A vnic can be defined on a network (using vnic profiles).

Re: [ovirt-users] NetworkManager with oVirt version 4.2.0
I had these types of issues as well my first time around, and after a failed engine install I haven't been able to get things cleaned up, so I will have to start over. I created a bonded interface on the host before the engine setup. but once I created my first VM and assigned bond0 to it, the engine became inaccessible the moment the VM got an IP from the router. What is the preferred way to setup bonded interfaces? In Cockpit or nmcli before hosted engine setup? Or proceed with only one interface then add the other in engine? Is it possible, for example, to setup bonded interfaces with a static management IP on vlan 50 to access the engine, and let the other VMs grab DHCP IPs on vlan 10?

Re: [ovirt-users] NetworkManager with oVirt version 4.2.0
I think that I find a quick workaround to resolve this issue, I remove all the logical interfaces from NM and from sysconfig/network-scripts and restart the server, the VDSM service generates the new file and configuration and everything works as cream. 1. delete all the ifcfg-* files from /etc/sysconfig/network-scripts (except for the ifcfg-lo ) 2. delete the interfaces from NetworkManager as follow: nmcli d delete ovirtmgmt nmcli d delete bond0 nmcli d delete bond0.1 👍 On Sun, Feb 4, 2018 at 10:42 AM, Edward Haas wrote: > You may be encountering this problem: https://bugzilla.redhat.com/ > show_bug.cgi?id=1523661 > If this is it, you have two options: > - Upgrade VDSM to latest 4.2.1. > - Define first the VLAN on one of the slaves, add the host to Engine and > then modify the network attachment by creating a bond through Engine. > > Thanks, > Edy. > > On Sun, Feb 4, 2018 at 9:30 AM, Edward Haas wrote: > >> >> >> On Sat, Feb 3, 2018 at 9:06 AM, maoz zadok wrote: >> >>> Hello All, >>> I'm new to oVirt, I'm trying with no success to set up the networking on >>> an oVirt 4.2.0 node, and I think I'm missing something. >>> >>> background: >>> interfaces em1-4 is bonded to bond0 >>> VLAN configured on bond0.1 >>> and bridged to ovirtmgmt for the management interface. >>> >>> I'm not sure its updated to version 4.2.0 but I followed this post: >>> https://www.ovirt.org/documentation/how-to/networking/bondin >>> g-vlan-bridge/ >>> >> >> It looks like an old howto, we will need to update or remove it. >> >> >>> >>> with this setting, the NetworkManager keep starting up on reboot, >>> and the interfaces are not managed by oVirt (and the nice traffic graphs >>> are not shown). >>> >> >> For the interfaces to be owned by oVirt, you will need to add the host to >> Engine. >> So I would just configure everything up to the VLAN (slaves, bond, VLAN) >> with NetworkManager prior to adding it to Engine.

Re: [ovirt-users] NetworkManager with oVirt version 4.2.0
You may be encountering this problem: https://bugzilla.redhat.com/show_bug.cgi?id=1523661 If this is it, you have two options: - Upgrade VDSM to latest 4.2.1. - Define first the VLAN on one of the slaves, add the host to Engine and then modify the network attachment by creating a bond through Engine. Thanks, Edy.

[ovirt-users] NetworkManager with oVirt version 4.2.0
Hello All, I'm new to oVirt, I'm trying with no success to set up the networking on an oVirt 4.2.0 node, and I think I'm missing something. background: interfaces em1-4 is bonded to bond0 VLAN configured on bond0.1 and bridged to ovirtmgmt for the management interface. I'm not sure its updated to version 4.2.0 but I followed this post: https://www.ovirt.org/documentation/how-to/networking/bonding-vlan-bridge/ with this setting, the NetworkManager keep starting up on reboot, and the interfaces are not managed by oVirt (and the nice traffic graphs are not shown). my question: Is NetworkManager need to be disabled as in the above post? Do I need to manage the networking using (nmtui) NetworkManager? Thanks! Maoz ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
