I'm trying to get a 3.6.1 HE setup going where I have 4 VLANs (VIDs 101-104) for storage networks, 1 VLAN (VID 100) for ovirtmgmt and 1 more (VID 1) for everything else. Because I know of no way to manipulate the network configuration from the management GUI once the HE is running and with only a single Host, I made the OS configuration as close as possible to what I'd want when done. This looks like:
Why do you think of this necessary pre-work? I configured (in 3.6.0) an environment with HE too on a single host and I only preconfigured my bond1 in 802.3ad mode with the interfaces I planned to use for ovirtmgmt and I left the other interfaces unconfigured, so that all is not used by Network Manager. During the "hosted-engine --deploy" setup I got this input: --== NETWORK CONFIGURATION ==-- Please indicate a nic to set ovirtmgmt bridge on: (em1, bond1, em2) [em1]: bond1 iptables was detected on your computer, do you wish setup to configure it? (Yes, No)[Yes]: Please indicate a pingable gateway IP address [10.4.168.254]: and then on preview of configuration to apply: --== CONFIGURATION PREVIEW ==-- Bridge interface : bond1 Engine FQDN : ractorshe.mydomain.local Bridge name : ovirtmgmt After setup I configured my vlan based networks for my VMS from the GUI itself as in the usual way, so that now I have this bond0 created by oVirt GUI on the other two interfaces (em1 and em2): [root@ractor ~]# cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: IEEE 802.3ad Dynamic link aggregation Transmit Hash Policy: layer2 (0) MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 802.3ad info LACP rate: fast Min links: 0 Aggregator selection policy (ad_select): stable Active Aggregator Info: Aggregator ID: 2 Number of ports: 2 Actor Key: 17 Partner Key: 8 Partner Mac Address: 00:01:02:03:04:0c Slave Interface: em1 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 00:25:64:ff:0b:f0 Aggregator ID: 2 Slave queue ID: 0 Slave Interface: em2 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 00:25:64:ff:0b:f2 Aggregator ID: 2 Slave queue ID: 0 And then "ip a" command returns: 9: bond0.65@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master vlan65 state UP link/ether 00:25:64:ff:0b:f0 brd ff:ff:ff:ff:ff:ff 10: vlan65: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 00:25:64:ff:0b:f0 brd ff:ff:ff:ff:ff:ff with [root@ractor ~]# brctl show bridge name bridge id STP enabled interfaces ;vdsmdummy; 8000.000000000000 no ovirtmgmt 8000.002564ff0bf4 no bond1 vnet0 vlan65 8000.002564ff0bf0 no bond0.65 vnet1 vnet2 vnet1 and vnet2 being the virtual network interfaces of my two running VMs. The only note I can submit is that by default when you set a network in oVirt GUI with mode=4 (802.3ad), it defaults to configuring it with "lacp_rate=0" so slow, that I think it is bad, as I read in many articles (but I'm not a network guru at all) So that I chose custom mode in the GUI and specified "mode=4 lacp_rate=1" in options and this was reflected in my configuration as you see above in bond0 output. Can we set lacp_rate=1 as a default option for mode=4 in oVirt? HIH, Gianluca
