VirtualBox 5.0.10 network problem

[Patrick O'Callaghan]

I have the Oracle version of VBox (VirtualBox-5.0-
5.0.10_104061_fedora22-1.x86_64) and it usually doesn't give any
issues, but now (under F23) my Windows 7 guest has no network access. I
have the appropriate VBox extension installed, and have shutdown and
restarted the guest VM, but to no avail.

My guest network is Bridged on virbr0.

Any hints would be appreciated.
