Re: [Xen-users] Multiple bridges in startup

[andrew mathes <amathes@xxxxxxxxxxxx>]

ok, things seem to be ok on my side now, i just put the manual start in my 
auto/ script directory, and seems to start the bridge correctly.  However, 
the secondary vif for every VM seems to be tied to the first bridge, no 
matter how i bring it up (manually:./vif-bridge up domain=VM1 vif=vif1.1 
bridge=xen-br1 mac=AA:00:00:00:00:12)
the hwAddr of the resulting vif is ALWAYS the same as the first bridge 
(xen-br0) and i can't seem to get it to tie to the second bridge ... 
making networking fairly useless on that second nic
thanks for any help-
