[Xen-users] Route networking xen 4
Hey guys, I'm facing some issues on route networking. Could someone give me a hand with route networking configuration on xen 4, please?
I just wanna make dom0 communicates with domU by pinging each other, but it doesn't seem to get the network working at all. Ive been stucked on this a week or so!
Here it goes some configuration on my machine - Ubuntu 12.04: first of all, my xen settings: #cat /etc/xen/xend-config.sxp
(logfile /var/log/xen/xend.log)
(loglevel DEBUG)
(xend-unix-server yes)
(network-script network-route)
(vif-script vif-route)
(dom0-min-mem 196)
(total_available_memory 0)
(dom0-cpus 0)
(vncpasswd '')
-
#cat /etc/xen/xenroute.cfg
bootloader = '/usr/lib/xen-default/bin/pygrub'
vcpus = '1'
memory = '526'
root = '/dev/xvda2 ro'
disk = [
'file:/xen/domains/xenroute/disk.img,xvda2,w',
'file:/xen/domains/xenroute/swap.img,xvda1,w',
]
name = 'xenroute'
vif = [ 'ip=10.0.0.1,mac=00:16:3E:1C:4C:D3' ]
>
on_reboot = 'restart'
on_crash = 'restart'

To set up my network I followed this tutorial : http://wiki.kartbuilding.net/index.php/Xen_Networking#Two-way_Routed_Network_2
Any clue?Appreciate your attention! Carol
