In our config, I can see the DHCP offer until the hypervisor bridge interface
toward vm
Just to make sure, is your setup:
NIC -- bridge -- VM?
Or is a bond involved?
NICs (two) - BOND (type 4) - VLAN - BRIDGE - VM

Already done. Vm do not acquire the IP address and, on the vm side, tcpdump
shows only requests.
At the same time, the DHCP offer s detected on the bridge if of the
hypervisor.
With static IP, vm works fine.
Yes, it only seems to be around dhcp.
If you don't have a bond involved, then please reopen the bug abaove, and we try to
find
someone to look at it.
