Good day,
I would like to ask for help in setting up bundles bridge over bonding to work with KVM. Idea is this, there are two network interfaces eth0 and eth1 on a machine that is used as a host for virtual machines. Network interfaces connected to the same local network, I would like to set up bonding for load balancing between them.
I'm set up bonding, bridge over it, make bridge as an interface for virtual machines. Result: the host system network is working, even balanced and apparently all is well... But network in the virtual machines dosn't work.
So, configs:
Diagnostics with tcpdump showed that the packets go from virtual machines in a network, but do not come back. DHCP requests to observe the following: DHCP Request to see vnet0, vbr0, bond0 eth0 or eth1, DHCP reply to see eth0 or eth1, bond0, vbr0, but on vnet0 not see :(
I tried to do:[list type = decimal]
[li] Add vlan-raw-device bond0 herein vbr0 and replace bridge_ports bond0 on bridge_ports bond0.11 or bond.10 [/li]
[li] Enable and disable STP [/li]
[li] A lot of google and read about the bugs in the incorrect processing arp bugtracker Ubuntu and redhata [/li]
[li] To learn Japanese [/li][/list]
Unfortunately nothing of the above did not help me. Perhaps someone more experienced tell me what is the problem?
Thank you in advance for your help.
