Hi,
I the attached picture "net1.jpg" i have my initial network configuration.
Physical card (em1) with vlan 10 (em1.10) bridged to the ovirtmgmt with IP =
192.168.10.25 and default gw 192.168.10.254.
Now i want to bond em1 card with p1p1 card (attached picture net2.jpg)
But if i fill the default gw it gives me this error: The default gateway sh=
ould be set only on engine network.
If i don't fill the default gw, when i click ok, i loose connection to the =
server and then after more or less 1 minute the server automaticaly reboots=
.
Anyone had this kind of problem?
Two thoughts here: ;)
* The "lose connection to the server" bit sort of sounds like
this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=3D838816
Reckon that's a match?
* Aside from that, you might have to manually configure
networking for the hosts from the command line. Using the
normal Linux commands I mean, not oVirt specific ones.
i.e. creating the bridging and everything manually.
This is the approach I had to take last week when trying
out Aeolus with oVirt 3.1. Network layer breaks when
adding a 2nd interface, but was able to work around it
by manually creating the bridges from cli, after having
defined the logical networks in the oVirt Web UI.
The "configure things manually" approach isn't all that
documented either. I kind of stumbled my way through, by
looking at the examples here:
I second that! I just trial and errored my way through bond -> vlan -> brid=
ge. Let=B4s just say that=B4s for people who are up for a challenge. But lu=
ckily, I=B4m one for sharing:
Start by defining to load bonding at boot:
# cat > /etc/modprobe.d/bonding.conf << EOF
alias bond0 bonding
EOF
Then define the bond. This is LACP mode:
# cat > /etc/sysconfig/network-scripts/ifcfg-bond0 << EOF
DEVICE=3Dbond0
NM_CONTROLLED=3Dno
USERCTL=3Dno
BOOTPROTO=3Dnone
BONDING_OPTS=3D"mode=3D4 miimon=3D100"
TYPE=3DEthernet
MTU=3D9000
EOF
Then "enslave" the physical NICs to the bond:
# cat > /etc/sysconfig/network-scripts/ifcfg-em1 << EOF
NM_CONTROLLED=3D"no"
BOOTPROTO=3D"none"
DEVICE=3D"em1"
ONBOOT=3D"yes"
USERCTL=3Dno
MASTER=3Dbond0
SLAVE=3Dyes
EOF
# cat > /etc/sysconfig/network-scripts/ifcfg-em2 << EOF
NM_CONTROLLED=3D"no"
BOOTPROTO=3D"none"
DEVICE=3D"em2"
ONBOOT=3D"yes"
USERCTL=3Dno
MASTER=3Dbond0
SLAVE=3Dyes
EOF
Then create VLAN interfaces ontop of the bond. In this example, I=B4m using=
VLAN ID 1 and 2:
# cat > /etc/sysconfig/network-scripts/ifcfg-bond0.1 << EOF
DEVICE=3Dbond0.1
VLAN=3Dyes
BOOTPROTO=3Dnone
NM_CONTROLLED=3Dno
BRIDGE=3Dbr1
MTU=3D1500
EOF
# cat > /etc/sysconfig/network-scripts/ifcfg-bond0.2 << EOF
DEVICE=3Dbond0.2
VLAN=3Dyes
BOOTPROTO=3Dnone
NM_CONTROLLED=3Dno
BRIDGE=3Dovirtmgmt
MTU=3D9000
EOF
Lastly, create the bridges ontop of the VLAN interfaces. The names, as I ha=
ve understood it, can be whatever you want, but one needs to be called "ovi=
rtmgmt" of course:
# cat > /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt << EOF
TYPE=3DBridge
NM_CONTROLLED=3D"no"
BOOTPROTO=3D"none"
DEVICE=3D"ovirtmgmt"
ONBOOT=3D"yes"
IPADDR=3DXXX.XXX.XXX.XXX
NETMASK=3D255.255.255.0
EOF
# cat > /etc/sysconfig/network-scripts/ifcfg-br0 << EOF
TYPE=3DBridge
NM_CONTROLLED=3D"no"
BOOTPROTO=3D"none"
DEVICE=3D"br0"
ONBOOT=3D"yes"
IPADDR=3DXXX.XXX.XXX.XXX
NETMASK=3D255.255.255.0
EOF
Gateway goes into:
# cat > /etc/sysconfig/network << EOF
GATEWAY=3DXXX.XXX.XXX.XXX
EOF
This way, you can have almost(4096) as many interfaces as you want with onl=
y two physical NICs. I also gave an example on how you tune Jumbo Frames to=
be active on some interfaces, and have regular windows size on the rest. J=
umbo most only be active on interfaces that isn=B4t routed, since the defau=
lt routing size is 1500.

Is any of that helpful?
