Subject: tunctl issues with FC 12 and 2.6.33-rc5

I have built and installed the 2.6.33-rc5 kernel on a machine in which the original distro was Fedora Core 12.  I have a script set up to create a tap device using tunctl but when I boot to the 2.6.33-rc5 kernel I get TUNSETIFF:  Permission Denied.  If I boot to the 2.6.31 based kernel that came with FC 12 the tunctl command works fine and create the tap device.  The problem I need a tap device added to my bridge so I can pass a network interface into one of my KVM virtual machines.

Has anyone seen this problem or might understand why it is occurring?  I checked the netdev archives and found nothing about it there.  Several hours of googling about the internet hasn't provided any insight either.

Thanks,
