Ovirt Node NG 4.0.0 wants to bridge my infiniband link
Hi list, I'm trying a test installation of the new Ovirt Node Image and engine before upgrading my 3.6 installation. In my current environment every hypervisor access the NFS shared data domain via infiniband. With a couple of vdsm hooks I was able to set the infiniband link in connected mode and set a MTU of 65520. In my case the infiniband link is used as a common NIC, I don't use RDMA, only IP over infiniband to access the data domain. Now, when I attempt to setup host networking, the system try to bridge the connection "ibstorage" (defined in networks tab) with ib0 device. But a non ethernet device cannot be bridged that way and host networking setup fails. Any idea or suggestion? With 3.6 (node and engine) all was fine.

Hello, What's "couple of vdsm hooks"? Could you provide the source code of those? Regards, Yevgeny On Mon, Jul 4, 2016 at 1:43 PM, Giorgio Biacchi <giorgio@di.unimi.it> wrote:

Hi, hooks are only needed to set connected mode and the correct MTU on the infiniband link. The problem is bound to the host networking setup procedure. Here's the hooks: cat /usr/libexec/vdsm/hooks/before_vdsm_start/10_set_ib0_connected_mode #!/bin/sh echo Setting IB connected mode echo connected > /sys/class/net/ib0/mode sleep 3 MODE=$(cat /sys/class/net/ib0/mode) RATE=$(cat /sys/class/infiniband/mlx4_0/ports/1/rate) echo ib0 is now in $MODE mode with rate $RATE cat /usr/libexec/vdsm/hooks/after_network_setup/10_set_ib0_connected_mode #!/bin/sh echo connected > /sys/class/net/ib0/mode sleep 3 ip link set mtu 65520 dev ib0 As you can see they work: [root@node]# systemctl restart vdsmd [root@node]# ip l sh dev ib0 5: ib0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 65520 qdisc pfifo_fast state UP mode DEFAULT qlen 256 link/infiniband 80:00:02:08:fe:80:00:00:00:00:00:00:00:02:c9:03:00:0a:08:c7 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff [root@node]# cat /sys/class/net/ib0/mode connected In networks tab in the admin portal I've defined a logical network ibstorage with the correct MTU. When I attempt to setup host networking vdsm generates the ibstorage device and a config to bridge it with ib0 but ib0 is not an ethernet device so it cannot be bridged. With 3.6 the configuration was directly applied to ib0 without any bridge. Thanks On 07/04/2016 02:58 PM, Yevgeny Zaspitsky wrote:

As I said, Infiniband is not ethernet so it cannot be L2 bridged. This is normal and I understand why it can't be done. I'd like to know if there's a way to configure host networking for infiniband link without bridging because is not necessary to have a bridge there. In addition to this, 3.6 behavior was different. Here's all the relevant configuration files generated by 3.6 and 4.0: ------------- 3.6 --------------- [root@node3.6]# cat /etc/sysconfig/network-scripts/ifcfg-ib0 # Generated by VDSM version 4.17.11-7.gitc0752ac.el7 DEVICE=ib0 HWADDR=80:00:00:48:fe:80:00:00:00:00:00:00:00:02:c9:03:00:0a:06:9f ONBOOT=yes BOOTPROTO=dhcp MTU=65520 DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no [root@node3.6]# cat /var/lib/vdsm/persistence/netconf/nets/ibstorage { "nic": "ib0", "bootproto": "dhcp", "blockingdhcp": true, "bridged": "false", "mtu": "65520" } --------------------------------- ------------- 4.0 --------------- [root@node4.0]# cat /etc/sysconfig/network-scripts/ifcfg-ib0 # Generated by VDSM version 4.18.5.1-1.el7.centos DEVICE=ib0 BRIDGE=ibstorage ONBOOT=yes MTU=65520 NM_CONTROLLED=no IPV6INIT=no [root@node4.0]# cat /var/lib/vdsm/persistence/netconf/nets/ibstorage { "ipv6autoconf": false, "nic": "ib0", "mtu": 65520, "switch": "legacy", "dhcpv6": false, "stp": false, "bridged": true, "defaultRoute": false } [root@node4.0]# cat /var/lib/vdsm/persistence/netconf/nets/ib0 { "ipv6autoconf": false, "nic": "ib0", "mtu": 65520, "switch": "legacy", "dhcpv6": false, "stp": false, "bridged": true, "defaultRoute": false } [root@node4.0]# cat /etc/sysconfig/network-scripts/ifcfg-ibstorage # Generated by VDSM version 4.18.5.1-1.el7.centos DEVICE=ibstorage TYPE=Bridge DELAY=0 STP=off ONBOOT=yes DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no MTU=65520 --------------------------------- So it seems that 4.0 generates more files and wants to bridge an ethernet unbridgeable link.

Infiniband should not be bridged. Ovirt tries to build a bridge over a NIC if the network is a VM one. Please verify that it isn't. On Mon, Jul 4, 2016 at 5:10 PM, Giorgio Biacchi <giorgio@di.unimi.it> wrote:
