I send new mail about this bug with details as required by George Dunlap.
Dom0 is Wheezy 64 bit with kernel from package linux-image-3.2.0-4-amd64
version 3.2.41-2, package blktap-dkms and all dependency packages for
xen, spice and usb redirection.
xen.git (in this build commit is 96ef6e88359910738905ac2e1969dc05d7d7e7dc)

Other details about dom0 installation see here:

DomU is Windows 7 pro 64 bit with gplpv build 372 debug.

After restore it sees network but is not working, nor lan neither wan.
Tried with both dhcp and static ip, try also e1000 network card, tried
also qemu 1.4.
Is the vif device present and on the bridge in dom0? What about the emu

Can you post the output of "xenstore-ls -fp" please.

I notice references to openvswitch in your logs -- which script are you
using, the one I recently posted or something else?


Thanks for reply, the vif and the vif -emu are present, bridge also and
is working.
Are the both the vif* present on the bridge? What does "ovs-vsctl show"

On attachment logs of save, restore, copy of vif and xenstore command
you told me, both before and after save/restore.
Thanks, I can see that the front and backend devices are connected ok
and appear to be happy and the hotplug scripts were successful.

However I did notice that the device MAC address seems to have changed!
I can believe this could confuse things...

Does this issue go away if you specify
in your configuration?


Thanks, fixed mac solve the problem.
Is possible solve for have network working after restore without mac on xl configuration file also on qemu upstream? The last test was without openvswitch, I must redo with it and post "ovs-vsctl show" result?
