RE: [Xen-devel] Re: [Xen-users] Re: Xen 4.0 - Support for Citrix WHQL-certified Windows PV drivers

[Paul Durrant <Paul.Durrant@xxxxxxxxxx>]

The problem is that your tools are creating a /local/domain/vfb/0 node in 
xenstore. The PV drivers try to gracefully close down the backend for this 
using the same fe closing -> be closing -> fe closed -> be closed state dance 
that it uses for vifs and this is not working.
Since these is actually no fe driver for vfb, I suggest you just make sure this 
node does not exist.
