By the way, what are the exact steps to add a new network in oVirt? Because I was following this guide
https://www.ovirt.org/documentation/how-to/networking/bonding-vlan-bridge/ that basically explains how to create manually a standard bond+vlan+bridge, that I already did on my ovirt hosts, but I can't manage to get the network working in the VMs. Ovirt always complains about that the network is not available on that host. I created a network named "br20" in my case. My ifcfg-* files: [root@vm04 network-scripts]# cat ifcfg-bond0.20 DEVICE=bond0.20 VLAN=yes BOOTPROTO=none NM_CONTROLLED=no BRIDGE=br20 MTU=1500 [root@vm04 network-scripts]# cat ifcfg-br20 TYPE=Bridge NM_CONTROLLED="no" BOOTPROTO="none" DEVICE="br20" IPADDR=192.168.9.228 NETMASK=255.255.255.0 ONBOOT="yes" DEFROUTE=no What am I missing? 2016-09-21 7:53 GMT+02:00 Edward Haas <eh...@redhat.com>: > > > On Tue, Sep 20, 2016 at 12:13 PM, Maxence Sartiaux <cont...@makz.me> > wrote: > >> Okay, i found a workaround. >> >> - Create empty ifcfg-lan on all hosts (touch >> /etc/sysconfig/network-scripts/ifcfg-lan) >> - Assign the bridge to the bond (Ovirt only add MTU=1500 in the file) >> - Unassign the bridge (Ovirt rewrite the bond configuration files) >> - Re-assign the bridge on the bond >> - yay it work ! >> > > I would recommend describing the exact steps you do, provide output of the > ifcfg list of files at each step + vdsm and supervdsm logs. > > I am not clear what is the 'lan' device is representing, is this your bond > name? > network name? > > > >> >> On Tue, 2016-09-20 at 10:08 +0200, Maxence Sartiaux wrote: >> >> I configured the bond manually by editing the ifcfg file like i did in >> my old install on ovirt 3.6 and 4.0 >> >> the only ifcfg file i have are the 4 for the physical interfaces, two >> for the bonds and one for the ovirtmgmt bridge. >> >> I'll send the vdsm log later. >> >> On Mon, 2016-09-19 at 10:14 -0400, Francesco Romani wrote: >> >> >> From: "Maxence Sartiaux" <cont...@makz.me> >> To: "users" <users@ovirt.org> >> Sent: Monday, September 19, 2016 11:53:12 AM >> Subject: [ovirt-users] Can't add logical network >> >> Hello, >> >> On a clean install ovirt 4.0.3-1, i've configured my bond on my >> hypervisor, created a new network on the engine and now i try to >> assign the logical network to my bond in the host network settings. >> >> When i save the configuration, the engine throw me an error and the >> following event >> >> VDSM hypervisor1 command failed: [Errno 2] No such file or directory: >> u'/etc/sysconfig/network-scripts/ifcfg-lan' >> >> if i "touch" the file manually i don't have this error but my file >> only contain "MTU=1500" nothing more. >> >> Engine bug or i miss something ? >> >> How you configured the bond on your hypervisor? >> Seems like Vdsm doesn't like your changes, perhaps it cannot just >> identify the interface configuration >> >> Edward, do you have any recommendations about this flow? >> >> -- >> Francesco Romani >> RedHat Engineering Virtualization R & D >> Phone: 8261328 >> IRC: fromani >> >> _______________________________________________ >> Users mailing list >> Users@ovirt.org >> http://lists.ovirt.org/mailman/listinfo/users >> >> >> _______________________________________________ >> Users mailing list >> Users@ovirt.org >> http://lists.ovirt.org/mailman/listinfo/users >> >> > > _______________________________________________ > Users mailing list > Users@ovirt.org > http://lists.ovirt.org/mailman/listinfo/users > > -- Davide Ferrari Senior Systems Engineer
