As many as you want, provided you have enough ressource for that.
-4. Does th server need to be a SMP, or a quad core single proc, or a
bi quad core ?
Does not matter.
Again, it depends on the kind of OS you want to virtualize. I have
NetBSD domains with around 30MB, just to run some services (like a small
DHCP server), and other domains with 512MB to run "lightweight" (meh)
Java apps together with their GUI.
-5. What is the minimum ram for each VM ?
Without more details, it is rather hard to tell.
