[Users] hosted engine setup (network)

[René Koch]

Hi,

During hosted engine setup I faced issues with network configuration on 
my CentOS 6.5 hosts:

My network setup was the following which doesn't work with hosted engine 
setup:
- eth0.200 (VLAN tag 200) should become ovirtmgmt interface
- GATEWAY is in /etc/sysconfig/network and not in ifcfg-eth0.200

The following errors occured:
014-02-25 15:42:31 INFO 
otopi.plugins.ovirt_hosted_engine_setup.network.bridge bridge._misc:189 
Configuring the management bridge
2014-02-25 15:42:31 DEBUG

2014-02-25 15:42:31 DEBUG otopi.context context._executeMethod:152

Traceback (most recent call last):
   File "/usr/lib/python2.6/site-packages/otopi/context.py", line 142,

     method['method']()
   File 
"/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/ovirt-hosted-engine-setup/network/bridge.py", 
line 231, in _misc
     'gateway=%s' % caps['cfg']['GATEWAY'],
KeyError: 'GATEWAY'

This can be solved by setting GATEWAY in ifcfg-eth* file instead of 
/etc/sysconfig/network


Next, VLAN tagged interfaces don't work:
2014-02-25 15:35:20 INFO 
otopi.plugins.ovirt_hosted_engine_setup.network.bridge bridge._misc:189 
Configuring the management bridge
2014-02-25 15:35:20 DEBUG otopi.context context._executeMethod:152 
method exception
Traceback (most recent call last):
   File "/usr/lib/python2.6/site-packages/otopi/context.py", line 142,

   File 
"/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/ovirt-hosted-engine-setup/network/bridge.py", 
line 194, in _misc
     ].s.getVdsCapabilities()['info']['nics'][nics]
KeyError: 'eth0.200'

So I had to do the following:
- Set switch port to untagged for this VLAN
- Configure eth0 instead of eth0.200
- Run hosted engine setup
- Configure VLAN for ovirtmgmt in oVirt (which surprisingly worked for 
an active interface)
- Configure VLAN tagging on hosts
- Reconfigure switch ports
- Sync networks in oVirt network setup tab

As this was a real pain to do I would love to see support for VLAN 
tagging in hosted engine setup :)


Shall I open bug reports for these 2 issues or are they already known?
