Re: [Xen-users] A classic... Network inside domU

["François Lapointe" <flapointe@xxxxxxxxx>]

Using an (almost) stock xen kernel, here are the modules that load
after xend starts:
bash-3.1$ lsmod
Module                  Size  Used by
tun                    13184  0
xt_physdev              3344  1
loop                   18952  2
iptable_filter          3968  1
ip_tables              15348  1 iptable_filter
x_tables               14468  2 xt_physdev,ip_tables
bridge                 56084  0
