It's a big problem for me if you create a virtual network with 100 hosts (30MB per host) you need 3 Go per host!! I think this is the disadvantage of xen

Thats not possible, you'll need at least 664MB + 32 MB for the
hypervisor + some overhead, xen won't use exactly 30MB but a little bit
more.

one thing: if you want to use the thing to simmulate some network
behaviour: xen currently supports only 3 virtual interfaces per domU,
that cripples my virtual network as well.

Hi,

I'd like to create a virtual network with xen who have more tha 20
hosts. Every host has 30MB in his configuration file. The total of
memory is

20X30 = 600MB

+

64MB for the dom0
--------------------------
= 664MB

but I only have 512MB on my workstation. Can this virtual network
possible with xen? Or you need to have enough ram!?

Thank you
