simply start the vm with old code and new code. (I have reboot the host to be sure)
can't ping the vm with new code.
But it's work fine with kernel 3.7.

Maybe, I'll do test without bond.
It's really possible it's a kernel problem, because like I said it, a lot of work has been done in kernel around 2.6.39 on the vlan code.

Hi,
Urgh... that's pretty sad. It was working fine my test. But maybe i
didn't test everything. Could you desribe me how exactly you've done the
test?
I've no bond running - just plain eth => bridge. Maybe that's the
important difference?
