Xen users - Jul 2009 - Xen configuration file?

Hey guys,

This should be quick.

In most blog posts, and even Steven''s PDF here ( 
http://www.xen.org/files/Support/XenConfigurationDetails.pdf ) everyone 
references these config files, where do those get created in 3.4?

I have a file here:

/var/lib/xend/domains/a90f2411-6047-1589-ff79-da0c3046d607/config.sxp

But it''s syntax is WAY different than anything like in that PDF so I 
figured it is a different file. I am trying to follow this guide here ( 
http://idolinux.blogspot.com/2008/08/xen-add-network-bridge-for-eth1.html ), 
to add a second NIC but I don''t have any files located in the 
/etc/xen/auto directory, or any file resembling the syntax found there.

Do I indeed edit the config.sxp file? If so, what does the syntax look 
like to add another vif device?

Config files (usually on /etc/xen) can use either format. When using
sxp format, you need to add "-F" to "xm create" or "xm
new".

When the config file is located there, it means the domain is managed
by xend. That''s what would happen if you use "xm new", or use
virt-install on newer xen versions. To change the configuration you
should either:
- use commands that can edit configuration online, like "xm
network-attach" (see "man xm" for details), OR
- shutdown the domU, export it''s config file (or copy the config.sxp
somewhere else), delete the domU (xm delete), edit config file, import
the domU (xm new), OR
- shutdown domU, edit config.sxp, restart xend, start domU (not recommended)
