Re: [Xen-users] XEN Networking Howto ?

[James Weeks <chiptoxic@xxxxxxxxxxxxx>]

If you are trying to configure your interface with something like yast i 
believe you have to do the following
shutdown all vm's think /etc/init.d/xendomains stop will do that or xm 
shutdown <domain>
then you need to stop your xen networking bridge with the following 
(note this will mean your system is back using eth0 not peth0)
/etc/xen/scripts/network-bridge stop netdev=eth0

do your normal configuration of eth0 with yast, vi or whatever etc now 
like you normaly would then when ready restore your xen bridge again
/etc/xen/scripts/network-bridge start netdev=eth0

and finnaly restore your vm domains either using xm or xendomains

Im still new to xen but i remember doing this when i first started 
learning on suse so think this may help if you need to configure 
interfaces. But im guessing you have another problem as i cant see eth0 
listed or any vif interface linked to your xenbr0 bridge so maybe the 
driver for your network cards not loaded.
But like i say im still new and learning. I think its worth looking to 
make sure your network card driver working as i dont think sit0 is a 
networking device as such. I think its stands for simple internet 
transition and is somthing to do with encapsulating ipv6 in ipv4 
datagrams but this is the first time i seen the sit device so only did a 
very quick google search.
