[pve-devel] new bridge code doesn't work with redhat kernel

[Alexandre DERUMIER]

old config  (bond0.94 is created automaticaly by debian script when adding it to vmbr0)
-----------

auto bond0
iface bond0 inet manual
slaves eth0 eth1
bond_miimon 100
bond_mode active-backup
pre-up ifup eth0 eth1
post-down ifdown eth0 eth1

auto vmbr0
iface vmbr0 inet static
       address 10.3.94.31
       netmask 255.255.255.0
       gateway 10.3.94.1
       bridge_ports bond0.94
       bridge_stp off
       bridge_fd 0

auto vmbr1
iface vmbr1 inet manual
        bridge_ports bond0
        bridge_stp off
        bridge_fd 0



new config
----------
auto bond0
iface bond0 inet manual
slaves eth0 eth1
bond_miimon 100
bond_mode active-backup
pre-up ifup eth0 eth1
post-down ifdown eth0 eth1


auto vmbr1
iface vmbr1 inet manual
        bridge_ports bond0
        bridge_stp off
        bridge_fd 0

auto vmbr1v94
iface vmbr1v94 inet static
        address 10.3.94.31
        netmask 255.255.255.0
        gateway 10.3.94.1
        pre-up brctl addbr vmbr1v94
        pre-up ip link add link vmbr1 name vmbr1.94 type vlan id 94
        pre-up ip link set vmbr1.94 up
        post-up brctl addif vmbr1v94 vmbr1.94




guest vms are using vmbr1 as bridge

Could you please post complete config for example bond0.94 is missing.
