I'm trying to get a 3.6.1 HE setup going where I have 4 VLANs
(VIDs
101-104) for storage networks, 1 VLAN (VID 100) for ovirtmgmt and 1 more
(VID 1) for everything else. Because I know of no way to manipulate the
network configuration from the management GUI once the HE is running and
with only a single Host, I made the OS configuration as close as possible
to what I'd want when done. This looks like:
Why do you think of this necessary pre-work? I configured (in 3.6.0) an
environment with HE too on a single host and I only preconfigured my bond1
in 802.3ad mode with the interfaces I planned to use for ovirtmgmt and I
left the other interfaces unconfigured, so that all is not used by Network
Manager.
During the "hosted-engine --deploy" setup I got this input:
--== NETWORK CONFIGURATION ==--
Please indicate a nic to set ovirtmgmt bridge on: (em1, bond1,
em2) [em1]: bond1
iptables was detected on your computer, do you wish setup to
configure it? (Yes, No)[Yes]:
Please indicate a pingable gateway IP address [10.4.168.254]:
and then on preview of configuration to apply:
--== CONFIGURATION PREVIEW ==--
Bridge interface : bond1
Engine FQDN : ractorshe.mydomain.local
Bridge name : ovirtmgmt
After setup I configured my vlan based networks for my VMS from the GUI
itself as in the usual way, so that now I have this bond0 created by oVirt
GUI on the other two interfaces (em1 and em2):
[root@ractor ~]# cat /proc/net/bonding/bond0

And then "ip a" command returns:

vnet1 and vnet2 being the virtual network interfaces of my two running VMs.
The only note I can submit is that by default when you set a network in
oVirt GUI with mode=4 (802.3ad), it defaults to configuring it with
"lacp_rate=0" so slow, that I think it is bad, as I read in many articles
(but I'm not a network guru at all)
So that I chose custom mode in the GUI and specified "mode=4 lacp_rate=1"
in options and this was reflected in my configuration as you see above in
bond0 output.
Can we set lacp_rate=1 as a default option for mode=4 in oVirt?
