[Xen-users] XCP: Networking, bridges and bondings

["Angel L. Mateo" <amateo@xxxxx>]

Hello,

	I'm still migrating my Xen (standalone) configuration to XCP and I have 
a doubt: I use network bonding for my interfaces, so with standalong Xen 
I have a bond0 grouping eth0 and eth3 (I have more interfaces, not 
related with Xen configuration by now), then I have a bridge per VLAN 
and I include bond0.<vlanid> to the corresponding bridge.
	I have configure it now XCP with bonding (as described in the 
documentation), but it has a strange behaviour:
* bond0 doesn't appear in /proc/net/bonding
* With brctl show I get:

# brctl show
bridge name     bridge id               STP enabled     interfaces
xapi1           0000.002481a6a178       no              bond0
                                                        eth0
                                                        eth3
xenbr1          0000.002481a6b1c6       no              eth1
xenbr2          0000.00237da6e658       no              eth2

	that is, eth0, eth3 and bond0 are included in the bridge. I have tried 
to manually remove eth0 (or eth3), but I can't:
# brctl delif xapi1 eth0
can't delete eth0 from xapi1: Operation not supported

* Another problem is the MAC associated with xapi1 (my management 
interface) is discover from the other switches of my network in two 
interfaces, that is, the one that connect them to the switch where I 
have eth0 connected to, and the the switch where I have eth1 connected 
to. Is this correct?
* When I boot the machine (or when it has a lot of time of inactivity, 
it's a test environment), I have the 3 o 4 first packages duplicated. Is 
this correct?
	When the same configuration, but with XenServer 5.0 (citrix), the bond0 
appears at /proc/net/bonding, ethX interfaces are not included in 
bridges and I don't have duplicate packages.
