Hi,

I have configured that in the HOST machine.

the virtual machine hasn´t that variable. In not running a xen kernel on it?
perhaps thats de problem?

# uname -a
Linux mailserver 2.6.18-92.el5 #1 SMP Tue Apr 29 13:16:15 EDT 2008 x86_64
x86_64 x86_64 GNU/Linux

ls /proc/sys

dr-xr-xr-x 2 root root 0 may 13 19:43 abi
