I've worked around this issue by

Flipping the DEFROUTE parameter on both vlans
AND
Adding "net_persistence =3D ifcfg" to "/etc/vdsm/vdsm.conf"

I'm sure this isn't ideal but it works. If I update configuration using the=
 web UI, it requires me to manually edit and flip the DEFROUTE argument aga=
in.

Is there a way to control how this flag is setup?

Thanks,
Usman

Subject: Hypervisor won't assign default gateway

I have a couple of bonded nics with two bridged vlans. Ovirtmgmt and Primar=
y.
Primary vlan also  has a gateway setup (all using the ovirt UI). The gatewa=
y shows up in the ifcfg file and I've added it to /etc/sysconfig/network as=
 well.

Problem: Upon a reboot the default gateway does not show up (route -n)

One thing did notice is that VDSM is inserting

DEFROUTE=3Dno                  in ifcfg-primary
And
DEFROUTE=3Dyes                 in ifcfg-ovirtmgmt

If is issue the "route add default gateway x.x.x.x" command, it starts work=
ing as expected and the default route also shows up (route -n)

Any ideas?

Thanks,
Usman
