Thanks for answering, my considerations below.
…
I've observed this behavior in bug https://bugzilla.redhat.com/show_bug.cgi?id=1230638 We also removed all firewall rules, checked iPXE and I also saw the requests going out, but no replies getting to the VM. But here it sounds like it isn't specific to bonds. After all I did not find the solution yet.
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?
It is probably a good idea to install the oS with a static IP, and then switch to dhcp to then use tcpdump inside the vm to see what is reaching the inside.
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. - fabian
