Yes! This VM act as L2 VPN server. Inside the VM tap device is bridged with vm lan adapter. This should work, so let me ask some detailed questions: Does the issue reproduce, if you are using a single NIC instead of a bond? Can you please share the output of bridge fdb show br ovirtmgmt and brctl showmacs ovirtmgmt while replacing ovirtmgmt with the name of your bridge? What are relevant MAC addresses like bridge/bond, vNIC and tun device in the output? What is the output of ebtables -t filter -L ? The thread [ovirt-users] DHCP Client in Guest VM does not work on ovirtmgmt https://lists.ovirt.org/archives/list/users@ovirt.org/thread/566IC5K2B2JJ... might be similar. > Exactly as descived in bz1279161 (that's solved in bz1135347 > but it's > not public and I can't read it) > > > Unfortunately BZ1135347 does not look helpful here.
