The Ethernet virtual device of my DomU doesn't seems to load and I can't explain why.
Dom0 : Debian Wheezy with Xen
uname -r : 3.2.0-4-amd64

One Working DomU
I have 1 x fresh DomU (wheezy), installed with "xen-create-image", working perfectly. When I do a dmesg on this DomU, we can see inside : "Initialising Xen virtual ethernet driver"
Failing DomU (the problem)
But another existing DomU (that I want to migrate from an old Dom0 to the new one), also a Debian wheezy, seems to be not working. Network is not loaded :
/etc/init.d/networking restart [warn] Running /etc/init.d/networking restart is deprecated because it may not re-enable some interfaces ... (warning). [....] Reconfiguring network interfaces...Cannot find device "eth0" Failed to bring up eth0.
When I do a dmesg on this failing box, the "Initialising Xen virtual ethernet driver" is NOT inside.
(I don't know what other information I can provide ?)
