Hi,
I'm using libvirt 0.6.2 to create a Xen guest with a network type
interface (see XML below). When the guest is defined, the interface is
converted to an ethernet type interface. If the guest is started, the
interface is then converted to a bridge type interface.
The progression from network type to ethernet type to bridge type seems
odd to me. With older versions of libvirt, the network type interface
was converted to bridge type during the define, so I'm curious what the
reasoning is here.. Is this the expected behavior?
Also, the XML for the bridge interface in 0.6.2 doesn't include the
source network. This information should be available, so I'm not sure
why its not being set in the XML..
Thanks!
