Re: [Xen-users] DomU kernel upgrade tool
yes, i did it, but... because my english is poor, i prefer copy and
paste the results below
# depmod 2.6.24-22-xen

but when I try use iptables
# iptables -L
FATAL: Module ip_tables not found.
iptables v1.3.8: can't initialize iptables table `filter': iptables who?
(do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
because there is not the modules files, but instead its are in the
previous kernel version

So, the solution for me was copy modules files from Dom0. But what
happens if i have 40 VMs? I have a headache
Thanks for your replies
