Hello, engine f18 3.2 stable. I try to install a host in a new DC where I only configured ovirtmgmt network as vlan tagged with vlan id 65 Install fails with this error in /var/log/ovirt-engine/host-deploy/ovirt-20130307154915-10.4.4.57.log ... 2013-03-07 15:49:15 ERROR otopi.context context._executeMethod:139 Failed to execute stage 'Setup validation': Interface em3.65 is VLAN interface However its configuration is unexpected .. On fedora18 host I have NetworkManger disabled and network enabled. At the moment the only adapter that starts on the system is em3 and its vlan counterpart em3.65, with these conf files: # cat ifcfg-em3 DEVICE=em3 HWADDR=00:1C:C4:AB:89:0F TYPE=Ethernet BOOTPROTO=none IPV6INIT=no UUID=0675d8c1-858e-4819-9c65-4ff5f63587b7 ONBOOT=yes NM_CONTROLLED=no # cat ifcfg-em3.65 DEVICE=em3.65 ONBOOT=yes BOOTPROTO=none VLAN=yes IPADDR=10.4.4.57 NETMASK=255.255.255.0 GATEWAY=10.4.4.250 NM_CONTROLLED=no How should I configure the host at the beginning to have ovirtmgmt configured as VLAN tagged and host deploy with no complain? Thanks in advance, Gianluca
