Re: [Xen-API] guest network not working

[Carlos Reategui <carlos@xxxxxxxxxxxx>]

Here is some additional info.  Hopefully someone has some ideas.  I am thinking of trying the same setup with Debian Wheezy and also with XCP 1.6 to see if they behave the same:

# brctl show

bridge name     bridge id               STP enabled     interfaces

xapi0           8000.feffffffffff       no              vif0.0

                                                        vif7.0

                                                        vif9.0

xapi1           8000.e0db5516cfea       no              bond0

                                                        vif7.1

                                                        vif7.2

                                                        vif9.1

                                                        vif9.2

                                                        vif9.3

xenbr0          8000.e0db5516cfe8       no

xenbr1          8000.e0db5516cfe9       no
