[ovirt-users] Hosted Engine fails if there's a VLAN on the bonded network

[Vinícius Ferrão]

Hello,

I’m deploying oVirt HE on a new DC and the installation failed when configuring the ovirtmgmt interface:

[ INFO  ] Configuring the management bridge
[ ERROR ] Failed to execute stage 'Misc configuration': Failed to setup networks {'ovirtmgmt': {'bonding': 'bond0', 'ipaddr': u'146.164.37.103', 'netmask': u'255.255.255.0', 'defaultRoute': True, 'gateway': u'146.164.37.1'}}. Error: "Command Host.setupNetworks with args {'bondings': {}, 'options': {'connectivityCheck': False}, 'networks': {'ovirtmgmt': {'bonding': 'bond0', 'ipaddr': u'146.164.37.103', 'netmask': u'255.255.255.0', 'defaultRoute': True, 'gateway': u'146.164.37.1'}}} failed:

It appears this happened because on the bond0 interface, the NFS storage network is tagged directly on bond0:

11: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000
    link/ether 40:f2:e9:f3:5c:62 brd ff:ff:ff:ff:ff:ff
    inet 146.164.37.103/24 brd 146.164.37.255 scope global bond0
       valid_lft forever preferred_lft forever
    inet6 fe80::42f2:e9ff:fef3:5c62/64 scope link
       valid_lft forever preferred_lft forever
13: bond0.10 at bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000
    link/ether 40:f2:e9:f3:5c:62 brd ff:ff:ff:ff:ff:ff
    inet 192.168.10.3/28 brd 192.168.10.15 scope global bond0.10
       valid_lft forever preferred_lft forever
    inet6 fe80::42f2:e9ff:fef3:5c62/64 scope link
       valid_lft forever preferred_lft forever

I’ve collected the logs and they are located here for download:

Trying a new install from the ground to see if the issue happens again.

Thanks,
V.
