Hi,

The easiest way to install on a different arch is get the source
packages and rebuild for your arch.

For centos5, the source packages you need are:

http://lisa.ines.ro/download/lisa/rpm/centos/5/lisa-2.0.1_2.6.18-1.el5/lisa-2.0.1_2.6.18-1.el5.src.rpm
http://lisa.ines.ro/download/lisa/rpm/centos/5/kernel-2.6.18-128.1.10.el5.lisa2.0.1/kernel-2.6.18-128.1.10.el5.lisa2.0.1.src.rpm

See the "prerequisites" section in our rpm howto to setup your build
environment:
http://lisa.ines.ro/wiki/doku.php?id=building_packages#prerequisites

You can get the mkrpmbtree.sh script directly from our git web
interface:
http://lisa.ines.ro/git/lisa/blob/?id=668079a958ffc47a57267db98897e2f07323fff4

I've never built x86_64, but I assume you need an additional line in
this script:

mkdir RPMS/x86_64

or run it directly in the shell.

Now you're ready to build. Use the following:

rpmbuild --rebuild lisa-2.0.1_2.6.18-1.el5.src.rpm
rpmbuild --target x86_64 --without kabichk kernel-2.6.18-128.1.10.el5.lisa2.0.1.src.rpm

The answers to the other two questions of yours:

1. It is possible to install LiSA in a xen guest (aka domU), but you'll
need a kernel that contains both the xen and the LiSA patch. On centos
you'll get one by default, if you rebuild the LiSA kernel .src.rpm (as
explained above).

However, LiSA was meant to run in the host (aka dom0) as an alternative
solution to the (standard) linux bridge for providing network
connectivity to guest VMs.

2. I'm aware of the vyatta project, and there's also another project
that allows you to run the original Cisco IOS in a virtual machine (I
don't remember the project name now) and have virtual (ethernet)
interfaces in the host hardwired to the interfaces in the VM.

Vyatta is a full-featured and mature project (they also sell custom
hardware afaik) with maximum performance (in packet processing /
throughput), but is 0% Cisco-like.

The Cisco/IOS emmulator is 100% Cisco-like (because it actually runs
their software), but is has low performance due to emmulation.

LiSA is somewhere in the middle and is ideal for those who want decent
performance, cheap hardware and a Cisco-like interface.

Depending on your your requirements, you may want to consider looking at
either Vyatta or the IOS emmulator. BTW, there's also a project named
xorp (http://www.xorp.org/) but I've had headaches trying to set it up.

Best,

Radu
