[Xen-users] Networks stops after running xend start

["Mike Lee" <cslinuxboy@xxxxxxxxx>]

Hello Everyone,

     I have successfully installed Xen 3.0.3 (x86_64) tar binaries on my Dell 2900 server.  I also have successfully configured and installed a guest domain.  However,  after the 'xend start' script is ran, I lose all networking.  And if I run 'xend stop' all of the devices associated with a bridged setup are still present (xenbr0, peth0, 
vif0.0, etc.) and my networking is still not working.  The only way to get the network back is to reboot (I don't have xend configured to start on startup).  Below is the output of ifconfig:

     I have searched hi and low for a solution and cannot get a break.  Like I stated above, my configuration is bridged.  I have read the networking doco on the xen wiki and all looks good.  Also, I have looked at the xen logs and everything looks fine with no errors or warnings.  My network card is a Broadcom NetXtreme II BCM5708 Gigabit.  What am I doing wrong?  
     Another question I have is why does peth0 not have the ethernet address of the actual physical card, but eth0 for dom0 does?  Could this be the cause?  Is the xend script broken?  I installed the bridging tools also.  
     Thanks in advance.

Mike
