Hi Javier,
Further to my late posting;
After installing udev on next boot the guest was completely cut off
from outside world. It can't be ssh-connected remotely. After
starting it with "xm console ....." it can't ping the host, other
guests and Internet.
# /etc/init.d/networking restart
Reconfiguring network interfaces...SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
eth0: ERROR while getting interface flags: No such device
Failed to bring up eth0.
# find /sys -iname *eth*
/sys/class/net/eth5
/sys/devices/xen/vif-0/net:eth5
I was compelled to remove udev.
# apt-get remove udev
# rm -rf /etc/udev
# rm /etc/init.d/udev
# reboot
Then it returns normal. I think the guests must run dynamic MAC
address.
B.R.
