Re: [Xen-users] AoE does not discover

Ah...ok, I'll check this out.
are you using AoE in the Dom0, or DomU? if DomU, you can't use routed network,
since AoE isn't IP, even on bridge, i wouldn't be surprised if the bridge
get's in the way of discovery. also, if you use it in DomU, each packet
would pass at least twice thought Dom0 before getting to the DomU.
I am using AoE in the Dom0. This machine is completely diskless. The
machine boots, pxe gets an ip, it tftp's xen, a kernel, and an initrd
and mounts the initrd and runs the init script which loads some modules,
loads the xen module, ip's up an ethernet interface, and then we do
echo 1 > /dev/aoe/discover to find aoe devices. As I understand it the
bridges are ethernet bridges so they should be able to pass raw ethernet
frames. But that does not matter because Dom0 will be getting the AoE
devices and passing them to the DomU's as block devices to be used.
in short, the AoE initiator should be in Dom0
It definitely is.
ethernet. If I run tethereal on the vblade machine looking for some sort
of AoE related traffic I see nothing coming across the wire. I do see
Again, since AoE isn't IP, you should look for ethernet frames type 0x88A2
Hmm...I thought ethereal would show us everything by default, even
non-ip packets.
I am compiling a non-xen kernel now just as a test to see if AoE works
any better without xen.
