Re: [Xen-users] DomU kernel upgrade tool

[Esteban Cerutti <ecerutti@xxxxxxxxxxxxxxxxxxxxxx>]

yes, i did it, but... because my english is poor, i prefer copy and
paste the results below

# depmod 2.6.24-22-xen
WARNING: Couldn't open directory /lib/modules/2.6.24-22-xen: No such
file or directory

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

etc..

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
