[one-users] [VMM]Device 2049 (tap) could not be connected. Hotplug scripts not working.

[Łukasz Grabowski]

Hi,

There is a problem with tap: driver in Debian. You can change it to file:
driver.
To do so, you can add driver parameter in sections DISK in VM template:

DISK = [

         ...

         driver = "file:"]


You can also read about the second way of solving the problem here:

Regards,
Łukasz
