Description of problem:

After self hosted engine deployment via physical host VLANed interface, host is marked as non operation with following reason:

Host hosted_engine_1 moved to Non-Operational state because interfaces 'em1.172' are down but are needed by networks 'rhevm' in the current cluster

It seems that engine incorrectly detects state of host vlan interface em1.172 (which is UP)

[root@dell-r210ii-07 ~]# ip a l em1.172
16: em1.172@em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP 
    link/ether d0:67:e5:f0:82:44 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::d267:e5ff:fef0:8244/64 scope link 
       valid_lft forever preferred_lft forever


Version-Release number of selected component (if applicable):
Red Hat Enterprise Virtualization Manager Version: 3.4.1-0.28.el6ev
ovirt-hosted-engine-setup-1.1.3-2.el6ev.noarch

Steps to Reproduce:
1. configure VLAN on host
cat > ifcfg-em1 << EOF
DEVICE=em1
ONBOOT=yes
BOOTPROTO=none
NM_CONTROLLED=no
EOF

cat > ifcfg-em1.172 << EOF
DEVICE=em1.172
VLAN=yes
BOOTPROTO=dhcp
ONBOOT=yes
NM_CONTROLLED=no
EOF

2. yum install ovirt-hosted-engine-setup 
3. screen hosted-engine --deploy 
4. and choose interface em1.172 for deployment
5. finish self hosted engine deployment
6. log in  webadmin

Actual results:
incorrect detection of physical hosts VLAN interface state

Expected results:
correct detection of physical hosts VLAN interface state

Interesting, there seems to be no interface-related data. Dan, any idea why that could be? I see a couple of errors on the vdsm and supervdsm logs, not sure which of them are pertinent (there's one specifically about stat-fetching).

There's no info regarding networking AT ALL.

I suspect that vdsm and vdsm-python have misfitting versions, despite an explicit requirement. What is `rpm -qa vdsm*` on the host?

[root@dell-r210ii-07 ~]# rpm -qa vdsm*
vdsm-4.14.7-7.el6ev.x86_64
vdsm-python-zombiereaper-4.14.7-7.el6ev.noarch
vdsm-python-4.14.7-7.el6ev.x86_64
vdsm-cli-4.14.7-7.el6ev.noarch
vdsm-xmlrpc-4.14.7-7.el6ev.noarch

And what's `rpm -V vdsm-python`?
Can you see vlanSpeed in /usr/lib64/python2.6/site-packages/vdsm/netinfo.py ?
