<html><bodyHi,
yes that's exactly what I tried to describe. Thanks Ekin.
There is no switch between 2 hosts/nodes (for ovirtmgmt network). It's
similar to situation when I tried just one host/node and put the
ovirtmgmt network to not connected network interface (will connect it
once we buy second host).
Cheers,
Luf

Hi Lior,
If I'm not mistaken, on Luf's topology, there is no switch on the
management bond (bond0) - just a cross or regular eth cable connecting
physical interfaces on both nodes. So when one node is powered down,
there is no link detected on the other node.
Regards,

Hi Luf,
Apologies, I probably don't understand the details of your L2
toplogy;
how come when you turn off one host it affects the link state
of of the
other one's interfaces?...
Yours, Lior.
