[ovirt-users] Re: trunked ports

You should be able to use bonded interfaces with an IP on each VLAN Interface for the ovirt hosts and the engine. For example, here is the IP configuration for one of our VLANs. 10: bond3: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 00:1b:21:5c:80:39 brd ff:ff:ff:ff:ff:ff inet6 fe80::21b:21ff:fe5c:8039/64 scope link valid_lft forever preferred_lft forever 24: bond3.311@bond3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 00:1b:21:5c:80:39 brd ff:ff:ff:ff:ff:ff inet 192.168.111.201/24 brd 192.168.111.255 scope global bond3.311 valid_lft forever preferred_lft forever inet6 fe80::21b:21ff:fe5c:8039/64 scope link valid_lft forever preferred_lft forever bond3.311 configuration is managed in the /etc/sysconfig/network-scripts/ifcfg-bond3.311 file. IMO setting up bonded NICs with VLAN tagging is one area where ovirt falls short. You essentially have to configure your networks twice. First using the /etc/sysconfig/network-interface files and then inside of the engine itself.

VDSM may also need to be configured to use ifcfg persistence in the config file. cat files/vdsm/vdsm.conf [vars] ssl = true net_persistence = ifcfg The ifcfg persistence mode is planned for deprecation in 4.3, and is not

[addresses] management_port = 54321 Your switch ports also need to be configured to support 802.1q networking.

I have deployed with Gluster, and am now moving on to networking. I come from a VMware shop and normally we trunk all the network ports exposing all VLANs to the hosts and place VMs in Portgoups that are tagged with VLANs. I did manage to do this years back but I am struggling to get this to work today. I had pretty limited hardware back then and I thought I installed using vlan tagging and trunked ports, but I don’t see any option to do this using the glusterfs and hosted engine setup. Each host has a dual port 10Gb NICs I use one for storage that is connected to my storage network and one for ovirtmgmt. (I need to add another of these for redundancy down the road, but no money for that at the moment) The hosts also have 4 x 1Gb ports. So in lieu of being able to configure vlan tagging to trunked ports on hosted engine deploy, I am considering cabling up a 1 Gb port on each in my management services VLAN and when it is all up and running create another logical network (or several of them as I think these equate to what is a vlan tagged port group in VMware) with the 10Gb NIC backing for VMs. Does that sound reasonable? Or if anyone can point me to any docs that describe how to deploy to a specific VLAN with trunk ports, that would be nice as well as I won’t have to actually go to the office and run additional cables.
