[Xen-users] Bridge with Xen-interfaces only doesn't work

[Sven Köhler <skoehler@xxxxxx>]

Hi,

maybe it's a well-known problem already. So the problem is:

I have 2 bridges: xenbr0 and xenbr1

The bridges are prepared on startup. xenbr1 contains eth0, xenbr1
contains _no_ interface. "brctl show" looks like this:

# brctl show
bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.001617b458ff       no              eth0
xenbr1          8000.000000000000       no


As you can see, xenbr1 has no mac-address. xenbr0 has "inherited" the
mac-address of eth0 (namely 00:16:17:B4:58:FF).

xenbr1 will have a mac-address, when xend adds the first interface to
the interface. The mac-address of the xen-interfaces (on dom0-side) is
usually something like FE:FF:FF:FF:FF:FF.

xenbr0 as well as xenbr1 have an IP.

The problem:

Somehow the Network between domUs and dom0 doesn't work. ping works, but
TCP/IP doesn't.

Workaround:

I create a tun-interface and add it to xenbr1. Then everything works!


Is this a known problem? Any clue, how i could workaround the problem
more easily than creating a unused tun-interface?


Thanks,
  Sven
