Hi All,
I'm slowly progressing with our test environment and currently I'm testing my
10Ge nics and switches and hit a snag.
I watched the webcast about setting up a non-vm network which included creating a bond
using the webinterface. I can't get it to work correctly.
I have two problems
- my ovirtmgmt network always returns to DHCP in Hosts/Network Interfaces/Setup Host
Networks
- bonding p3p1 and p3p2 into bond0 with mode 4 and assigning an ip address doesn't
work either.
The bond is created but no ip address assigned and I end up with errors in dmesg.
On ST01 I just dropped the bond and restarted the node so I have a clean dmesg.
On ST02 I repeated the bonding but no luck
Host is now Non Responding because of missing network so put it into maintenance.
In Setup Host Networks I create a bond between p3p1 and p3p2, bond name bond0 and mode 4,
edit ovirtmgmt to set it to static instead of DHCP, ip address is correct.
Assign my storage network to the bond, edit its properties and set its ip to Static
172.29.0.1 mask 255.255.255.0. The mouse over popups show the correct ip addresses for
both storage and ovirtmgmt, check Save and Verify, press OK, no ip address on the bond
:-((
ST02 dmesg:
[43523.670576] bonding: unable to update mode of bond3 because it has slaves.
[43523.734204] bonding: bond3: Setting MII monitoring interval to 150.
[43523.736633] 8021q: adding VLAN 0 to HW filter on device bond3
[43534.234245] bond3: no IPv6 routers present
Nothing in engine.log but maybe if logging is set higher, but how??

Nothing on ST01 when I try to create a bond but I do get an error in the mgmt web

Hey,
I was having issues with Node, not being able to create networking "just right",
how I wanted them, so I restarted with plain Fedora and set it up this way:
Services that needs tuning in the beginning:
# systemctl stop NetworkManager.service
# systemctl disable NetworkManager.service
# systemctl start sshd.service
# systemctl enable sshd.service
# systemctl enable network.service
# iptables --flush
# iptables-save > /etc/sysconfig/iptables
# Install yum-priorities, define oVirt repo and install needed packages:
# yum install -y yum-priorities
# cat > /etc/yum.repos.d/ovirt-engine.repo << EOF
[ovirt-engine-3.1]
priority=1
name=ovirt-engine-3.1
baseurl=http://www.ovirt.org/releases/3.1/rpm/Fedora/17/
enabled=1
gpgcheck=0
EOF
# yum upgrade -y
# yum install -y qemu-kvm qemu-kvm-tools vdsm vdsm-cli libjpeg spice-server pixman seabios
qemu-img fence-agents libselinux-python
Now comes networking. 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=bond0
NM_CONTROLLED=no
USERCTL=no
BOOTPROTO=none
BONDING_OPTS="mode=4 miimon=100"
TYPE=Ethernet
MTU=9000
EOF
"Enslave" the physical NICs to the bond:
# cat > /etc/sysconfig/network-scripts/ifcfg-em1 << EOF
NM_CONTROLLED="no"
BOOTPROTO="none"
DEVICE="em1"
ONBOOT="yes"
USERCTL=no
MASTER=bond0
SLAVE=yes
EOF
# cat > /etc/sysconfig/network-scripts/ifcfg-em2 << EOF
NM_CONTROLLED="no"
BOOTPROTO="none"
DEVICE="em2"
ONBOOT="yes"
USERCTL=no
MASTER=bond0
SLAVE=yes
EOF
After that, you create VLAN interfaces ontop of the bond. In this example, I´m using VLAN
ID 1 and 2:
# cat > /etc/sysconfig/network-scripts/ifcfg-bond0.1 << EOF
DEVICE=bond0.1
VLAN=yes
BOOTPROTO=none
NM_CONTROLLED=no
BRIDGE=br1
MTU=1500
EOF
# cat > /etc/sysconfig/network-scripts/ifcfg-bond0.2 << EOF
DEVICE=bond0.2
VLAN=yes
BOOTPROTO=none
NM_CONTROLLED=no
BRIDGE=ovirtmgmt
MTU=9000
EOF
Create the bridges ontop of the VLAN interfaces. The names, as I have understood it, can
be whatever you want, but one needs to be called "ovirtmgmt" of course:
# cat > /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt << EOF
TYPE=Bridge
NM_CONTROLLED="no"
BOOTPROTO="none"
DEVICE="ovirtmgmt"
ONBOOT="yes"
IPADDR=XXX.XXX.XXX.XXX
NETMASK=255.255.255.0
EOF
# cat > /etc/sysconfig/network-scripts/ifcfg-br1 << EOF
TYPE=Bridge
NM_CONTROLLED="no"
BOOTPROTO="none"
DEVICE="br1"
ONBOOT="yes"
IPADDR=XXX.XXX.XXX.XXX
NETMASK=255.255.255.0
EOF
Gateway goes into:
# cat > /etc/sysconfig/network << EOF
GATEWAY=XXX.XXX.XXX.XXX
EOF
Lastly, restart networking and for good measure start ntpd:
# systemctl restart network.service
# systemctl enable ntpd.service
# systemctl start ntpd.service
This way, you can have almost(4096) as many interfaces as you want with only two physical
NICs. I also gave an example on how you tune Jumbo Frames to be active on some interfaces,
and have regular window size on the rest. Jumbo must only be active on interfaces that
isn´t routed, since the default routing size is 1500.
