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 otopi.plugins.ovirt_hosted_engine_setup.network.bridge bridge._misc:198 getVdsCaps for eth0: {'addr': '', 'cfg': {'DEVICE': 'eth0', 'PEERDNS': 'no', 'NM_CONTROLLED': 'no', 'BOOTPROTO': 'none', 'HWADDR': '00:25:9 0:75:87:C2', 'ONBOOT': 'yes'}, 'ipv6addrs': ['fe80::225:90ff:fe75:87c2/64'], 'mtu': '1500', 'netmask': '', 'hwaddr': '00:25:90:75:87:c2', 'speed': 1000} 2014-02-25 15:42:31 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, in _executeMethod 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
Currently we look only at ifcfg files for that sort of information. In the future, though, we'll be checking things like dhcp leases for the device to know what is the bootproto.
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, in _executeMethod method['method']() 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?
I'd say for the second one. /etc/sysconfig/network is losing relevance fast and I think the new code that checks live device information is better than parsing that file.
