I believe that this issue is due to code introduced by dreyou. http://www.dreyou.org/ovirt/vdsm32.patch diff --git a/vdsm/configNetwork.py b/vdsm/configNetwork.py index 53debfa..c8a80f1 100755 --- a/vdsm/configNetwork.py +++ b/vdsm/configNetwork.py @@ -873,6 +873,11 @@ def addNetwork(network, vlan=None, bonding=None, nics=None, ipaddr=None, _netinfo = netinfo.NetInfo() bridged = utils.tobool(bridged) + # Hack here, netmask may be not defined, if this happen, + # set netmask to 255.255.255.0 + if not netmask: + netmask = "255.255.255.0" + if mtu: mtu = int(mtu) I do not know the motivation for it - I hope that Dreyou himself can help. Dreyou, others - I would very much appreciate it if you send such patches to upstream gerrit.ovirt.org. They deserve discussion and hopefully - incorporation into mainline vdsm. > I've added my notes to https://bugzilla.redhat.com/show_bug.cgi?id=911957 > > > Yuriy Demchenko > > On 02/26/2013 12:37 PM, Yuriy Demchenko wrote: >> Hi, >> >> I'm testing ovirt 3.2 on centos 6.3 (from dreyou repo) and have a >> problems setting up networks: >> 1. >> - clean install of ovirt-engine, added a host (6 NICs, only 1 >> configured with static ip before adding it to ovirt) >> - set up bonding for ovirtmgmt from 2 NICs - em1+em2 >> - set up 2 additional networks ("trunk" with no vlanid, "vlan50" >> with vlanid=50), attached it to cluster >> - trying to set up host networks - assigned "trunk" to one of >> unused NIC, "vlan50" to another, boot protocol in both - "none" >> and when i'm trying to apply changes - i get "Specified netmask or >> gateway but not ip" >> What is wrong? why the hell it thinks i pass some netmask/gw in >> first place?

It is fixed by http://gerrit.ovirt.org/12447 and deseves a rebuild of vdsm. Please confirm that my patch solves this issue.
