[Xen-devel] xen 4.1.1 - Error: Device 0 (vif) could not be connected. Hotplug scripts not working.

[Mark Schneider <ms@xxxxxxxxxxxxxxxxxxxxxx>]

Hello,

I need your kindly help. I am getting an error message when trying 
create an HVM on xen 4.1.1 (debian wheezy with kernel 3.0.0-rc7) (s. 
more details below and attached log files). The same config works as 
expected on xen 4.0 (debian sqeueeze). In both cases dom0 runs in live 
mode from an USB-stick.
