I've created scripts to do that. Should they be included in the repositories
(Ian, Keir)?
Here are they again.

(configure your xend-config.sxp to use them instead of the default ones, place
them at /etc/xen/scripts)

Cheers
Gregor

For those who prefer patching instead of coping the files from the archive the
patchfile is attached to the email.

Gregor, in your xmexample script you have:

vif = [ 'ip=192.168.%d.1/24' % (vmid)]

I have a much simpler config file, which has:

vif = [ 'ip=192.168.2.1/24']

...which I tried to use but I get an error from xm create. Looking at
create.py (xen-unstable) , I don't see a provision to parse assignment
for ip= for vif:

gopts.var('vif', val="mac=MAC,bridge=BRIDGE,script=SCRIPT,backend=DOM",

Am I missing something, or is it possible you are using this on an
unreleased build?

Thanks,

Andrew Theurer

The way the default setup (xmexample) works is as follows:
in domain 0 - vif gets ip = 192.168.vmid.1
in domU - eth0 gets ip = 192.168.vmid.2
this way we can easily update the routing tables in dom0.
There can be up to 255 unprivileged domains (which is plenty).

This way all the virtual interfaces in dom0 would be getting the same ip,
which will not work for more then one domU.

What is the error? Does it happen when you are trying to set up the first
unprivileged domain or any subsequent ones. What IP address do you give to
eth0 in domU?

The whole 'ip=192.168.whatever.1' gets passed to vif-nat script
(/etc/xen/scripts/vif-nat) which then uses it in to bring the vif up.

That should work for both the unstable and testing trees. Maybe you have not
reinstalled the tools, and the vif-nat and network-nat scripts did not get
copied to /etc/xen/scripts? Have you modified xend-config.sxp to use the new
scripts?

OK, that's exactly what I wanted to do.

Actually I have a diferent file for each vmid, generated by bash
scripts, with have a different 192.168.vmid.1, so I think our intent is
the same, just different implemtations. My way was driven by my lack of
python experience :)

I don't have the error recordred, but I think it was a python parsing
error. Perhaps I just didn't get the format correctly. I cannot
reproduce at the moment, because apparantly I have really screwed
somthing up by trying the unstable tree, and so far I have not been able
to get 2.0-testing or 2.0.1 running again (and 2.0.3 has always stuck at
"Scrubbing memory..").

I'll try to get back where I started, 2.0.1 with the error reproduced.
Hopefully it's just an error on my part. Thanks for your help!
