[Pkg-xen-devel] Bug#702337: xen-xapi / Open vSwitch not really working

[Daniel Pocock]

Package: xcp-xapi
Version: 1.3.2-14
Severity: important

I chose the Open vSwitch (ovs) networking mode when I installed XCP

# cat /etc/xcp/network.conf
openvswitch

Whenever I boot a VM, I notice that the vif interface is created (e.g.
vif1.0) on dom0, and the vif is added to the ovs bridge (I can see it in
the output of ovs-vsctl show)

However, there is no connectivity, I can't ping the domU

I manually add the vif to a regular Linux bridge:

  brctl addif xenbr0 vif1.0

and then I can ping the domU successfully.

Here is a sample of the ovs-vsctl show output:

# ovs-vsctl show
