Re: [Xen-users] xen without xenbr0

[Alexander Hoßdorf <xen-users@xxxxxxxxxxx>]

In my case I only had to start xend.
Then there was no more ethernet connectivity and xen bridges did not 
come up.
And yes, it was a 32 bit system.
I had downloaded the bnx2 drivers from broadcom and compiled them from 
source.
I don't know the version exactly any more, but I can say version 1.6.9 
works well for me.
I think downloading the latest driver and then building it from source 
ois the safest way?!
Cheers,
Alex
