I've been struggling to get xen going on FC5 ever since I upgrade a
machine from FC4 to FC5 and xen 2 to xen 3.
The machine seems to work fine, including creating guests and the virtual
interfaces. Networking is fine, etc.
But, when I use iptables (via Shorewall), I get a kernel panic almost
immediately when attempting network IO. If I ssh into the box, it will
take a few screeens of data before panicing. If I connect to the samba
server on the machine from a windows client, the panic is immediate.
I've tried loading netbk, blkbk, and netloop in the initrd. I've tried
building all of the iptables modules into the kernel. So far, I'm unable
to use iptables/shorewall without a panic.
I don't have a serial terminal connected, so I haven't captured the xen
output, but it looks similar to other network panics I've seen on this
list. Something like "kernel not syncing" and something about an
interrupt.
kernel and xen versions are:
2.6.17-1.2174_FC5xen0 #1 SMP Tue Aug 8 17:03:19 EDT 2006 i686 athlon i386
GNU/Linux
xen-3.0.2-3.FC5
These are packages from the standard FC5 rpms.
Any ideas?
My list of modules with and without iptables is below:
